From e857e7abbe897122bef8459cb6166d3fd62a9205 Mon Sep 17 00:00:00 2001 From: Justin Gordon Date: Tue, 16 Sep 2025 22:57:23 -1000 Subject: [PATCH 01/24] Add react_on_rails:doctor generator for setup diagnostics MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit introduces a comprehensive diagnostic command that helps users validate their React on Rails setup and identify configuration issues. Features: - Environment validation (Node.js, package managers, Git status) - Package validation (gem/npm versions, Shakapacker configuration) - Dependencies checking (React, Babel presets) - Rails integration validation (initializers, routes, controllers) - Webpack configuration analysis - Development environment checks (bundles, Procfiles, .gitignore) The doctor command provides colored output with detailed error messages, warnings, and success confirmations. It supports --verbose mode for detailed output and has proper exit codes for CI/automation use. The implementation includes: - SystemChecker module with reusable validation logic - DoctorGenerator with comprehensive checks and reporting - Complete test coverage for both components - Documentation updates in README and CHANGELOG Usage: rails generate react_on_rails:doctor [--verbose] šŸ¤– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CHANGELOG.md | 3 + README.md | 10 + lib/generators/react_on_rails/USAGE | 65 +++ .../react_on_rails/doctor_generator.rb | 256 +++++++++++ .../react_on_rails/system_checker.rb | 399 ++++++++++++++++++ .../react_on_rails/doctor_generator_spec.rb | 121 ++++++ .../react_on_rails/system_checker_spec.rb | 276 ++++++++++++ 7 files changed, 1130 insertions(+) create mode 100644 lib/generators/react_on_rails/USAGE create mode 100644 lib/generators/react_on_rails/doctor_generator.rb create mode 100644 lib/generators/react_on_rails/system_checker.rb create mode 100644 spec/lib/generators/react_on_rails/doctor_generator_spec.rb create mode 100644 spec/lib/generators/react_on_rails/system_checker_spec.rb diff --git a/CHANGELOG.md b/CHANGELOG.md index 27a2fed942..f703833560 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -58,6 +58,9 @@ Changes since the last non-beta release. - **Cleaner generated code**: Streamlined templates following modern React and TypeScript best practices - **Improved helper methods**: Added reusable `component_extension` helper for consistent file extension handling +#### Added +- **`react_on_rails:doctor` generator**: New diagnostic command to validate React on Rails setup and identify configuration issues.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Refactored complex methods to reduce cyclomatic complexity - Added proper RuboCop disable comments for intentional class length - Fixed line length issues with proper string concatenation - Improved method organization and readability - Added proper respond_to_missing? methods for Rainbow fallback - Fixed test spec helper paths - Extracted reusable methods for better maintainability All RuboCop offenses have been resolved while maintaining functionality. šŸ¤– Generated with [Claude
