From 3905a07bb37a8bc7665fd33f91208f6d466ba39b Mon Sep 17 00:00:00 2001 From: Justin Gordon Date: Tue, 4 Nov 2025 18:25:41 -1000 Subject: [PATCH 1/3] Fix CI failure by skipping version validation during generator runtime MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The strict version validation added in #1881 runs during Rails initialization via an after_initialize hook. However, when running `rails generate react_on_rails:install`, the npm packages haven't been installed yet, causing the validation to fail with: "No React on Rails npm package is installed." This fix adds a check to skip validation when running Rails generators (detected by checking if ARGV.first is "generate" or "g"). The generator will install packages during its execution, so validation at initialization time is not appropriate. This allows CI to successfully run example generation tasks without errors. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- lib/react_on_rails/engine.rb | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/lib/react_on_rails/engine.rb b/lib/react_on_rails/engine.rb index 8e4e6d859c..42bbf3136e 100644 --- a/lib/react_on_rails/engine.rb +++ b/lib/react_on_rails/engine.rb @@ -6,9 +6,13 @@ module ReactOnRails class Engine < ::Rails::Engine # Validate package versions and compatibility on Rails startup # This ensures the application fails fast if versions don't match or packages are misconfigured - # Skip validation during installation tasks (e.g., shakapacker:install) + # Skip validation during installation tasks (e.g., shakapacker:install) or generator runtime initializer "react_on_rails.validate_version_and_package_compatibility" do config.after_initialize do + # Skip validation when running Rails generators - they will install packages during execution + running_generator = ARGV.first == "generate" || ARGV.first == "g" + next if running_generator + # Skip validation if package.json doesn't exist yet (during initial setup) package_json = VersionChecker::NodePackageVersion.package_json_path next unless File.exist?(package_json) From ae9062814ac93538441542721df5b60665ebd11c Mon Sep 17 00:00:00 2001 From: Justin Gordon Date: Tue, 4 Nov 2025 18:41:53 -1000 Subject: [PATCH 2/3] Address code review feedback: improve validation skip logic MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Improvements based on code review: 1. **Nil-safe ARGV check**: Use safe navigation operator and check for empty ARGV - Prevents errors when ARGV is empty or nil - More defensive against edge cases 2. **Refactored to extract methods**: Created testable class methods - skip_version_validation?() - main entry point - running_generator?() - checks if running Rails generator - package_json_missing?() - checks if package.json exists - Improves testability and code clarity 3. **Added debug logging**: Log when validation is skipped - "Skipping validation - package.json not found" - "Skipping validation during generator runtime" - Helps debugging and understanding behavior 4. **Optimized check order**: Check package.json existence first - File existence check is cheaper than ARGV inspection - Handles more cases (initial setup, generators, etc.) 5. **Comprehensive test coverage**: Added 15 test cases - Tests for package.json missing scenarios - Tests for generator detection (both "generate" and "g") - Tests for edge cases (empty ARGV, other commands) - Tests for each helper method All tests passing, RuboCop clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- lib/react_on_rails/engine.rb | 38 +++++-- spec/react_on_rails/engine_spec.rb | 160 +++++++++++++++++++++++++++++ 2 files changed, 191 insertions(+), 7 deletions(-) create mode 100644 spec/react_on_rails/engine_spec.rb diff --git a/lib/react_on_rails/engine.rb b/lib/react_on_rails/engine.rb index 42bbf3136e..d63c0e0b02 100644 --- a/lib/react_on_rails/engine.rb +++ b/lib/react_on_rails/engine.rb @@ -9,13 +9,7 @@ class Engine < ::Rails::Engine # Skip validation during installation tasks (e.g., shakapacker:install) or generator runtime initializer "react_on_rails.validate_version_and_package_compatibility" do config.after_initialize do - # Skip validation when running Rails generators - they will install packages during execution - running_generator = ARGV.first == "generate" || ARGV.first == "g" - next if running_generator - - # Skip validation if package.json doesn't exist yet (during initial setup) - package_json = VersionChecker::NodePackageVersion.package_json_path - next unless File.exist?(package_json) + next if skip_version_validation?
