Walkthrough

Renames force_load to immediate_hydration, gates immediate hydration behind a Pro license across helpers, controller, configuration, and client-side renderer; logs/shows a Pro-warning and delays hydration until page load when unlicensed; updates docs, tests, and Selenium log ignores.

Changes

Cohort / File(s)	Summary
Ruby helper: Pro gating & immediate_hydration control lib/react_on_rails/helper.rb	Adds IMMEDIATE_HYDRATION_PRO_WARNING and support_pro_features?. internal_react_component records immediate_hydration_requested, forces immediate_hydration = false when Pro unavailable, returns immediate_hydration_requested, replaces data-forced → data-immediate-hydration, and updates pro_warning_badge_if_needed to accept immediate_hydration.
Configuration lib/react_on_rails/configuration.rb, docs/guides/configuration.md	Replaces force_load with immediate_hydration (public attr), default changed from true → false, and documents it as a React on Rails Pro feature.
Controller & Redux store surface lib/react_on_rails/controller.rb, lib/react_on_rails/helper.rb (redux_store)	redux_store signature/payload switched from force_load → immediate_hydration; defaults now pulled from ReactOnRails.configuration.immediate_hydration and forced false when Pro features are unavailable; server payloads use immediate_hydration.
Render options API lib/react_on_rails/react_component/render_options.rb	Replaces public accessor force_load → immediate_hydration, mapping to the new config key.
Client-side renderer: immediate hydration gating node_package/src/ClientSideRenderer.ts	Reads data-immediate-hydration and railsContext.rorPro; if immediate hydration requested but no Pro license, logs IMMEDIATE_HYDRATION_PRO_WARNING and, if document still loading, awaits onPageLoaded() before hydrating; otherwise hydrates immediately.
Streaming & component render paths lib/react_on_rails/helper.rb (stream_react_component, render paths)	Merges immediate_hydration: true defaults where force-load defaults existed; migrates data attributes/payloads to immediate_hydration.
Tests & infra spec/dummy/spec/support/selenium_logger.rb, spec/dummy/spec/system/integration_spec.rb, spec/.../react_on_rails_helper_spec.rb, spec/.../render_options_spec.rb, spec/dummy/app/views/...	Selenium logger ignores the new IMMEDIATE_HYDRATION_PRO_WARNING message; two flaky system tests now skip; specs and fixtures updated to use immediate_hydration and expect data-immediate-hydration attributes; test setup/teardown toggles config.immediate_hydration.
Docs & release notes docs/rails/turbolinks.md, docs/release-notes/15.0.0.md, docs/release-notes/16.0.0.md, CHANGELOG.md	Documentation and release notes updated: rename force_load → immediate_hydration, mark as Pro feature, change defaults and migration guidance, retract v15.0.0 and publish v16.0.0 notes.
Template example change spec/dummy/app/views/pages/turbo_stream_send_hello_world.turbo_stream.erb	Example changed from force_load: true → immediate_hydration: true.

Poem

I nibble code and hop through lines so spry,
If Pro's not here, I'll wait till pages fly.
A tiny badge, a gentle license chime,
We'll hydrate after load — just bide the time. 🐇✨

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Overall Assessment

This PR aims to prevent the force_load feature from being used without a Pro license, which is a good security/licensing enhancement. However, there are several critical issues that need to be addressed.

🔴 Critical Issues

1. Race Condition in Client-Side Validation (node_package/src/ClientSideRenderer.ts)

The current implementation has a problematic race condition:

if (!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading')) {

This condition will trigger the warning and wait even when force_load is false if the page is still loading. This means all non-Pro users will experience delays during page load, regardless of whether they're using the force_load feature.

Recommended fix:

const isComponentForceLoaded = el.getAttribute('data-force-load') === 'true';
if (!railsContext.rorPro && isComponentForceLoaded) {
  console.warn(...);
  // Wait only if we're actually trying to force-load
  if (document.readyState === 'loading') {
    await new Promise<void>((resolve) => {
      onPageLoaded(resolve);
    });
  }
}

2. Incomplete Server-Side Disabling (lib/react_on_rails/helper.rb)

The server-side code disables force_load after already using it:

• Line 61: Badge is generated based on original force_load value
• Line 62: force_load is then disabled

This means the warning badge will still be shown even though the feature is disabled. The logic should be:

render_options.set_option(:force_load, false) unless support_pro_features?
badge = pro_warning_badge_if_needed(render_options.force_load)

3. Inconsistent Implementation Across Methods

• redux_store method directly modifies the local variable instead of using set_option
• This inconsistency could lead to confusion and maintenance issues

🟡 Improvements Needed

1. Missing Test Coverage

The PR lacks tests for the new functionality:

• No tests for the support_pro_features? method
• No tests verifying that force_load is disabled without Pro license
• No client-side tests for the warning and delay behavior

2. Documentation Updates

The CHANGELOG and documentation should be updated to reflect this breaking change for non-Pro users using force_load.

3. Performance Concern

Adding an async wait in the rendering path could impact performance metrics. Consider if this is the best approach or if failing fast would be better.

🟢 Good Practices

1. Clear Error Messages: The warning messages are clear and include a link to get a license
2. Centralized Logic: The support_pro_features? method provides a clean abstraction
3. Backward Compatibility: The changes maintain compatibility for Pro users

Suggested Implementation

Here's a more robust approach:

Ruby side:

def react_component(component_name, options = {})
  # ... existing code ...
  
  # Disable force_load early if no Pro license
  render_options.set_option(:force_load, false) unless support_pro_features?
  
  # Generate badge based on the updated value
  badge = pro_warning_badge_if_needed(render_options.force_load)
  
  # ... rest of the method
end

JavaScript side:

private async render(el: Element, railsContext: RailsContext): Promise<void> {
  const isComponentForceLoaded = el.getAttribute('data-force-load') === 'true';
  
  // Only check and warn if actually trying to use force_load
  if (isComponentForceLoaded && !railsContext.rorPro) {
    console.error(
      "[REACT ON RAILS] The 'force_load' feature requires a React on Rails Pro license. " +
      "This feature has been disabled. " +
      'Please visit https://shakacode.com/react-on-rails-pro to get a license.'
    );
    
    // Remove the force_load attribute to prevent further issues
    el.removeAttribute('data-force-load');
  }
  
  // Continue with normal rendering...
}

Action Items

1. ✅ Fix the race condition in client-side code
2. ✅ Correct the order of operations in server-side code
3. ✅ Add comprehensive tests for the new validation logic
4. ✅ Update CHANGELOG.md
5. ✅ Consider removing the async wait in favor of failing gracefully
6. ✅ Ensure consistent implementation across all helper methods

This is a valuable security/licensing enhancement, but it needs these fixes to avoid impacting all non-Pro users negatively.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Summary

This PR adds proper license validation for the force_load feature, ensuring it's only available with a React on Rails Pro license. The implementation gracefully handles the non-Pro case by disabling the feature and showing warnings.

✅ Strengths

1. Consistent license checking: The new support_pro_features? helper method centralizes the Pro license validation logic, making the code more maintainable.

2. Graceful degradation: When Pro features aren't available, the code properly disables force_load rather than throwing errors.

3. Clear user warnings: The client-side warning message clearly explains the licensing requirement and provides a link to learn more.

4. Defensive programming: The client-side code waits for page load when Pro is not available, preventing potential errors.

🔍 Areas for Improvement

1. Missing Test Coverage (Critical)

The PR checklist indicates tests haven't been added yet. This feature requires comprehensive test coverage:

Ruby side tests needed:

• Test that force_load is disabled when Pro license is invalid in react_component
• Test that force_load is disabled when Pro license is invalid in react_component_hash
• Test that force_load is disabled when Pro license is invalid in redux_store
• Test that warning badge is shown/hidden appropriately

JavaScript side tests needed:

• Test the warning behavior when force_load is used without Pro license
• Test that page load waiting occurs when document is still loading without Pro
• Verify the warning message is logged to console

2. Potential Race Condition (Medium Priority)

In ClientSideRenderer.ts:82-94, the check for document.readyState === 'loading' happens after checking isComponentForceLoaded. This could lead to a race condition where:

// Current logic might miss the warning if page loads between checks
if (!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading'))

Consider checking the document state first or combining the logic more clearly.

3. Documentation Updates Needed (Medium Priority)

The PR checklist indicates documentation hasn't been updated. Consider adding:

• Update to the main README about Pro-only features
• API documentation for the support_pro_features? method
• Migration guide for users who might be using force_load without Pro

4. CHANGELOG Entry Missing (Required)

As per the PR checklist, a CHANGELOG entry should be added at the top of the CHANGELOG.md file describing this change.

5. Code Duplication (Low Priority)

The pattern render_options.set_option(:force_load, false) unless support_pro_features? appears in multiple places (helper.rb:62, helper.rb:219). Consider extracting this into a method like:

def apply_pro_feature_restrictions(render_options)
  render_options.set_option(:force_load, false) unless support_pro_features?
end

6. Type Safety Consideration (Low Priority)

The data-force-load attribute check uses string comparison:

const isComponentForceLoaded = el.getAttribute('data-force-load') === 'true';

Consider using a more robust boolean parsing approach or ensure this attribute is always set consistently.

🔒 Security Considerations

✅ No security issues identified. The implementation properly validates licenses server-side and doesn't expose any sensitive information.

⚡ Performance Considerations

✅ The implementation is efficient. The license check is cached appropriately, and the client-side page load waiting only occurs when necessary.

📝 Recommendations

1. Priority 1: Add comprehensive test coverage before merging
2. Priority 2: Add the missing CHANGELOG entry
3. Priority 3: Update documentation to clarify Pro-only features
4. Priority 4: Consider the race condition fix mentioned above
5. Priority 5: Consider extracting duplicated logic

Overall Assessment

The implementation is solid and follows good practices. The main blocker is the missing test coverage. Once tests are added and the CHANGELOG is updated, this PR will be ready to merge.

Great work on ensuring proper license validation while maintaining backward compatibility! 👍

263-263: Redux store gating applied at the right time

Here you compute the badge using the requested value and then flip force_load before building the store hydration markup. This correctly disables force_load for stores on non‑Pro.

Please add a test asserting that data-force-load is absent from the store hydration script when support_pro_features? is false.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Thank you for this PR that improves the Pro license validation for the force_load feature. I've reviewed the changes and have the following feedback:

✅ Strengths

1. Centralized License Check: The introduction of support_pro_features? helper method is a good refactoring that makes the code more maintainable and DRY.

2. Dual-layer Protection: Implementing both server-side (Ruby) and client-side (TypeScript) protection ensures robust enforcement of the Pro license requirement.

3. Clear Warning Messages: The warning messages on both server and client sides are informative and direct users to the appropriate licensing page.

4. Backward Compatibility: The code gracefully handles non-Pro users by disabling the feature rather than breaking.

⚠️ Areas for Improvement

1. Missing Test Coverage for Client-Side Changes

The PR adds significant logic to ClientSideRenderer.ts but lacks corresponding test coverage. Consider adding tests for:

• The warning message when force_load is used without a Pro license
• The page load waiting behavior
• The interaction between data-force-load attribute and railsContext.rorPro

2. Potential Race Condition

In ClientSideRenderer.ts, the check document.readyState === 'loading' at line 83 could lead to inconsistent behavior:

• If the document transitions from 'loading' to 'interactive' between the check and the Promise creation, the component might wait unnecessarily
• Consider checking the state again inside the Promise or using a more robust approach

3. Documentation Updates Missing

The PR checklist mentions updating documentation, but no documentation files appear to be modified. The following should be updated:

• CHANGELOG.md entry explaining the license validation enhancement
• Any relevant documentation about the force_load feature behavior

4. Incomplete PR Description

The summary section in the PR description still contains the template text and should be updated with a clear description of what was changed and why.

🐛 Potential Issues

1. Client-Side Logic Timing: The condition on line 83 checks both isComponentForceLoaded and document.readyState === 'loading'. This means the warning and wait will trigger even for components without force_load if the document is still loading. Is this intentional?

2. Test Allowlist Update: While adding the warning message to the Selenium logger allowlist (line 30 in selenium_logger.rb) prevents test failures, it also means the warning won't be caught as an error in tests. Consider if this is the desired behavior.

💡 Suggestions

1. Add Integration Tests: Create integration tests that verify the entire flow:

   • Component renders without force_load when Pro is not licensed
   • Warning appears in both console and DOM when appropriate
   • Page load waiting behavior works correctly

2. Refactor Client-Side Check: Consider simplifying the condition:

   const isForceLoadedWithoutPro = !railsContext.rorPro && el.getAttribute('data-force-load') === 'true';
   if (isForceLoadedWithoutPro) {
     // Handle the Pro license requirement
   }

3. Consider Adding Metrics: If you track usage metrics, consider adding telemetry for how often users attempt to use force_load without a Pro license.

🔒 Security Considerations

The implementation looks secure. The license validation happens server-side (where it matters most), and the client-side check serves as a UX enhancement rather than the sole enforcement mechanism.

🎯 Performance Considerations

The page load waiting mechanism is appropriate and shouldn't impact performance for licensed users. The additional checks are minimal and won't affect runtime performance.

---

Overall Assessment: This is a solid implementation that effectively prevents unauthorized use of the Pro feature. The main areas for improvement are adding comprehensive tests for the client-side changes and completing the documentation updates. Once these are addressed, this PR will be ready to merge.

Please let me know if you have any questions about this review or would like clarification on any points!

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Thank you for this contribution! I've reviewed the changes and here's my comprehensive feedback:

🟢 Strengths

• Good initiative to properly enforce Pro license requirements for the force_load feature
• Centralized license checking with the new support_pro_features? method improves maintainability
• Appropriate warning messages on both server and client sides
• Test updates to handle the new warning messages

🔴 Critical Issues

1. Incorrect variable usage in react_component method (lib/react_on_rails/helper.rb:57)

   • Line 57 uses render_options.force_load before render_options is defined
   • This will cause a NameError at runtime
   • Should use options[:force_load] instead

2. Same issue in react_component_hash method (lib/react_on_rails/helper.rb:214)

   • Line 214 has the same problem - using render_options.force_load before it's defined
   • Should use options[:force_load] instead

🟡 Performance Considerations

1. Client-side page load wait
   • The await new Promise pattern forces rendering to wait for full page load when Pro license is missing
   • Consider if this delay is necessary or if a simpler console warning would suffice
   • The delay might negatively impact perceived performance for users

🟠 Code Quality Suggestions

1. Method naming consistency

   • Consider renaming support_pro_features? to pro_features_supported? or has_pro_license? for better readability

2. Badge generation logic

   • The badge generation is called before disabling force_load, but the badge might not be used if force_load is disabled
   • Consider restructuring to avoid unnecessary computation

3. DRY principle

   • The pattern of checking and disabling force_load is repeated in multiple methods
   • Consider extracting this into a helper method:

   def sanitize_force_load_option(options)
     if options[:force_load] && !support_pro_features?
       badge = pro_warning_badge_if_needed(true)
       options[:force_load] = false
       badge
     else
       "".html_safe
     end
   end

🔒 Security Considerations

• No security issues identified
• License validation appears to be properly server-side enforced

🧪 Test Coverage

• ⚠️ Missing unit tests for the new support_pro_features? method
• ⚠️ No integration tests verifying the force_load behavior with/without Pro license
• ✅ Good update to selenium_logger.rb to handle the new warning

📝 Documentation & PR Checklist

• The PR checklist items are unchecked - please complete:
  • Add/update tests to cover these changes
  • Update documentation
  • Update CHANGELOG file
• The PR description template sections need to be filled in properly

🎯 Recommended Actions

1. Fix the critical bugs with undefined render_options variable
2. Add comprehensive tests for the license validation logic
3. Update the CHANGELOG with this breaking change
4. Consider documenting the force_load Pro requirement in the main documentation
5. Complete the PR description with proper summary and remove template text

This is an important change for properly enforcing Pro features, but it needs the critical bugs fixed before it can be merged. Once those are addressed and tests are added, this will be a solid improvement to the codebase.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Overall Assessment

This PR implements important license validation for the force_load feature, ensuring it's only available to Pro users. The implementation is well-structured with both server-side and client-side protections.

✅ Strengths

1. Dual-layer protection: Both Ruby (server) and JavaScript (client) validate the Pro license
2. Graceful degradation: Non-Pro users get warnings but the app continues to work
3. Clean abstraction: New support_pro_features? method improves code readability
4. Proper test exclusion: Updated Selenium logger to ignore Pro license warnings

🔍 Areas for Improvement

1. Missing Test Coverage 🚨

The PR lacks tests for the new functionality:

• No tests for support_pro_features? method
• No tests verifying force_load is disabled without Pro license
• No tests for the client-side warning and page load wait behavior
• No tests for force_load_requested tracking

Recommendation: Add RSpec tests in spec/dummy/spec/helpers/react_on_rails_helper_spec.rb and Jest tests for the client-side validation.

2. Potential Race Condition ⚠️

In ClientSideRenderer.ts line 83:

if (!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading'))

The document.readyState === 'loading' check seems unrelated to force_load validation. This could cause unnecessary delays for non-force_load components when the page is still loading.

Recommendation: Consider separating these concerns or clarifying the logic.

3. Code Duplication 📝

The warning message is duplicated in:

• helper.rb:458-459
• ClientSideRenderer.ts:85-87

Recommendation: Consider centralizing these messages or at least ensuring they stay synchronized.

4. Method Naming Clarity 💭

The support_pro_features? method name is good but could be more descriptive about what it checks.

Recommendation: Consider has_valid_pro_license? or document the method's purpose with a comment.

🐛 Potential Issues

1. Redux Store Force Load

In redux_store method (helper.rb:261), force_load is disabled but the badge is still generated based on the original value. This inconsistency could confuse users.

2. Missing Documentation

The PR checklist indicates documentation needs updating, but no documentation changes are included.

🔒 Security Considerations

The implementation properly validates licenses on both client and server sides, preventing unauthorized use of Pro features. No security vulnerabilities identified.

🚀 Performance Considerations

The async page load wait in the client-side code is appropriate and shouldn't impact performance for licensed users.

📋 PR Checklist Items

Please complete before merging:

• Add comprehensive test coverage
• Update documentation for the new behavior
• Add CHANGELOG entry describing the enhancement
• Clean up the PR description (remove template paragraphs)

💡 Suggestions

1. Consider adding logging/metrics to track how often unlicensed force_load attempts occur
2. Consider a more prominent UI warning for unlicensed usage during development

Verdict

Changes Requested - The core implementation is solid, but the PR needs test coverage and documentation updates before merging. The potential race condition should also be addressed or clarified.

[claude]

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Overall Assessment

This PR improves the handling of the force_load feature when React on Rails Pro is not licensed, which is a good security and licensing enforcement mechanism. The implementation is mostly solid, but there are several areas that need attention.

🟢 Strengths

1. License validation is properly centralized through the new support_pro_features? method
2. Graceful degradation - the feature is disabled rather than breaking when unlicensed
3. User warnings are displayed both server-side (badge) and client-side (console)
4. Test exclusion properly updated to ignore the Pro license warning

🔴 Issues & Concerns

1. Performance Concern - Unnecessary Page Load Wait

In ClientSideRenderer.ts, the code waits for page load even when force_load is false but the document is still loading:

if (!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading'))

This means ANY component rendered during page load without a Pro license will be delayed, not just force-loaded ones. This could significantly impact performance for non-Pro users.

Recommendation: Only wait when isComponentForceLoaded is true:

if (!railsContext.rorPro && isComponentForceLoaded) {

2. Potential Data Integrity Issue

In helper.rb, the force_load_requested value is captured but the actual force_load in render_options is modified. This could lead to inconsistencies if other code relies on render_options.force_load.

Recommendation: Consider using a separate flag or documenting this behavior clearly.

3. Missing Test Coverage

The PR lacks tests for:

• The new support_pro_features? method
• Client-side behavior when force_load is used without Pro license
• The page load waiting mechanism
• The modified behavior in redux_store helper

4. Incomplete Redux Store Handling

In the redux_store method, while the badge is shown, the force_load value is not actually disabled when Pro features aren't supported (unlike in internal_react_component):

def redux_store(store_name, props: {}, defer: false, force_load: nil)
  force_load = ReactOnRails.configuration.force_load if force_load.nil?
  badge = pro_warning_badge_if_needed(force_load)
  force_load = false unless support_pro_features?  # This line is after badge generation
  
  redux_store_data = { store_name: store_name,
                       props: props,
                       force_load: force_load }  # Still uses the potentially true value

The force_load = false unless support_pro_features? line appears to be placed incorrectly and may not affect the actual store data.

5. Documentation Updates Missing

The PR checklist indicates documentation needs updating but none are included. The CHANGELOG also needs an entry.

🟡 Suggestions for Improvement

1. Extract the license checking logic into a before_filter or concern to avoid duplication
2. Add integration tests that verify the full flow with and without Pro license
3. Consider using a feature flag pattern for Pro features to make the code more maintainable
4. Add JSDoc comments to the TypeScript code explaining the Pro license check behavior

🔒 Security Considerations

The implementation properly prevents unauthorized use of Pro features, which is good for license protection. No security vulnerabilities identified.

📊 Performance Considerations

The current implementation may unnecessarily delay component rendering for non-Pro users during page load. This should be addressed before merging.

✅ Action Items Before Merge

1. Fix the performance issue in ClientSideRenderer.ts
2. Correct the redux_store force_load handling
3. Add comprehensive test coverage
4. Update documentation and CHANGELOG
5. Consider the architectural improvements suggested above

Let me know if you need help with any of these improvements!

Code Review: Enhance Pro license validation for force_load feature

Thank you for this PR! I've reviewed the changes to enforce Pro license requirements for the force_load feature. Here's my comprehensive feedback:

🟢 Strengths

1. Clear separation of concerns: The introduction of support_pro_features? method provides a clean, reusable way to check license validity.
2. Proper warning implementation: Warning badge display logic is well-handled while still disabling the unauthorized feature.
3. Client-side protection: Adding JS-side validation in ClientSideRenderer.ts provides defense-in-depth.
4. Test filter updates: Appropriately ignoring the license warning in Selenium tests to prevent false failures.

🔴 Critical Issues

1. Race condition in ClientSideRenderer.ts: The current implementation has a potential race condition:

   if (!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading'))

   When document.readyState === 'loading', components without force_load will also wait for page load, which is unintended behavior. This should be:

   if (!railsContext.rorPro && isComponentForceLoaded)

2. Missing test coverage: The PR lacks tests for the new JavaScript behavior. Consider adding:

   • Unit tests for the ClientSideRenderer changes
   • Integration tests verifying the page load wait behavior
   • Tests confirming non-force_load components aren't affected

🟡 Performance & Security Considerations

1. Performance: The onPageLoaded wait mechanism is appropriate but could benefit from a timeout to prevent indefinite blocking in edge cases.

2. Security: Good defense-in-depth approach with both server and client validation. However, consider that determined users could still bypass client-side checks. The server-side enforcement is the critical security boundary.

📝 Code Quality Suggestions

1. Helper.rb refactoring: The pattern of capturing force_load_requested and then modifying render_options is repeated. Consider extracting this to a method:

   def adjust_force_load_for_license(render_options)
     force_load_requested = render_options.force_load
     render_options.set_option(:force_load, false) unless support_pro_features?
     force_load_requested
   end

2. redux_store method: The redux_store method directly modifies force_load but doesn't track the original request like other methods. Consider consistency:

   def redux_store(store_name, props: {}, defer: false, force_load: nil)
     force_load = ReactOnRails.configuration.force_load if force_load.nil?
     force_load_requested = force_load  # Track original request
     force_load = false unless support_pro_features?
     badge = pro_warning_badge_if_needed(force_load_requested)

3. Test naming: The pending tests in integration_spec.rb are marked as "Flaky test - needs investigation". If these are intentionally disabled due to this PR's changes, update the pending message to be more specific.

📋 Checklist Items

Per your PR checklist:

• ❌ Tests: Need JavaScript test coverage for ClientSideRenderer changes
• ❌ Documentation: Consider updating docs to clarify force_load Pro requirement
• ❌ CHANGELOG: Entry should be added describing this enforcement change

💡 Additional Recommendations

1. Consider adding a configuration option to customize the warning message or disable it entirely for production environments where console warnings might not be appropriate.

2. The warning message appears both server-side (Rails logger) and client-side (console.warn). Ensure this isn't too noisy in development environments.

3. Consider rate-limiting or caching the license check to avoid performance impact on high-traffic pages.

✅ Overall Assessment

This is a well-intentioned PR that properly enforces Pro license requirements. With the critical race condition fix and additional test coverage, this will be a solid improvement to the codebase. The approach of disabling the feature while showing warnings is user-friendly and maintains backward compatibility.

Please address the race condition issue and add test coverage before merging. The other suggestions are improvements that could be addressed in this PR or as follow-ups.

262-262: Defer path drops the Pro badge for force_loaded stores

When defer: true, you compute badge but never render it; users won’t see the Pro notice though the feature is disabled.

Minimal patch:

 def redux_store(store_name, props: {}, defer: false, force_load: nil)
   force_load = ReactOnRails.configuration.force_load if force_load.nil?
   badge = pro_warning_badge_if_needed(force_load)
   force_load = false unless support_pro_features?
 
-  redux_store_data = { store_name: store_name,
-                       props: props,
-                       force_load: force_load }
+  redux_store_data = { store_name: store_name,
+                       props: props,
+                       force_load: force_load,
+                       force_load_requested: !!force_load || !!ReactOnRails.configuration.force_load }
   if defer
     registered_stores_defer_render << redux_store_data
     "YOU SHOULD NOT SEE THIS ON YOUR VIEW -- Uses as a code block, like <% redux_store %> " \
       "and not <%= redux store %>"
   else
     registered_stores << redux_store_data
     result = render_redux_store_data(redux_store_data)
     (badge + prepend_render_rails_context(result)).html_safe
   end
 end

And render the badge for deferred stores:

 def redux_store_hydration_data
   return if registered_stores_defer_render.blank?
 
   registered_stores_defer_render.reduce(+"") do |accum, redux_store_data|
-    accum << render_redux_store_data(redux_store_data)
+    accum << pro_warning_badge_if_needed(redux_store_data[:force_load_requested])
+    accum << render_redux_store_data(redux_store_data)
   end.html_safe
 end

452-455: Centralized helper for license validation — good; expose validity to rails_context for client gating

Method looks fine. To align client warnings with license validity (not just gem presence), add a rorProValid flag to rails_context using this method so ClientSideRenderer can gate on validity.

Proposed addition in rails_context:

-          rorPro: ReactOnRails::VERSION,
+          rorPro: ReactOnRails::VERSION,
+          rorProValid: ReactOnRails::Utils.react_on_rails_pro_licence_valid?,

Confirm the TS code reads railsContext.rorProValid when available and falls back to rorPro for older servers.

Learning: In React on Rails, the force_load feature includes both explicit `data-force-load="true"` usage and the ability to hydrate components during the page loading state (`document.readyState === 'loading'`). Both capabilities require a Pro license, so the condition `!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading')` correctly gates both scenarios.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Thank you for this contribution! I've reviewed the changes and have the following feedback:

✅ Strengths

1. Good separation of concerns: The new support_pro_features? method nicely encapsulates the license check logic
2. Consistent validation: Both server-side (Ruby) and client-side (JavaScript) now properly validate the Pro license
3. User-friendly warnings: Clear warning messages help users understand the license requirement
4. Backward compatibility: The changes don't break existing functionality for users with valid Pro licenses

🔍 Areas for Improvement

1. Missing Test Coverage ⚠️

The PR lacks tests for the new functionality:

• No tests for the support_pro_features? method
• No tests verifying that force_load is disabled when Pro features aren't supported in internal_react_component
• No tests for the client-side warning and page load waiting behavior
• Consider adding tests in spec/dummy/spec/helpers/react_on_rails_helper_spec.rb

2. Potential Race Condition 🐛

In node_package/src/ClientSideRenderer.ts:82-93, the client-side check happens after the component might have already started rendering. The warning appears but the force_load functionality might still partially execute before being disabled. Consider checking earlier in the rendering pipeline.

3. Inconsistent Force Load Handling 🤔

• In redux_store method (helper.rb:261), force_load is set to false directly
• In internal_react_component (helper.rb:677), it uses set_option method
• Consider using a consistent approach for clarity

4. Documentation Missing 📝

The PR checklist indicates documentation needs updating but none is included. Consider:

• Updating the main documentation about Pro license requirements
• Adding JSDoc comments for the new client-side logic
• Documenting the support_pro_features? method

5. Incomplete PR Description ✏️

The summary section still contains placeholder text. Please update it with a clear description of what this PR fixes or improves.

🐞 Potential Issues

1. Flaky Tests: Two tests are marked as pending with "Flaky test - needs investigation". These should be fixed rather than skipped:

   • spec/dummy/spec/system/integration_spec.rb:92
   • spec/dummy/spec/system/integration_spec.rb:103

2. Performance Consideration: The client-side waiting for page load (onPageLoaded) could delay component rendering for all users without Pro licenses. Consider if this is the intended behavior or if a more graceful degradation would be better.

📋 Checklist Items

Please complete these before merging:

• Add comprehensive test coverage for new functionality
• Update documentation about Pro license requirements
• Fix or properly investigate the flaky tests
• Update CHANGELOG.md with this change
• Complete the PR description summary

💡 Suggestions

1. Consider extracting the warning message to a constant since it's duplicated in Ruby and JavaScript
2. Add integration tests that verify the end-to-end behavior when force_load is used without a Pro license
3. Consider adding metrics/telemetry to track how often users hit this limitation

Overall, this is a good improvement to the Pro license validation, but it needs test coverage and documentation updates before it's ready to merge. The code quality is good, and the approach is sound. Once the above items are addressed, this will be a solid enhancement to the library.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

🎯 Summary

This PR enhances the Pro license validation for the force_load feature by centralizing license checks and preventing its use without a valid Pro license. The changes are well-structured and follow defensive programming practices.

✅ Strengths

1. Good architectural decision: Introducing support_pro_features? method centralizes license validation logic, making the code more maintainable.

2. Defensive implementation: The dual approach of both disabling the feature server-side and adding client-side warnings provides robust protection.

3. User-friendly warnings: Clear warning messages with links to the Pro license page help users understand the limitation.

🔍 Issues & Suggestions

1. Missing Test Coverage 🚨

The new support_pro_features? method lacks test coverage. Consider adding specs to verify:

• The method correctly delegates to ReactOnRails::Utils.react_on_rails_pro_licence_valid?
• The force_load behavior when Pro features are/aren't supported
• The client-side warning logic in ClientSideRenderer.ts

2. Potential Race Condition ⚠️

In ClientSideRenderer.ts line 82-93, the check for document.readyState === 'loading' might miss the warning if the component renders after page load but still uses force_load. Consider:

const isComponentForceLoaded = el.getAttribute('data-force-load') === 'true';
if (!railsContext.rorPro && isComponentForceLoaded) {
  console.warn(...);
  // Only wait if page is still loading
  if (document.readyState === 'loading') {
    await new Promise<void>((resolve) => {
      onPageLoaded(resolve);
    });
  }
}

3. Inconsistent Badge Display Logic 🤔

In helper.rb, the badge is shown based on force_load_requested but the actual feature is disabled. This could confuse users who see the badge but don't understand why the feature isn't working. Consider adding more context to the badge message or logging.

4. Documentation Updates Missing 📝

The PR checklist indicates documentation updates are pending. Please ensure:

• Update README or relevant docs about Pro license requirements for force_load
• Add CHANGELOG entry describing this breaking change for non-Pro users

5. Flaky Tests Marked as Pending ⚠️

Two tests have been marked as pending with "Flaky test - needs investigation". These should be investigated and fixed rather than disabled, especially since they test the force_load functionality directly.

🔐 Security Considerations

No security vulnerabilities identified. The license check is performed server-side, which is the correct approach.

⚡ Performance Considerations

The additional onPageLoaded wait in the client-side code only triggers for non-Pro users attempting to use Pro features, so performance impact is minimal for legitimate users.

💡 Additional Recommendations

1. Consider adding a feature flag or configuration option to completely disable Pro feature checks in development/test environments.

2. The warning message appears both server-side (badge) and client-side (console). Consider consolidating to avoid duplicate warnings.

3. Add integration tests that specifically verify the behavior when force_load is attempted without a Pro license.

✔️ Approval Status

The code changes are generally good, but I recommend addressing the test coverage gap and investigating the flaky tests before merging. The missing documentation should also be completed as indicated in the PR checklist.

[claude]

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Overall Assessment

This PR successfully implements Pro license validation for the force_load feature with graceful degradation for non-Pro users. The implementation is generally solid but requires attention to several important issues before merging.

✅ Strengths

1. Centralized license checking: The new support_pro_features? method provides a clean abstraction for Pro license validation
2. Graceful degradation: Properly disables force_load when Pro license is unavailable rather than throwing errors
3. Clear user communication: Warning messages clearly explain the licensing requirement with actionable links
4. Defensive programming: Client-side code prevents potential errors by waiting for page load when necessary

🔴 Critical Issues

1. Race Condition in Client-Side Logic (node_package/src/ClientSideRenderer.ts:82-83)

The current condition has a logic issue:

if (!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading'))

This will trigger the warning and delay for ALL non-Pro users during page load, even when they're not using force_load.

Recommended fix:

const isComponentForceLoaded = el.getAttribute('data-force-load') === 'true';
if (isComponentForceLoaded && !railsContext.rorPro) {
  console.warn('[REACT ON RAILS] The force_load feature requires...');
  // Only wait if page is still loading AND we're actually using force_load
  if (document.readyState === 'loading') {
    await new Promise<void>((resolve) => {

}

2. Inconsistent Implementation (lib/react_on_rails/helper.rb:261)

The redux_store method directly modifies the local variable instead of using set_option like other methods. For consistency:

# Instead of:
force_load = false unless support_pro_features?
# Consider using a consistent approach across all methods

🟡 Required Before Merge

1. Missing Test Coverage

The PR checklist indicates tests haven't been added. Critical test cases needed:

Ruby tests:

• Verify force_load is disabled when Pro license is invalid in react_component
• Verify force_load is disabled when Pro license is invalid in react_component_hash
• Verify force_load is disabled when Pro license is invalid in redux_store
• Test the new support_pro_features? method
• Verify warning badge behavior

JavaScript tests:

• Test warning is logged when force_load is used without Pro license
• Test page load waiting behavior
• Verify component still renders after the wait

2. CHANGELOG Entry Missing

Per the PR checklist, please add a CHANGELOG entry at the top of CHANGELOG.md describing this breaking change for non-Pro users.

3. Documentation Updates

The PR checklist indicates documentation needs updating. Consider:

• Update README about Pro-only features
• Document the support_pro_features? method
• Add migration guide for users currently using force_load without Pro

🔍 Minor Improvements

1. Consider extracting repeated logic: The pattern of disabling force_load appears in multiple places and could be extracted into a helper method

2. Type safety: The data-force-load attribute comparison could use more robust boolean parsing

3. Memory consideration: The onPageLoaded callback might retain references. Consider if cleanup is needed.

⚡ Performance

✅ No significant performance concerns. License checks are cached appropriately.

🔒 Security

✅ Implementation properly validates licenses server-side and doesn't expose sensitive information.

📋 Action Items

1. ⬜ Fix the race condition in client-side code (Critical)
2. ⬜ Add comprehensive test coverage
3. ⬜ Update CHANGELOG.md
4. ⬜ Update documentation
5. ⬜ Consider making the implementation consistent across all helper methods

Conclusion

This is a valuable licensing enhancement that properly gates Pro features. Once the race condition is fixed and tests are added, this will be ready to merge. The implementation demonstrates good engineering practices with proper server-side validation and graceful client-side handling.

Great work on ensuring backward compatibility for Pro users while properly enforcing licensing! 👍

Pull Request Review

Thank you for this enhancement to Pro license validation for the force_load feature. The implementation is well-structured and addresses an important security concern. Here's my detailed review:

✅ Strengths

1. Good separation of concerns: Introducing support_pro_features? method improves code readability and makes license validation logic reusable.

2. Defensive programming: The implementation properly disables the force_load feature when Pro license is not valid, preventing unauthorized usage.

3. Clear warning messages: Both server and client-side warnings provide clear guidance to users about license requirements.

4. Proper badge handling: The code correctly tracks the originally requested force_load value to display warnings while still disabling the feature.

🐛 Issues & Concerns

1. Missing test coverage: The PR lacks tests for the new functionality, particularly:

   • Tests for the new support_pro_features? method
   • Tests verifying that force_load is disabled when Pro license is invalid
   • Client-side tests for the new ClientSideRenderer behavior
   • Tests for the redux_store method changes

2. Pending test cases: Two test cases have been marked as pending with "Flaky test - needs investigation". These should be fixed rather than skipped, as they appear related to the force_load feature.

3. Incomplete PR description: The summary section still contains template text and should be updated with actual context about the changes.

🔧 Suggestions for Improvement

1. Add comprehensive test coverage:

   # spec/dummy/spec/helpers/react_on_rails_helper_spec.rb
   describe '#support_pro_features?' do
     context 'when Pro license is valid' do
       before { allow(ReactOnRails::Utils).to receive(:react_on_rails_pro_licence_valid?).and_return(true) }
       it { expect(helper.send(:support_pro_features?)).to be true }
     end
     
     context 'when Pro license is invalid' do
       before { allow(ReactOnRails::Utils).to receive(:react_on_rails_pro_licence_valid?).and_return(false) }
       it { expect(helper.send(:support_pro_features?)).to be false }
     end
   end
   
   describe '#internal_react_component with force_load' do
     context 'when Pro license is invalid and force_load is true' do
       it 'disables force_load in render_options' do
         # Test that render_options.force_load is set to false
       end
     end
   end

2. Add client-side tests: Create tests for ClientSideRenderer to verify the warning behavior and page load waiting logic.

3. Consider race conditions: The client-side implementation waits for page load when force_load is used without Pro license. Consider edge cases where this might cause issues with rapid navigation or Turbo frames.

4. Documentation: Update the CHANGELOG.md as indicated in the PR checklist.

🔒 Security Considerations

• ✅ The implementation properly prevents unauthorized use of Pro features
• ✅ No secrets or sensitive data are exposed
• ✅ Warning messages don't reveal implementation details

💡 Performance Considerations

• The onPageLoaded promise in ClientSideRenderer could potentially delay rendering for non-Pro users. Consider if there's a more graceful degradation strategy.

📝 Required Actions

1. Add comprehensive test coverage for all modified methods
2. Fix the flaky tests instead of marking them as pending
3. Update the PR description with actual context
4. Update CHANGELOG.md with the changes

Overall, this is a valuable enhancement that improves license validation. With the addition of proper test coverage and fixing the flaky tests, this will be ready to merge.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Overall Assessment

This PR effectively addresses the Pro license validation for the force_load feature, providing both server-side and client-side protection. The implementation is sound, but there are several areas that could be improved.

Strengths ✅

1. Dual-layer protection: Both Ruby (server-side) and TypeScript (client-side) validation ensures the feature cannot be used without a Pro license
2. User-friendly approach: Shows warning badges while gracefully degrading functionality
3. Clean abstraction: The new support_pro_features? method improves code readability

Issues & Recommendations 🔍

1. Missing Test Coverage ⚠️

The new support_pro_features? method lacks dedicated unit tests. While existing tests cover the behavior indirectly, explicit tests would be valuable:

• Add tests for support_pro_features? method
• Add tests for the internal_react_component force_load override behavior
• Add client-side tests for the new warning and page load wait logic

2. Performance Consideration 🚀

In ClientSideRenderer.ts, the page load wait could cause unnecessary delays:

await new Promise<void>((resolve) => {
  onPageLoaded(resolve);
});

Consider adding a timeout or making this behavior configurable for better UX.

3. Redux Store Inconsistency 🔧

In the redux_store method (lib/react_on_rails/helper.rb:260), force_load is disabled after creating the badge:

badge = pro_warning_badge_if_needed(force_load)
force_load = false unless support_pro_features?

This could be refactored to match the pattern used in internal_react_component for consistency.

4. Documentation Updates Missing 📝

The PR checklist mentions updating documentation, but no documentation changes are included. Consider adding:

• CHANGELOG.md entry
• Documentation about Pro license requirements for force_load
• Migration guide for users currently using force_load without a license

5. Flaky Tests 🧪

Two tests are marked as pending with "Flaky test - needs investigation" (spec/dummy/spec/system/integration_spec.rb:93,105):

• Integration spec for "changes name in message according to input"
• Integration spec for "force load hello-world component immediately"

These should be investigated and fixed rather than skipped, as they might be related to the force_load changes.

6. Security Consideration 🔒

The client-side check can be bypassed by modifying JavaScript. While the server-side protection prevents actual usage, consider logging attempts to use force_load without a license for monitoring purposes.

Code Quality Suggestions 💡

1. Extract license checking logic: Consider creating a dedicated service class for Pro license validation to centralize this logic
2. Add type safety: The data-force-load attribute checking could benefit from TypeScript enums or constants
3. Improve error messaging: The console warning could include more specific guidance on how to obtain a Pro license

Security Review ✅

No security vulnerabilities identified. The implementation properly validates licenses on both client and server sides.

Performance Impact ✅

Minimal performance impact, though the client-side page load wait could affect perceived performance for non-Pro users.

Conclusion

The PR successfully implements the Pro license validation with a good approach. However, it needs:

1. Comprehensive test coverage for new functionality
2. Documentation updates
3. Investigation of flaky tests
4. Minor refactoring for consistency

Once these items are addressed, this PR will be ready for merge. Great work on the dual-layer protection approach! 👍

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Thank you for this PR! I've reviewed the changes and have the following feedback:

✅ Strengths

1. Clear Naming Convention: The rename from force_load to immediate_hydration better describes the feature's purpose and aligns with React terminology.

2. Robust License Validation: The addition of the support_pro_features? helper method provides a cleaner abstraction for license checks.

3. Graceful Fallback: The client-side fallback (waiting for page load when Pro license is missing) ensures the application still works without the Pro feature.

4. Proper Warning System: Both server-side and client-side warnings are clear and helpful, directing users to the Pro license page.

🔍 Areas for Improvement

1. Breaking Change Documentation

This is a breaking change that needs more prominent documentation:

• The configuration option changes from force_load to immediate_hydration
• The default value changes from true to false
• All existing uses of force_load in user code will need updating

Recommendation: Add a migration guide in the CHANGELOG and consider a deprecation warning for force_load usage.

2. Test Coverage Gaps

While tests exist for the badge warning, there's missing coverage for:

• The new support_pro_features? method
• Client-side fallback behavior when Pro license is missing
• The interaction between immediate_hydration and Redux stores

The two skipped tests ("Flaky test - needs investigation") should be fixed rather than skipped.

3. Performance Consideration

// In ClientSideRenderer.ts
if (isImmediateHydrationRequested && !hasProLicense) {
  console.warn(IMMEDIATE_HYDRATION_PRO_WARNING);
  if (document.readyState === 'loading') {
    await new Promise<void>((resolve) => {
      onPageLoaded(resolve);
    });
  }
}

This adds an extra async wait in the render path. Consider moving the license check earlier in the pipeline to avoid runtime overhead.

4. Configuration Inconsistency

In stream_react_component, the default is set to true:

options = options.merge(immediate_hydration: true) unless options.key?(:immediate_hydration)

But the global default is false. This inconsistency could confuse users.

5. Security: License Check Bypass

The client-side can still attempt immediate hydration if someone modifies the DOM attribute. While this isn't a critical security issue, consider:

• Server-side should not render the data-immediate-hydration attribute when Pro license is missing
• This is partially implemented but could be more consistent

📝 Specific Suggestions

1. Update PR Description: The checklist items (tests, documentation, CHANGELOG) are unchecked. Please complete these or explain why they're not applicable.

2. Fix Test References: Update test descriptions and variable names that still reference force_load:

   # Line 385-386 in react_on_rails_helper_spec.rb
   context "when Pro license is NOT installed and force_load is true" do
     subject(:react_app) { react_component("App", props: props, force_load: true) }

3. Consider Backwards Compatibility: Add a deprecation path:

   if options.key?(:force_load)
     ActiveSupport::Deprecation.warn("force_load is deprecated, use immediate_hydration instead")
     options[:immediate_hydration] = options.delete(:force_load)
   end

4. Documentation Clarity: The configuration comment could be clearer about the Pro requirement:

   # React on Rails Pro (licensed) feature - enables immediate hydration
   # Note: This feature requires a valid Pro license to function
   # Without a license, components will fall back to standard page-load hydration

🐛 Potential Bugs

1. The helper method silently disables the feature without informing the caller:

   render_options.set_option(:immediate_hydration, false) unless support_pro_features?

   This happens after storing immediate_hydration_requested, but the actual render_options object is modified. Consider if this could cause confusion in debugging.

2. The Redux store hydration might not handle the license check consistently with components.

✨ Overall Assessment

This PR successfully implements the Pro license validation for the immediate hydration feature. The code quality is good, and the approach is sound. However, it needs:

1. Better handling of the breaking change
2. Complete test coverage
3. Documentation updates
4. Minor refinements for consistency

Once these items are addressed, this will be a solid enhancement to the React on Rails Pro feature set.

369-392: Expose server-side Pro license validity to the client and use it for client gating

rails_context currently exposes only rorPro (gem presence) while server-side gating uses ReactOnRails::Utils.react_on_rails_pro_licence_valid? — the client still checks railsContext.rorPro, causing a mismatch. Add an explicit licensed flag and switch client checks to it.

• lib/react_on_rails/helper.rb — in rails_context add:
  rorProLicensed: ReactOnRails::Utils.react_on_rails_pro_licence_valid?
• node_package/src/types/index.ts — add rorProLicensed: boolean to the RailsContext type (next to rorPro).
• node_package/src/ClientSideRenderer.ts — replace all uses of railsContext.rorPro with railsContext.rorProLicensed (e.g. const hasProLicense = railsContext.rorPro -> railsContext.rorProLicensed) and any other client-side license checks.
• Update tests/docs that assert railsContext shape (spec/dummy/system/rails_context_spec.rb, related specs/docs) to expect the new property.

259-265: Redux store gating: order is right; consider badge/log duplication and deferred stores

• Correct: compute badge before gating and then force immediate_hydration = false for non‑Pro so markup is clean.
• Two follow-ups:
  • The badge can render multiple times if several stores/components request immediate hydration. Suggest “once per request” dedupe (see diff on pro_warning_badge_if_needed below).
  • If a store is registered with defer: true, the badge won’t render server‑side at all. If you want parity, consider emitting the badge from redux_store_hydration_data when any deferred store requested immediate hydration without a license. Optional.

Learning: In React on Rails, the force_load feature includes both explicit `data-force-load="true"` usage and the ability to hydrate components during the page loading state (`document.readyState === 'loading'`). Both capabilities require a Pro license, so the condition `!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading')` correctly gates both scenarios.

Gate immediate_hydration in the controller or centralize its handling

Controller path (lib/react_on_rails/controller.rb — def redux_store, ~lines 17–23) uses ReactOnRails.configuration.immediate_hydration and appends redux_store_data to @registered_stores_defer_render without calling support_pro_features? or emitting the Pro badge; helper path (lib/react_on_rails/helper.rb — redux_store and pro_warning_badge_if_needed) does enforce gating. Either add the same gating in the controller (call pro_warning_badge_if_needed and set immediate_hydration = false unless support_pro_features?) or consolidate immediate_hydration normalization into a single shared method used by both paths.

🤖 Prompt for AI Agents

In lib/react_on_rails/controller.rb around lines 17 to 22, the controller path
uses ReactOnRails.configuration.immediate_hydration and registers
redux_store_data without applying the Pro-feature gating that the helper path
enforces; update the controller to either (a) call the same
pro_warning_badge_if_needed helper and set immediate_hydration = false unless
support_pro_features? before building redux_store_data, or (b) move the
immediate_hydration normalization/gating into a shared private method used by
both controller and helper and call that here so immediate_hydration is always
falsified when Pro features are unavailable and the Pro badge/warning is emitted
consistently.

29-39: Test isolation for immediate_hydration default is fine; tiny lifecycle nit.

Before/after is OK. You could use around(:each) to co-locate setup/teardown, but not required.

---

370-388: Consider also asserting the data attribute when toggling immediate_hydration.

You’re checking the presence/absence of the “loaded” script. Add a quick assertion that the component spec tag omits (or sets) data-immediate-hydration when immediate_hydration: false vs default to catch any future regressions in markup.

2-2: Switch to immediate_hydration looks correct; verify behavior without Pro in demo envs.

This aligns with the rename and Pro gating. If this dummy view is exercised outside specs (where Pro is stubbed true), expect the client to delay hydration until window load and emit a warning. If that’s undesirable in demo, consider immediate_hydration: false.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Thank you for this PR! I have reviewed the changes and have the following feedback:

✅ Strengths

1. Clear naming improvement: Renaming force_load to immediate_hydration better describes what the feature actually does
2. Proper license gating: Good implementation of Pro feature validation both server-side and client-side
3. Graceful fallback: Excellent handling when Pro license is not available - falls back to standard behavior instead of breaking
4. Consistent implementation: The change is applied consistently across Ruby and TypeScript/JavaScript code
5. Good documentation updates: Release notes and configuration docs clearly explain the feature and its Pro-only nature

🔍 Areas for Improvement

1. Test Coverage Gaps

• Missing tests for the new support_pro_features? helper method
• No integration tests verifying the client-side fallback behavior when Pro license is missing
• Consider adding tests for the warning badge display logic

2. Potential Performance Impact

• In ClientSideRenderer.ts, when immediate hydration is requested without a Pro license, the code waits for page load. Consider if this delay should be logged for debugging purposes

3. Code Organization

• The IMMEDIATE_HYDRATION_PRO_WARNING constant is duplicated in both Ruby and TypeScript. Consider centralizing this messaging strategy

4. Documentation Completeness

• The PR description template sections (Summary, Other Information) were not filled out
• Consider adding migration examples for users upgrading from force_load to immediate_hydration

🐛 Potential Issues

1. Breaking Change Management

The default value change from force_load: true to immediate_hydration: false is a breaking change. While documented, consider:

• Adding a deprecation warning for force_load usage to ease migration
• Providing a configuration migration helper

2. Store Hydration Logic

In helper.rb:263, the immediate_hydration is set to false for stores when Pro features are not supported, but the badge logic runs before this check. This could show a badge even when the feature is disabled.

3. Test Configuration Side Effects

In react_on_rails_helper_spec.rb, setting immediate_hydration: true in the before block affects all tests in that file. Consider using RSpec around hooks or resetting in an ensure block.

💡 Suggestions

1. Add method documentation: The new support_pro_features? method would benefit from YARD documentation
2. Consider feature detection: Instead of checking license validity multiple times, consider caching the result per request
3. Improve error messages: Add more context about what immediate hydration provides and why it is a Pro feature

🔒 Security Considerations

No security issues identified. The license validation is properly server-side, preventing client-side bypassing.

✅ Overall Assessment

This is a well-implemented feature flag for Pro functionality. The code quality is good, and the approach is sound. With the suggested improvements to test coverage and handling of edge cases, this will be a solid addition to the codebase.

Recommendation: Approve with minor changes - address the test coverage gaps and consider the breaking change migration path improvements.

Code Review for PR #1781: Enhance Pro license validation for immediate_hydration feature

Thank you for this PR that properly gates the immediate_hydration feature behind a Pro license. I've conducted a thorough review and here are my findings:

Strengths

1. Clear API Improvement: The rename from force_load to immediate_hydration better describes the feature's behavior and intent.

2. Proper License Enforcement: The feature is correctly gated behind Pro license checks on both Ruby and JavaScript sides, with appropriate fallback behavior for unlicensed users.

3. Good Documentation: Release notes and migration guide are comprehensive, clearly explaining the breaking changes and migration path.

4. Backward Compatibility Handling: The approach of retracting v15.0.0 and introducing v16.0.0 with the corrected API shows good version management practices.

Issues to Address

1. Version Consistency

The Gemfile.lock shows version 16.0.0 but there's no corresponding version bump in the gemspec file. Please update lib/react_on_rails/version.rb to match.

2. Test Coverage Concerns

• Two integration tests have been skipped with 'Flaky test - needs investigation' comments
• These tests appear to be related to the immediate_hydration feature
• Please investigate and fix these tests rather than skipping them, as they're testing critical functionality

3. Configuration Default Change

The default for immediate_hydration is now false (was true for force_load). While this is the correct approach for a Pro feature, this breaking change should be prominently highlighted in the migration guide as it could affect existing applications expecting the old default behavior.

Suggestions for Improvement

1. Consider a deprecation warning: For users still using force_load in their code, add a deprecation warning to help with migration.

2. Client-side warning timing: The client-side warning with page load wait is good, but consider adding a console.time/timeEnd to show users exactly how much delay the Pro license would save them.

3. Test helper configuration: The test helper sets config.immediate_hydration = true in the before block but resets to false in after. Consider using RSpec's around hooks or shared contexts for cleaner configuration management.

4. PR Description: The PR description still has template text. Please update it with actual implementation details and ensure the checklist items are completed.

Security

No security issues identified. The feature properly validates licenses and doesn't expose any sensitive information.

Performance

The performance implications are positive - unlicensed users get standard behavior while licensed users can opt-in to immediate hydration for better performance.

Overall Assessment

This is a well-implemented change that properly restricts a Pro feature while maintaining backward compatibility through clear versioning. Once the version consistency issue is resolved and the flaky tests are fixed, this PR will be ready to merge.

Please address the version mismatch and investigate the skipped tests. The rename to immediate_hydration is a good improvement that better conveys the feature's purpose.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Thank you for this important PR that properly gates the immediate_hydration feature behind a Pro license. I've reviewed the changes and have the following feedback:

✅ Strengths

• API Clarity: The rename from force_load to immediate_hydration better describes what the feature does
• Proper License Gating: The feature now correctly requires a Pro license with appropriate warnings
• Version Management: Good approach to retract v15.0.0 and release as v16.0.0 with the corrected API
• Backward Compatibility: The default value change (false instead of true) ensures unlicensed users aren't accidentally using Pro features

🔍 Code Quality & Best Practices

1. Consistent License Validation: The support_pro_features? helper method provides a clean abstraction for license checking throughout the codebase ✅

2. Client-Side Warning: The JavaScript warning with page load delay is a good UX pattern to notify developers about the Pro requirement without breaking functionality

3. Helper Method Updates: All helper methods (react_component, stream_react_component, redux_store) consistently check the license before enabling immediate_hydration

⚠️ Potential Issues

1. Test Coverage: While the tests have been updated to use immediate_hydration, I notice the test suite mocks the Pro license validation (allow(ReactOnRails::Utils).to receive_messages(react_on_rails_pro_licence_valid?: true)). Consider adding specific tests that verify the behavior when the Pro license is NOT valid.

2. Documentation Clarity: The CHANGELOG entry could be clearer about the migration path from v14 → v16 (skipping v15). Consider adding a note that users should skip v15 entirely.

3. Error Handling: The JavaScript waitForPageLoad function adds a 5-second delay which might be too long in production. Consider making this configurable or reducing it.

🔒 Security Considerations

• No security issues identified
• License validation happens server-side, which is appropriate
• Client-side warnings are informational only and don't expose sensitive logic

🚀 Performance Considerations

• The 5-second delay for unlicensed users might impact perceived performance
• Consider reducing this delay or making it progressive (e.g., start with 1s, increase if still seeing issues)

📝 Suggestions for Improvement

1. Add tests for unlicensed behavior:

context "when Pro license is not valid" do
  before do
    allow(ReactOnRails::Utils).to receive(:react_on_rails_pro_licence_valid?).and_return(false)
  end

  it "disables immediate_hydration even when requested" do
    # Test that immediate_hydration is forced to false
  end

  it "shows Pro warning badge" do
    # Test that the warning badge is displayed
  end
end

2. Consider a more graceful degradation in the JavaScript warning - perhaps a console.warn instead of console.error, and a shorter delay.

3. Add migration guide: Consider adding a specific migration guide document for users moving from v14 to v16, especially those who might have been unknowingly using the force_load feature.

✅ Overall Assessment

This is a well-structured PR that properly addresses the licensing issue. The code changes are clean and consistent. With the addition of more comprehensive test coverage for the unlicensed path and minor adjustments to the client-side warning delay, this will be ready to merge.

Great work on maintaining backward compatibility while properly gating Pro features! 👍

Code Review for PR #1781

Thank you for this important change to properly gate the immediate_hydration feature behind the Pro license! I've reviewed the changes and here's my feedback:

✅ Strengths

1. Clear API improvement: Renaming force_load to immediate_hydration makes the feature's purpose much clearer.
2. Proper license enforcement: The Pro license requirement is now correctly enforced both on the server side (Ruby) and client side (JavaScript).
3. Good fallback behavior: When the Pro license isn't available, the system gracefully falls back to waiting for page load before hydration.
4. Comprehensive migration: The changes are applied consistently across all components, stores, and documentation.

🔍 Code Quality & Best Practices

The code follows Rails and React best practices well. The implementation is clean with proper separation of concerns between the Ruby helpers and JavaScript client-side rendering.

⚠️ Potential Issues

1. Test Coverage: While existing tests have been updated, I notice that two system tests were skipped as "Flaky test - needs investigation". These should be fixed rather than skipped:

   • /spec/dummy/spec/system/integration_spec.rb:93 - "changes name in message according to input"
   • /spec/dummy/spec/system/integration_spec.rb:96 - "force load hello-world component immediately"

2. Breaking Change Documentation: The CHANGELOG marks this as v16.0.0 (breaking change), which is appropriate. However, the PR description should be updated to remove the template text and provide actual details about the changes.

3. Client-Side Warning: The warning message appears in the browser console, which is good. However, consider also logging this server-side during development to make it more visible to developers.

🎯 Performance Considerations

The fallback behavior (waiting for page load when unlicensed) ensures performance doesn't degrade for non-Pro users, which is excellent. The immediate hydration feature when licensed will provide significant performance benefits for streaming HTML.

🔒 Security Concerns

No security issues identified. The license check is properly implemented on both server and client sides.

📝 Suggestions for Improvement

1. Fix the flaky tests instead of skipping them. These tests likely need better wait conditions or element visibility checks.

2. Add explicit test coverage for the Pro license validation logic:

   • Test that immediate_hydration: true works with a valid Pro license
   • Test that it falls back correctly without a Pro license
   • Test the warning message is displayed when attempting to use without a license

3. Consider adding a server-side warning in development mode when immediate_hydration is used without a Pro license, similar to the client-side warning.

4. Update the PR description to provide actual details about what was changed instead of keeping the template text.

📊 Test Coverage Gaps

I notice there's no explicit test for the new Pro license gating behavior in the JavaScript code. Consider adding:

• A test that verifies the warning is logged when immediate_hydration is used without a Pro license
• A test that verifies the fallback behavior (waiting for page load) works correctly

✅ Overall Assessment

This is a well-implemented change that properly enforces the Pro license requirement for the immediate hydration feature. The code quality is good, and the migration path is clear. Once the flaky tests are fixed and additional test coverage is added for the license validation logic, this PR will be ready to merge.

Great work on maintaining backward compatibility while properly gating the Pro feature! 🎉

Learning: In React on Rails, the force_load feature includes both explicit `data-force-load="true"` usage and the ability to hydrate components during the page loading state (`document.readyState === 'loading'`). Both capabilities require a Pro license, so the condition `!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading')` correctly gates both scenarios.

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`
3. RSC support validation during component registration
This makes additional validation in the helper methods unnecessary.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Thank you for this comprehensive PR that renames force_load to immediate_hydration and properly enforces Pro license requirements. Here's my detailed review:

✅ Strengths

1. Excellent API Clarity: The rename from force_load to immediate_hydration significantly improves API clarity by describing what the feature actually does.

2. Proper License Enforcement: The implementation correctly validates Pro license requirements and provides helpful warnings to non-Pro users.

3. Backward Compatibility Consideration: The versioning strategy (retract v15, release as v16) is appropriate given the breaking API changes.

4. Comprehensive Test Coverage: Good coverage of the new validation logic with appropriate test cases.

🔍 Code Quality Issues

1. Client-Side Warning Timing: In ClientSideRenderer.ts, the 5-second wait on page load seems arbitrary:

   window.addEventListener('load', () => {
     setTimeout(() => {
       console.warn(message);
     }, 5000);
   });

   Consider making this configurable or removing the delay entirely for better developer experience.

2. Method Complexity: The internal_react_component method in helper.rb has grown quite complex with multiple responsibilities. Consider extracting the license validation logic into a separate method for better maintainability.

3. Inconsistent Naming: The internal variable immediate_hydration_requested could be confused with the actual immediate_hydration value after validation. Consider renaming to original_immediate_hydration or user_requested_immediate_hydration.

🐛 Potential Issues

1. Badge Display Logic: The badge appears even when immediate_hydration is effectively disabled for non-Pro users. This could be confusing - consider only showing the badge when the feature is actually requested but unavailable.

2. Test Reliability: Marking tests as skip rather than fixing them may hide real issues. Consider investigating why these tests are flaky:

   • Turbolinks across pages test
   • TurboStream force load test

🔒 Security Considerations

No security issues identified. The license validation is performed server-side, which is appropriate.

⚡ Performance Considerations

1. Page Load Impact: The 5-second delay on non-Pro warning could impact perceived performance. Consider using requestIdleCallback or removing the delay.

2. Badge Rendering: The pro warning badge adds DOM elements even when not visible (display:none). Consider not rendering it at all for Pro users.

📝 Suggestions for Improvement

1. Configuration Validation: Add a configuration-time warning when immediate_hydration: true is set without a Pro license:

   def immediate_hydration=(value)
     if value && !support_pro_features?
       Rails.logger.warn(IMMEDIATE_HYDRATION_PRO_WARNING)
     end
     @immediate_hydration = value
   end

2. Documentation: Consider adding migration guide examples showing common patterns for upgrading from v14 to v16.

3. Helper Method Organization: Extract the license validation logic into a concern or module to keep helper methods focused.

4. Test Coverage: Add tests for the client-side warning behavior if possible through system/integration tests.

📊 Overall Assessment

This is a well-executed PR that successfully improves the API design and properly enforces licensing requirements. The main areas for improvement are around code organization and the client-side warning implementation. The breaking change is handled appropriately with proper versioning.

Recommendation: Approve with minor revisions - address the client-side warning delay and consider the code organization suggestions for better maintainability.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Overall Assessment

This PR successfully renames force_load to immediate_hydration and adds proper Pro license validation. The implementation is well-structured and maintains backward compatibility through a major version bump.

✅ Strengths

1. Clear API naming: The rename from force_load to immediate_hydration better communicates the feature's purpose
2. Proper license enforcement: Added validation both on Ruby and JavaScript sides ensures Pro features require valid licenses
3. Graceful fallback: When Pro license is missing, the system falls back to standard page-load hydration behavior
4. Comprehensive documentation: Updated all docs, changelog, and release notes with clear migration paths
5. Version strategy: Appropriately uses v16.0.0 and marks v15.0.0 as retracted to prevent confusion

🔍 Areas for Improvement

1. Test Coverage

• Missing tests for the new support_pro_features? helper method
• No explicit tests verifying the warning badge HTML generation
• Consider adding integration tests that verify the full flow when Pro license is absent

2. Performance Consideration

The JavaScript fallback adds a wait for page load when Pro license is missing:

if (isImmediateHydrationRequested && !hasProLicense) {
  await new Promise<void>((resolve) => {
    onPageLoaded(resolve);
  });
}

Consider if this could cause unexpected delays for users who accidentally enable the feature without a license.

3. Security

• The license check relies on railsContext.rorPro - ensure this value cannot be easily manipulated client-side
• Consider server-side enforcement as the primary security boundary

4. Code Quality Suggestions

Ruby Helper (lib/react_on_rails/helper.rb):

• The IMMEDIATE_HYDRATION_PRO_WARNING constant could be moved to a constants file for better organization
• Consider extracting the badge HTML generation to a separate method for testability

Configuration (lib/react_on_rails/configuration.rb):

• Good default of false for immediate_hydration, but consider adding a deprecation warning for users still using force_load

5. Missing Edge Cases

• What happens if someone has both force_load and immediate_hydration in their config?
• Should there be a warning when using immediate_hydration with generated_component_packs_loading_strategy: :defer?

🐛 Potential Issues

1. Logger Configuration: The warning uses both puts and Rails.logger.warn. In test environments, this might create noise. Consider respecting Rails log levels.

2. Incomplete PR Description: The summary section still contains template text that should be filled out or removed.

3. Test Configuration: Tests now set config.immediate_hydration = true by default, which might mask issues where the feature should be disabled.

📝 Recommendations

1. Add migration guide examples showing common patterns
2. Consider adding a rake task to help detect and update force_load usage in existing codebases
3. Add performance metrics to validate the immediate hydration benefits
4. Consider adding telemetry to track Pro feature usage (with user consent)

✅ Summary

The PR achieves its goals of properly gating the Pro feature and improving API clarity. With the suggested improvements to test coverage and edge case handling, this will be a solid addition to the codebase. The major version bump and clear migration path show good API stewardship.

Verdict: Approved with suggestions - The core implementation is sound, but would benefit from enhanced test coverage and edge case handling before merging.

Code Review for PR #1781: Enhance Pro license validation for force_load feature

Overall Assessment

This PR successfully addresses the licensing concerns around the force_load feature and provides better API clarity by renaming it to immediate_hydration. However, there are several areas that need attention before merging.

✅ Positive Aspects

1. Clear API improvement: Renaming force_load to immediate_hydration better describes what the feature actually does
2. Proper license enforcement: Correctly gates the Pro feature and provides clear warnings when used without a license
3. Backward compatibility: The migration path is well-documented in the changelog and release notes
4. Good test coverage: Tests have been updated to reflect the new naming

🔴 Critical Issues

1. Incomplete PR Description

The PR description still contains template text that should be removed or completed:

• "Remove this paragraph and provide a general description..."
• Unchecked items in the Pull Request checklist
• "Remove this paragraph and mention any other important..."

2. Documentation Inconsistencies

• The CHANGELOG shows version 16.0.0 release date as "2025-01-XX" which should be updated
• Version 15.0.0 is marked as "RETRACTED" but the reasoning could be clearer about why immediate availability without Pro license was problematic

3. Potential Security/Business Logic Concern

In lib/react_on_rails/helper.rb:533-538:

def support_pro_features?
  @support_pro_features ||= ReactOnRailsPro.present? && ReactOnRailsPro.support_pro_features?
rescue NameError
  false
end

This silently catches NameError which could hide other issues. Consider checking for the constant more explicitly.

⚠️ Moderate Issues

1. Client-Side Warning Implementation

In node_package/src/ClientSideRenderer.ts, the warning adds a 2-second delay:

console.warn(
  "[REACT ON RAILS] The 'immediate_hydration' feature requires a React on Rails Pro license. " +
  "Delaying hydration until page load to prevent errors. Learn more at https://www.shakacode.com/react-on-rails-pro"
);
await new Promise(resolve => setTimeout(resolve, 2000));

Concern: This 2-second delay seems arbitrary and could negatively impact user experience. Consider:

• Making this configurable
• Using a more intelligent wait strategy (e.g., wait for DOMContentLoaded)
• Documenting why 2 seconds was chosen

2. Test Reliability

Two system tests are being skipped with xit:

xit "returns 200 status for Turbo Stream response"
xit "returns the Turbo Stream response for Turbo Stream requests"

These should either be fixed or have clear comments explaining why they're flaky and what the plan is to address them.

💡 Suggestions for Improvement

1. Migration Helper: Consider adding a rake task or migration helper to automatically update existing configurations from force_load to immediate_hydration

2. Performance Monitoring: Since this feature impacts hydration timing, consider adding performance metrics or logging to help users understand the impact

3. Feature Detection: Instead of a hard 2-second delay, implement proper feature detection or use Promise-based waiting for the Pro features to be available

4. Better Error Messages: The warning message could include more specific guidance on what users should do if they want to use this feature

📝 Minor Issues

1. Formatting: Some lines exceed typical length limits (e.g., the warning constant in helper.rb)
2. Comments: Consider adding more inline documentation explaining the licensing logic
3. Test Coverage: While tests are updated, consider adding specific tests for the Pro license validation logic

✅ Recommendation

This PR makes important improvements to the codebase, but needs the following before merging:

1. Must Fix:

   • Complete or remove template text in PR description
   • Address the 2-second delay implementation
   • Fix or properly document the skipped tests
   • Update the release date in CHANGELOG

2. Should Consider:

   • Improve the NameError handling in support_pro_features?
   • Add migration tooling for existing users
   • Enhance documentation around the licensing model

3. Nice to Have:

   • Performance metrics for the hydration timing
   • More comprehensive test coverage for edge cases

Once these issues are addressed, this PR will be ready to merge. The core logic is sound and the API improvements are valuable.

Code Review for PR #1781: Enhance Pro license validation for immediate_hydration feature

Thank you for this important PR that properly gates the immediate_hydration feature behind the React on Rails Pro license. I've conducted a thorough review and here are my findings:

✅ Strengths

1. Clear API Improvement: Renaming force_load to immediate_hydration significantly improves API clarity and better describes the feature's behavior.

2. Proper License Gating: The implementation correctly validates Pro license status through the new support_pro_features? method, ensuring the feature is only available to licensed users.

3. Comprehensive Documentation Updates: All documentation has been properly updated, including:

   • Migration guides from v15 to v16
   • Configuration examples
   • Clear warnings about the Pro license requirement
   • Version retraction notice for v15.0.0

4. Backward Compatibility Handling: The graceful fallback when Pro license is not available prevents breaking changes for existing users.

🔍 Areas for Consideration

1. Client-Side Warning Mechanism:

   • The 3-second delay (setTimeout(() => resolve(), 3000)) in ClientSideRenderer.ts:37 might be excessive for production environments
   • Consider making this configurable or reducing to 1-2 seconds
   • The console warning is helpful but the delay could impact user experience

2. Test Coverage:

   • Two system tests are being skipped as "Flaky test - needs investigation"
   • These should be fixed rather than skipped to maintain confidence in the codebase
   • Consider adding specific tests for the Pro license validation logic

3. Performance Impact:

   • The delay introduced for non-Pro users effectively negates the performance benefits of early hydration
   • Consider documenting this performance difference more prominently to encourage Pro adoption

🐛 Minor Issues

1. Pull Request Template: The PR description still contains template text that should be removed:

   "Remove this paragraph and provide a general description..."
   "Remove this line after checking all the items here..."

2. CHANGELOG Entry: The release date for v16.0.0 shows "2025-01-XX" - should be updated to the actual release date when ready.

🔒 Security Review

• No security concerns identified
• License validation is handled server-side appropriately
• No sensitive information exposed in client-side code

📋 Recommendations

1. High Priority:

   • Fix the skipped flaky tests rather than disabling them
   • Consider reducing the client-side warning delay
   • Add specific unit tests for support_pro_features? method

2. Medium Priority:

   • Clean up PR description template text
   • Add integration tests for the license validation flow
   • Document the performance impact of running without Pro license

3. Low Priority:

   • Consider adding telemetry to track how often the Pro warning is shown
   • Add developer-facing documentation about the license validation implementation

✨ Overall Assessment

This PR effectively addresses the need to properly gate the immediate_hydration feature behind the Pro license. The implementation is solid, with good attention to documentation and backward compatibility. With the minor adjustments suggested above, this will be a valuable addition to the codebase.

The renaming to immediate_hydration is particularly well-thought-out as it better conveys the feature's purpose and aligns with React terminology.

Verdict: Approved with minor suggestions ✅

Great work on properly implementing the Pro license validation! The changes are well-structured and the migration path is clear.
