Skip generate_packs when shakapacker precompile hook configured #1861
Conversation
This change prevents react_on_rails from running generate_packs twice when shakapacker has a precompile hook configured that already runs it. Changes: - Add PackerUtils.shakapacker_precompile_hook_configured? to detect hook - Skip generate_packs in assets:precompile if hook is configured - Skip generate_packs in bin/dev if hook is configured - Add comprehensive test coverage for new behavior This ensures generate_packs runs only once during both: - Production asset precompilation (assets:precompile) - Development server startup (bin/dev) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
WalkthroughAdds detection of a Shakapacker precompile hook and conditionally skips invoking react_on_rails:generate_packs during precompile and in the dev PackGenerator. Introduces PackerUtils.shakapacker_precompile_hook_configured? and updates specs to cover both the new conditional flow and utility behavior. Changes

Code Review - PR #1861: Skip generate_packs when shakapacker precompile hook configuredOverall AssessmentStatus: Approved with minor suggestions This is a well-crafted PR that solves a real problem (duplicate pack generation) with a clean, testable solution. The code quality is excellent, and the test coverage is comprehensive. Strengths1. Excellent Problem Definition
2. Clean Implementation
3. Comprehensive Test Coverage
4. Code Style
Suggestions for Improvement1. Configuration Caching (Minor Performance)lib/react_on_rails/packer_utils.rb:168 Consider caching the hook check since config does not change at runtime. This method may be called multiple times during precompile, and caching would avoid repeated YAML parsing. However, this is optional - the current implementation is fine for most use cases. Caching adds complexity and makes testing slightly harder. Only worth it if performance profiling shows it is a bottleneck. 2. String Matching Robustness (Low Risk)lib/react_on_rails/packer_utils.rb:177 Current implementation uses simple .include? check which could theoretically match strings like "not_react_on_rails:generate_packs" (unlikely but possible). A regex with word boundary would be more precise: Array(hooks).any? { |hook| hook.to_s.match?(/react_on_rails:generate_packs(?:\s|$)/) } Verdict: Current implementation is probably fine given the context, but worth considering. 3. Logging Consistency (Minor UX)lib/react_on_rails/configuration.rb:250-253 The precompile task silently skips without any log output. Consider adding logging to help users understand why pack generation was skipped during debugging. Security ConsiderationsNo security concerns identified:
Performance ConsiderationsPerformance impact is minimal:
Potential Issues1. Edge Case: Multiple Hooks with Mixed ContentThe current implementation correctly handles arrays of hooks. Tests cover this - good! 2. Shakapacker Version CompatibilityThe PR assumes ::Shakapacker.config.send(:data) is available. This is a private method call (using send), which could break in future versions. Risk Level: Low (Shakapacker maintains good backward compatibility) Test Coverage AnalysisExcellent test coverage. Tests cover:
Suggestion: Consider adding one test for empty string hook to ensure robustness. DocumentationGood documentation in PR description. Consider adding:
ConclusionThis PR demonstrates excellent software engineering practices:
Recommendation: Merge after considering the minor suggestions above. The suggestions are optional improvements - the PR is production-ready as-is. Checklist VerificationFrom CLAUDE.md requirements:

PR Review: Skip generate_packs when shakapacker precompile hook configuredOverall AssessmentThis is a well-implemented PR that solves a real problem (duplicate pack generation) with a clean, defensive approach. The code quality is high, test coverage is comprehensive, and the implementation follows the repository conventions. Strengths
Code QualityThe new shakapacker_precompile_hook_configured? method (lib/react_on_rails/packer_utils.rb:167-183) is well-structured with early returns, safe navigation with dig, and Array() wrapper for flexible input handling. Minor consideration: Using .send(:data) to access private data is slightly fragile, but acceptable given graceful failure handling and consistency with line 109. TestingExcellent coverage in packer_utils_spec.rb and pack_generator_spec.rb covering all scenarios including edge cases and error handling. Performance & SecurityNo concerns - configuration checks are infrequent, no user input execution, proper exception handling. Potential Issues
RecommendationsRequired: None - ready to merge Optional:

🔍 Potential Issues & Suggestions1. String Matching Could Be More Robust (Minor)The current string matching uses include? which could have false positives with comments. Consider using regex with word boundaries for more precise matching. 2. Missing Logging in Configuration.rb (Minor)In lib/react_on_rails/configuration.rb:247-253, the skip happens silently. Consider adding logging when skipping for consistency with pack_generator.rb. 3. Method Uses Private API (Minor Security/Stability)The method accesses Shakapacker's private API via .send(:data). Consider:
🧪 Test Coverage: Excellent ✅Comprehensive coverage including hook configured/not configured, verbose/quiet modes, error handling, and edge cases. No additional tests needed. 🔒 Security: No Concerns ✅Code only reads configuration, has proper error handling, no injection vulnerabilities, and fails safely. ⚡ Performance: No Concerns ✅Runs once per precompile with simple hash lookups and string checks. 🎬 RecommendationsBefore merging:

|
Potential Improvements1. String Matching Could Be More Robust (packer_utils.rb:177) Current code uses .include? which would match false positives like comments or echo statements. Suggestion: Consider a more precise regex match with word boundaries to reduce false positives. 2. Configuration Access Pattern (packer_utils.rb:172) Using send(:data) to access a private method suggests this might be brittle if Shakapacker changes its internal API. Suggestions:
3. Missing Configuration Example in Tests The tests mock the configuration but don't show what real shakapacker.yml would look like. Consider adding a comment in the test file showing the actual YAML structure users would write. |
Test Coverage AnalysisExcellent coverage:
Potential additions (optional, low priority):
Security & PerformanceSecurity: No concerns identified. The code doesn't execute user input, only reads configuration, and fails safely with rescue StandardError. Performance: Negligible impact. Config read is cached by Shakapacker, string check is O(n) where n = number of hooks (typically 1-3), and only runs during precompile/dev startup (not request path). |

Minor Suggestions1. Consider Logging in Silent Failure Mode In packer_utils.rb:177, when an exception occurs, it silently returns false. While this is the right behavior, consider logging the error for debugging. 2. DRY Opportunity in Tests The pack_generator_spec.rb tests could extract the shared command strings to reduce duplication. 3. Missing Edge Case Test Consider adding a test for when config_data is nil (not just when hooks are missing). Potential IssuesNone identified - The implementation handles edge cases well. Performance ConsiderationsCaching Opportunity: The shakapacker_precompile_hook_configured? method reads the config file on every call. Consider memoizing the result. Impact: Low - This method is called infrequently (only during asset precompile and bin/dev startup), so the performance gain would be minimal. However, it would prevent redundant file reads.

When shakapacker supports precompile hooks (upcoming feature), users can configure:
yaml
config/shakapacker.yml
hooks:
precompile: "bundle exec rake react_on_rails:generate_packs"
Without this PR,
generate_packswould run twice:assets:precompileorbin/devThis PR ensures it only runs once by detecting the hook configuration.
