Use exact option in package_json gem for installing dependencies #1939
Conversation
The package_json gem (v0.2.0) now supports an 'exact' parameter in the add method to install packages with exact versions (no ^ or ~ prefix). This change updates the add_npm_dependencies helper method to use exact: true when adding both regular and dev dependencies. This ensures that React on Rails generators install npm packages with exact version specifications, consistent with the project's requirement for strict version matching between the gem and npm packages. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Add test coverage for the add_npm_dependencies method to verify: - Regular dependencies are added with exact: true parameter - Dev dependencies are added with type: :dev and exact: true parameters - Error handling returns false and prints appropriate warnings - package_json method properly memoizes results and handles errors These tests ensure the new exact option from package_json gem v0.2.0 is properly utilized when adding npm dependencies during generation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
PR Review: Use exact option in package_json gem for installing dependenciesSummaryThis PR adds the Code Quality ✅Strengths
Test Coverage ✅The new test file (
Note on line 46-48: There's a subtle issue where the test calls expect { add_npm_dependencies(packages) }.to output(/Warning: Could not add packages/).to_stdout

According to CLAUDE.md, changelog updates should be for "user-visible changes only". Since this is an implementation detail that improves correctness (exact versions), it may warrant a changelog entry under "Enhancements" or "Bug Fixes".

Overall Assessment: ✅ Approve with minor changesThis is a solid, well-tested improvement that enhances version control reliability. The primary blocker is adding the dependency version constraint to the gemspec. Once that's addressed, this should be safe to merge. Estimated Risk: Low (with gemspec update) / Medium (without gemspec update) Great work on the comprehensive test coverage! 🎉 |

1-109: Comprehensive test coverage with one optional refactor.The test suite thoroughly validates the new
exact: trueparameter behavior for both regular and dev dependencies, as well as error handling and memoization. All test expectations correctly match the updated production code.Consider refactoring lines 47-50 and 104-105 to capture the return value in a single method call rather than calling the method twice:
For lines 46-51:
- allow(mock_manager).to receive(:add).and_raise(StandardError, "Installation failed") - expect { add_npm_dependencies(packages) }.to output(/Warning: Could not add packages/).to_stdout - - result = add_npm_dependencies(packages) + allow(mock_manager).to receive(:add).and_raise(StandardError, "Installation failed") + + result = nil + expect { result = add_npm_dependencies(packages) }.to output(/Warning: Could not add packages/).to_stdout expect(result).to be falseFor lines 103-106:
- it "returns nil and prints a warning" do - expect { package_json }.to output(/Warning: Could not read package\.json/).to_stdout - expect(package_json).to be_nil + it "returns nil and prints a warning" do + result = nil + expect { result = package_json }.to output(/Warning: Could not read package\.json/).to_stdout + expect(result).to be_nil endThis avoids redundant method calls and makes the test intent clearer.
