Refactor: Extract JS dependency management into shared module #2051
Conversation
This refactoring addresses duplicate code between BaseGenerator and InstallGenerator by extracting JavaScript dependency management into a shared JsDependencyManager module. Key improvements: - Eliminates ~270 lines of duplicated code - Centralizes dependency definitions in frozen constants - Removes Babel dependencies (now managed by Shakapacker) - Changes default transpiler to SWC in shakapacker.yml - Adds comprehensive test coverage for the new module - Simplifies dependency installation flow The module leverages package_json gem (always available via Shakapacker) for reliable cross-platform package management. Breaking change: Default webpack_loader changed from 'babel' to 'swc' in generated shakapacker.yml for better performance.

Fix Rspack transpiler key mismatch
We now emit javascript_transpiler in the template, but configure_rspack_in_shakapacker (see lib/generators/react_on_rails/base_generator.rb, Line 310) still mutates webpack_loader. If someone reruns the generator with --rspack after switching the YAML to "babel", the helper leaves javascript_transpiler untouched, so Shakapacker continues to expect Babel even though we removed the Babel deps in this refactor. The resulting build blows up under Rspack.
Please flip the helper to update the new key (and fall back to the legacy one for older configs), e.g.:
config["default"] ||= {}
- config["default"]["assets_bundler"] = "rspack"
- config["default"]["webpack_loader"] = "swc"
+ config["default"]["assets_bundler"] = "rspack"
+ if config["default"].key?("javascript_transpiler")
+ config["default"]["javascript_transpiler"] = "swc"
+ else
+ config["default"]["webpack_loader"] = "swc"
+ endCommittable suggestion skipped: line range outside the PR's diff.

In lib/generators/react_on_rails/base_generator.rb around line 310 (changes
affect lib/generators/react_on_rails/templates/base/base/config/shakapacker.yml
lines 39-47), the configure_rspack_in_shakapacker helper currently mutates the
legacy webpack_loader key only; update the helper to prefer and modify the new
javascript_transpiler key (set it to "swc" or the appropriate value when
enabling rspack) and ensure assets_bundler is set to "rspack", and keep a
fallback to update the legacy webpack_loader key for older configs.
Code Review: PR #2051 - JsDependencyManager RefactoringThanks for this excellent refactoring! This PR successfully eliminates ~270 lines of duplicated code and centralizes dependency management. The overall direction is solid, but I've identified several issues that should be addressed before merging. 🔴 Critical Issues (Must Fix)1. Inconsistent Exception Handling StrategyProblem: The module has inconsistent error handling that could crash the generator unexpectedly. # In js_dependency_manager.rb - Methods raise exceptions:
def add_react_dependencies
if add_js_dependencies_batch(REACT_DEPENDENCIES)
@added_dependencies_to_package_json = true
else
raise "Failed to add React dependencies..."
end
end
# But install_js_dependencies catches and handles errors gracefully:
def install_js_dependencies
package_json.manager.install
true
rescue StandardError => e
GeneratorMessages.add_warning(...)
false
endImpact: If Recommendation: Use consistent error handling throughout:
2. Inadequate Test CoverageProblem: The test file Missing coverage:
Recommendation: Create describe ReactOnRails::Generators::JsDependencyManager do
describe "constants" do
it "defines frozen dependency arrays" do
expect(described_class::REACT_DEPENDENCIES).to be_frozen
end
it "does not include Babel presets in React dependencies" do
expect(described_class::REACT_DEPENDENCIES).not_to include("@babel/preset-react")
end
end
describe "#add_rspack_dependencies" do
context "when rspack option is true" do
# Test Rspack deps are added
end
end
# Test error scenarios, TypeScript deps, etc.
end3. Breaking Change in shakapacker.yml Needs DocumentationProblem: The configuration key changed from # Old (generated in previous versions)
webpack_loader: 'babel'
# New (generated now)
javascript_transpiler: "swc"
assets_bundler: "webpack"Questions:
Recommendation:
🟡 Medium Issues (Should Fix)4. Babel Dependencies Removed But Templates Still Reference ThemProblem: The spec/dummy/babel.config.js file references packages that are no longer installed: // spec/dummy/babel.config.js:12
'@babel/preset-react',
// spec/dummy/babel.config.js:23
'babel-plugin-transform-react-remove-prop-types',These were removed from
Recommendation:
5. Redundant Instance Variable TrackingProblem: The code maintains def setup_js_dependencies
@added_dependencies_to_package_json = false unless defined?(...)
add_js_dependencies
# Always run install regardless of the flag above
install_js_dependencies
endEvery method sets this flag to Recommendation: Remove the instance variable entirely or document why it's needed for future use. 6. Performance Concern: Always Running InstallProblem: The old # Old code
install_js_dependencies if @added_dependencies_to_package_json && \!@ran_direct_installsThe new code always runs install. While the comment claims package_json's install is idempotent, there's no benchmarking data. Questions:
Recommendation: Benchmark before/after on slow connections to verify no regression. 🔵 Low Priority Issues (Nice to Fix)7. Inconsistent Method Naming
8. Missing Null SafetyUse safe navigation operator for optional chaining: add_rspack_dependencies if respond_to?(:options) && options&.rspack?9. Unusual Instance Variable Initialization Pattern# Current
@added_dependencies_to_package_json = false unless defined?(...)
# Standard Ruby pattern
@added_dependencies_to_package_json ||= false10. YAML Quote Style InconsistencyNew config uses double quotes while other YAML files may use single quotes. Check consistency across the file. ✅ Positive Aspects
Overall AssessmentThis is a solid refactoring that significantly improves code maintainability. The core idea and execution are excellent. However, the critical issues with exception handling, test coverage, and breaking changes should be addressed before merging. Recommendation: Request Changes Action Items Before Merge:
Great work on this refactoring! Looking forward to seeing these issues addressed. 🚀 |
The test was failing because the mock PackageManager double only stubbed the 'install' method, but the actual code calls 'pj.manager.add(packages_array)' in add_js_dependency. This commit adds the 'add' method to the mock's allowed methods, allowing the test to properly verify that package_json gem methods are used instead of system() commands for dependency installation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Comprehensive Code Review: PR #2051Executive SummaryThis PR successfully extracts approximately 270 lines of duplicated code into a well-designed 🔴 Critical Issues (Must Fix)1. Bug: Inconsistent Config Keys in Rspack ConfigurationLocation: The template

endFix Required: Update to match the new naming convention. 2. Missing Unit Tests for JsDependencyManagerLocation: Only The new module lacks dedicated unit tests. Current tests only verify integration scenarios (message deduplication). Need tests for:
Recommendation: Add 3. Changed Error Handling Behavior (Undocumented Breaking Change)Location: Before: Generators gracefully degraded with warnings when package installation failed # Old behavior
success = system("npm", "install", *react_deps)
handle_npm_failure("React dependencies", react_deps) unless success # Warning only
# New behavior
else
raise "Failed to add React dependencies..." # ❌ Hard failure
endImpact: This could break existing workflows where partial failures were acceptable (e.g., offline development). Recommendation: Either preserve graceful degradation pattern or explicitly document this breaking change in the PR description and CHANGELOG. 🟡 Important Issues (Should Fix)4. Babel Config Generation MismatchLocation: Issue: The default transpiler changed to SWC, but base_files = %w[babel.config.js # Still copied even for SWC users!

Recommendation: Make 5. Unused Instance VariableLocation: @added_dependencies_to_package_json = false unless defined?(@added_dependencies_to_package_json)This variable is set throughout the module but never read. The old code used it to conditionally run install, but the new module always runs install. Recommendation: Remove it entirely or document why it's preserved for backward compatibility. 6. Behavior Change: Installation Now Always RunsLocation: Before: install_js_dependencies if @added_dependencies_to_package_json && !@ran_direct_installsAfter: setup_js_dependencies # Always calls install_js_dependenciesWhile the comment explains this is "safe because package_json gem's install is idempotent," this changes behavior and could add 1-2 seconds to generator execution. Recommendation: Document this behavior change in the PR description. 7. Unrelated Method RenameLocation: - def update_gitignore_for_generated_bundles

Example of Great Documentation# Note: @babel/preset-react and babel plugins are NOT included here because:
# - Shakapacker handles JavaScript transpiler configuration (babel, swc, or esbuild)

1-65: Excellent test coverage for message deduplication.The post-install message tests are well-structured and directly address the PR objectives. The mocking strategy properly isolates the generators from file system dependencies, and the tests verify both the uniqueness of success messages and the presence of expected content for both Redux and non-Redux installations.
112-140: Robust verification of the shared module refactoring.The method ownership verification using
instance_method(method).owneris an excellent approach to ensure that methods are truly shared via theJsDependencyManagermodule and not duplicated in each generator. This directly validates one of the core objectives of the refactoring.
1-141: Note: Static analysis false positives can be safely ignored.The ast-grep warnings about "hardcoded RSA passphrases" on lines 33-36 and 51-54 are false positives—these are RSpec expectation messages explaining test failures, not security credentials. Overall, this test file provides comprehensive coverage of the message deduplication objectives and validates the refactoring work effectively.
Code Review FeedbackThank you for this well-structured refactoring! This is a significant improvement that eliminates ~270 lines of code duplication. Here's my detailed review: ✅ Strengths1. Excellent Code Organization
2. Smart Architectural Decisions
3. Breaking Change Handling
4. Test Coverage
🔍 Potential Issues1. Breaking Change: Removal of Babel Dependencies The new REACT_DEPENDENCIES removes @babel/preset-react, babel-plugin-transform-react-remove-prop-types, and babel-plugin-macros. Users who configure javascript_transpiler: babel will be missing these critical packages. Recommendation: Consider conditionally adding these when Babel is configured, or document the migration clearly in CHANGELOG.md 2.

Comprehensive Code ReviewThank you for this excellent refactoring! The extraction of ~270 lines of duplicated code into a shared module is well-executed with great documentation. However, I've identified several critical issues that should be addressed before merging. Critical Issues (Must Fix)1. 🔴 Inconsistent Error Handling PatternLocation: Problem: The code has conflicting error handling strategies:
This makes the graceful error handling pointless - if Recommendation: Either let exceptions bubble up from Suggested fix: def setup_js_dependencies

🧹 Nitpick comments (6)
spec/react_on_rails/generators/message_deduplication_spec.rb (2)
12-43: Post‑install message coverage looks good; consider tightening duplicate checksThese examples nicely assert that the success banner is emitted exactly once and that the key sections (“📋 QUICK START:”, “✨ KEY FEATURES:”) are present.
If the original bug involved duplication of the whole post‑install block (not just the headline), you might optionally also count occurrences of “📋 QUICK START:” and “✨ KEY FEATURES:” to ensure they are each emitted once as well. That would guard against future regressions where the body gets duplicated but the headline does not.
67-107: Good isolation of package_json‑based install pathThe “NPM install execution” example cleanly verifies that
setup_js_dependenciesuses thepackage_jsonmanager and does not fall back tosystemwhen the gem is available, which directly exercises the new flow.One small optional improvement: the initial
receive_messagessetsadd_npm_dependencies: falseand the innerbeforeimmediately overrides it withadd_npm_dependencies: true, so the first stub isn’t needed anymore and can be dropped to reduce noise.lib/generators/react_on_rails/js_dependency_manager.rb (2)
84-95: Ensure TypeScript dependencies are actually wired into the setup flowThis module defines
TYPESCRIPT_DEPENDENCIESandadd_typescript_dependencies, butadd_js_dependenciescurrently only calls:
add_react_on_rails_packageadd_react_dependenciesadd_css_dependenciesadd_rspack_dependencies(whenoptions.rspack?)add_dev_dependenciesThere’s no call to
add_typescript_dependencieshere. If the intent is for this module to own all JS dependency installation, it would be more consistent (and less error‑prone) to gate TypeScript installation here as well, e.g.:def add_js_dependencies add_react_on_rails_package add_react_dependencies add_css_dependencies + add_typescript_dependencies if respond_to?(:options) && options&.typescript? # Rspack dependencies are only added when --rspack flag is used add_rspack_dependencies if respond_to?(:options) && options&.rspack? # Dev dependencies vary based on bundler choice add_dev_dependencies endIf
InstallGenerator(or another caller) already invokesadd_typescript_dependenciesdirectly behind--typescript, just ensure that’s the single path so TypeScript installs can’t be accidentally skipped.Also applies to: 109-117
119-148: Simplify error handling aroundadd_react_on_rails_package
add_react_on_rails_packagewrapsadd_packageand then also rescuesStandardError, butadd_packageitself already rescuesStandardErrorand converts failures intofalse. In practice that means errors frompj.manager.addwill always surface via the"Failed to add react-on-rails package."warning, and the"Error adding react-on-rails package: #{e.message}"branch is effectively unreachable.You could either:
- Let
add_packagepropagate exceptions (and rely on therescuehere), or- Drop the outer
rescueand keep the simpler “failed” warning path,to reduce duplication and make it clearer where errors are actually logged.
Also applies to: 262-278
spec/react_on_rails/generators/js_dependency_manager_spec.rb (2)
47-55:warnings/errorshelpers assume a specific message prefixThese helpers filter
GeneratorMessages.outputby checking whetherto_sincludes"WARNING"or"ERROR". That’s fine ifGeneratorMessages.add_warning/add_errorconsistently prefixes messages that way, but it’s a tight coupling: if those methods ever switch to a different label or rely solely on the leading “⚠️ ” glyph, these specs will silently stop seeing warnings.If you want the tests to be more robust, consider either:
- Adding dedicated
GeneratorMessages.warnings/errorsaccessors and using those here, or- Matching on a phrase that comes from the JsDependencyManager messages themselves (e.g.,
"Failed to add React dependencies"), rather than the generic prefix.
217-225: Tighten the failure scenario foradd_react_on_rails_packageIn this example you stub both
mock_manager.addand setinstance.package_json = nil. Becauseadd_packageimmediately returnsfalsewhenpackage_jsonisnil, themock_managerstub is never exercised; the warning is driven solely by the nil package_json case.To make the intent clearer, you could either:
- Drop the
allow(mock_manager).to receive(:add).and_return(false)here and treat this as the “no package_json” path, or- Keep
package_jsonset and rely onmock_manager.addreturningfalseto simulate an API-level failure.Either way, the test will still validate that a warning is emitted when adding the package fails, but with less ambiguity about which failure path you’re targeting.

3-121: RBS signatures align with the Ruby moduleThe constant and method signatures here match the implementation in
lib/generators/react_on_rails/js_dependency_manager.rb(including boolean returns foradd_package,add_packages, andinstall_js_dependencies, and void for the orchestration helpers). This should give Steep/Sorbet a precise view of the new module without over‑constraining callers.CHANGELOG.md (1)
46-52: ****The flagged CHANGELOG entries are not contradictory. The "Shakapacker 9.0.0 Upgrade" entry (PR 1904) documents the decision to configure Babel specifically for that application upgrade due to SWC's PropTypes handling issues. The "Removed Babel Dependency Installation" entry (PR 2051) is a separate changelog item describing a later decision to stop installing Babel in the generator and rely on SWC as the default for new applications. These describe different contexts (upgrading existing apps vs. generating new ones) and different PRs, so no clarification or consolidation is needed.
Likely an incorrect or invalid review comment.
Address code review suggestions:
- Expand module documentation to explain graceful degradation philosophy
in detail, including specific failure scenarios (network, permissions,
package_json gem states)
- Add comprehensive tests for graceful degradation:
* Verify setup_js_dependencies completes without raising when all
package operations fail
* Verify completion when install fails but add succeeds
* Ensure warnings are generated but no errors that crash generators
- Improve add_package method documentation to clarify that exact: true
flag ensures version pinning aligns with gem version, preventing
mismatches between Ruby gem and NPM package
These changes improve code documentation and test coverage without
changing functionality. All 38 tests pass.

The implementation is solid with comprehensive test coverage and excellent documentation. Strengths 💪Architecture & Design
Code Quality
Breaking Changes Handled Well
Potential Issues & Suggestions 🔍1. Error Handling - Minor ConcernLocation: The def add_package(package, dev: false)
# ...
begin
# ...
rescue StandardError
return false # Caught here
end
end
def add_react_on_rails_package
return if add_package(react_on_rails_pkg)
# Warning added here if false returned
rescue StandardError => e
# Also caught here - might be unreachable?
GeneratorMessages.add_warning(...)
endImpact: Low - The outer rescue blocks in calling methods may be unreachable since Suggestion: Consider simplifying to single-level error handling if the inner rescue always catches everything. 2. Dependency Version ControlLocation: All dependencies except
Example: REACT_DEPENDENCIES = %w[
react # Could install any version
react-dom # Could install any version
prop-types
].freezeImpact: Medium - Users could get different dependency versions depending on when they run the generator. Suggestion: Consider adding version constraints to critical dependencies: REACT_DEPENDENCIES = %w[
react@^18.0.0
react-dom@^18.0.0
prop-types
].freezeHowever, this may be intentional to allow users flexibility. If so, document the reasoning. 3. Test Mock VerificationLocation: Tests use unverified doubles which could mask interface changes: # rubocop:disable RSpec/VerifiedDoubles
let(:mock_manager) { double("PackageManager", install: true, add: true) }
let(:mock_package_json) { double("PackageJson", manager: mock_manager) }
# rubocop:enable RSpec/VerifiedDoublesImpact: Low - Tests could pass even if the actual package_json gem API changes. Suggestion: Consider using verified doubles or instance_double if the package_json gem supports it: let(:mock_manager) { instance_double("PackageJson::Manager", install: true, add: true) }4. Missing TypeScript Integration TestLocation: Test coverage gap The Impact: Low - Unit tests exist, but integration coverage would be more complete. Suggestion: Add test in context "with TypeScript installation" do
it "adds TypeScript dependencies" do
run_generator_test_with_args(%w[--typescript], package_json: true)
# Verify TypeScript packages were added
end
end5. Rspack Dependency CompletenessLocation: When using Rspack, the generator adds Rspack-specific dependencies but still adds Webpack CSS dependencies (CSS_DEPENDENCIES). This might be intentional, but could lead to unused Webpack packages in Rspack projects. Impact: Low - Extra dependencies consume disk space but don't break functionality. Suggestion: Clarify whether CSS_DEPENDENCIES are needed for both Webpack and Rspack, or if Rspack needs its own CSS dependency set. Security Considerations 🔒✅ No security concerns identified
Performance Considerations ⚡✅ Well optimized
Minor observation: The Test Coverage 🧪Excellent coverage (387 lines of tests): ✅ All public methods tested One gap: Missing integration test for TypeScript flag (see #4 above) Documentation 📚Outstanding documentation: ✅ Comprehensive module-level docs The documentation explaining why Babel presets were removed is particularly helpful for users upgrading.
