Justin Gordon Date: Sun, 2 Nov 2025 11:20:35 -1000 Subject: [PATCH 04/30] Fix CSS Modules compatibility with Shakapacker 9.0.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Shakapacker 9.0.0 introduced a breaking change where CSS Modules now use named exports by default (namedExport: true). This breaks existing code using default imports like `import styles from './styles.module.css'`. This commit restores backward compatibility by configuring css-loader to: - Set namedExport: false to allow default imports - Use exportLocalsConvention: 'camelCase' for consistent naming This allows existing code to continue working without changing all import statements to use named exports.

Package installed with semver range instead of exact version - package_json gem was adding packages with carets (^16.1.1) - React on Rails requires exact version matching between gem and npm package - Solution: Use npm install --save-exact directly for react-on-rails package Changes: - lib/react_on_rails/engine.rb: Skip validation during generator runs - lib/generators/react_on_rails/install_generator.rb: Use --save-exact flag Note: Filed issue with package_json gem to add exact version support: https://github.com/G-Rath/package_json/issues/25 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../react_on_rails/install_generator.rb | 17 ++++++----------- lib/react_on_rails/engine.rb | 3 +++ 2 files changed, 9 insertions(+), 11 deletions(-) diff --git a/lib/generators/react_on_rails/install_generator.rb b/lib/generators/react_on_rails/install_generator.rb index f39168bc37..aee51a9449 100644 --- a/lib/generators/react_on_rails/install_generator.rb +++ b/lib/generators/react_on_rails/install_generator.rb @@ -461,25 +461,20 @@ def add_js_dependencies def add_react_on_rails_package major_minor_patch_only = /\A\d+\.\d+\.\d+\z/ - # Try to use package_json gem first, fall back to direct npm commands + # Always use direct npm install with --save-exact to ensure exact version matching + # The package_json gem doesn't support --save-exact flag react_on_rails_pkg = if ReactOnRails::VERSION.match?(major_minor_patch_only) - ["react-on-rails@#{ReactOnRails::VERSION}"] + "react-on-rails@#{ReactOnRails::VERSION}" else puts "Adding the latest react-on-rails NPM module.

Fix package manager hard-coding (High Priority) - Add detect_package_manager_and_exact_flag helper to GeneratorHelper - Detect package manager from lock files (yarn, pnpm, bun, npm) - Update all package installation methods to use detected PM - Warn users when multiple lock files are detected - Fixes issue where npm was hard-coded, causing conflicts for yarn/pnpm/bun users 2. Fix fragile ARGV-based generator detection (Medium Priority) - Replace ARGV.any? check with explicit ENV variable - Install generator sets REACT_ON_RAILS_SKIP_VALIDATION=true - More robust than string matching on ARGV - Works correctly in all contexts (rake, console, tests) - Prevents false positives from paths containing "generate" or "g" 3. Add defensive checks to webpack CSS Modules config (Low Priority) - Add comprehensive type and existence checks before accessing loader properties - Prevents potential runtime errors with malformed webpack configs - Consistent with defensive pattern used for SCSS configuration All changes verified with: - bundle exec rubocop: 0 offenses - Install generator specs: 53 examples, 0 failures Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .github/workflows/lint-js-and-ruby.yml | 2 +- SHAKAPACKER_UPGRADE_PR_PLAN.md | 338 ++++++++++++++++++ .../react_on_rails/generator_helper.rb | 31 ++ .../react_on_rails/install_generator.rb | 17 +- lib/react_on_rails/engine.rb | 4 +- .../config/webpack/commonWebpackConfig.js | 14 - 6 files changed, 383 insertions(+), 23 deletions(-) create mode 100644 SHAKAPACKER_UPGRADE_PR_PLAN.md diff --git a/.github/workflows/lint-js-and-ruby.yml b/.github/workflows/lint-js-and-ruby.yml index 7616b20ea9..1583a3d561 100644 --- a/.github/workflows/lint-js-and-ruby.yml +++ b/.github/workflows/lint-js-and-ruby.yml @@ -107,7 +107,7 @@ jobs: run: cd spec/dummy && RAILS_ENV="test" bundle exec rake react_on_rails:generate_packs - name: Detect dead code run: | - yarn run knip + yarn run knip --no-config-hints yarn run knip --production - name: Lint JS run: yarn run eslint --report-unused-disable-directives diff --git a/SHAKAPACKER_UPGRADE_PR_PLAN.md b/SHAKAPACKER_UPGRADE_PR_PLAN.md new file mode 100644 index 0000000000..7d1b1d6678 --- /dev/null +++ b/SHAKAPACKER_UPGRADE_PR_PLAN.md @@ -0,0 +1,338 @@ +# Shakapacker 9.3.0 Upgrade - PR Breakdown Strategy + +## Current Status + +- **Master branch**: Shakapacker 8.2.0 (per Gemfile.lock) +- **Feature branch**: Shakapacker 9.3.0 +- **Total changes**: 90 commits, 402 files modified + +## Key Architectural Notes + +- **Babel**: Used for non-React Server Components +- **SWC**: Used for React Server Components +- **React version**: React 19 with conditional exports ('react-server' vs 'default') + +--- + +## Recommended PR Sequence + +### PR #1: Preparatory Refactoring (Low Risk) + +**Goal**: Extract changes that improve code quality without changing behavior + +**Commits to cherry-pick**: + +- `517f1579` - Fix unsafe system calls to use array form in pack_generator.rb +- `5186da7a` - Fix bin/dev pack generation in Bundler context +- `1c37907f` - Skip generate_packs when shakapacker precompile hook configured +- `e33826f8` - Fix generator robustness issues + +**Files changed**: + +- `lib/react_on_rails/dev/pack_generator.rb` +- `lib/react_on_rails/engine.rb` +- `lib/generators/react_on_rails/base_generator.rb` + +**Why first**: These are bug fixes and safety improvements that work with 8.2.0 + +**Risk**: Low - No dependency changes + +--- + +### PR #2: Version Validation Improvements (Low Risk) + +**Goal**: Improve version checking to handle Shakapacker upgrade scenarios + +**Commits to cherry-pick**: + +- `45821a25` - Add lockfile version resolution for exact version checking +- `777bee2e` - Skip version validation when package.json doesn't exist during setup +- `2def04b0` - Fix CI failure by skipping version validation during generator runtime +- `ae5425bd` - Fix generator validation by using environment variable +- `8b7fb6a1` - Skip version validation when react-on-rails package not installed +- `0d87ea75` - Unify release scripts and add strict version validation + +**Files changed**: + +- `lib/react_on_rails/version_checker.rb` +- `lib/react_on_rails/packer_utils.rb` +- `lib/generators/react_on_rails/base_generator.rb` +- Test files for version checking + +**Why second**: Sets up better version checking before we start upgrading + +**Risk**: Low - Only affects validation, not runtime behavior + +--- + +### PR #3: Babel Configuration Updates (Medium Risk) + +**Goal**: Update Babel config detection for Shakapacker 9.x path changes + +**Commits to cherry-pick**: + +- `6b76f956` - Fix using_swc? to properly parse YAML and default to babel +- `f454ea0d` - Update using_swc? to return true by default for Shakapacker 9.3.0 + +**Files changed**: + +- `lib/react_on_rails/packer_utils.rb` +- Test specs + +**Why third**: Shakapacker 9.x changed babel preset paths from `shakapacker/package/babel/preset.js` to different locations + +**Risk**: Medium - Changes transpilation detection logic + +**Testing needed**: + +- Verify non-RSC components still use Babel +- Verify RSC components can use SWC + +--- + +### PR #4: CSS Modules Compatibility Fix (Medium Risk) + +**Goal**: Fix CSS Modules namedExport issue with Shakapacker 9.x + +**Commits to cherry-pick**: + +- `364b730b` - Fix CSS Modules compatibility with Shakapacker 9.0.0 + +**Files changed**: + +- `spec/dummy/config/webpack/commonWebpackConfig.js` +- `react_on_rails_pro/spec/dummy/config/webpack/commonWebpackConfig.js` + +**Background**: +Shakapacker 9.0+ defaults CSS Modules to `namedExport: true`, breaking existing code that uses `import styles from './file.module.css'`.

This resolves the issue where preinstall scripts triggered yalc operations that modified yarn.lock, causing CI to fail with "--frozen-lockfile" checks. Changes: 1. Add explicit "Build and publish packages with yalc" step that runs yarn run yalc:publish for both root and Pro packages before install 2. Add --ignore-scripts flag to Pro dummy app yarn install to skip preinstall hook (since yalc already published in previous step) 3. Apply to all 3 jobs: build, rspec, and playwright tests This approach: - Separates build/publish from install for better CI reproducibility - Prevents yarn.lock modifications during install - Maintains frozen-lockfile enforcement for dependency stability - Faster CI (no redundant builds during preinstall) The preinstall script remains useful for local development to auto-update yalc packages, but in CI we use explicit steps for better control. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .github/workflows/pro-integration-tests.yml | 27 ++++++++++++++++++--- 1 file changed, 24 insertions(+), 3 deletions(-) diff --git a/.github/workflows/pro-integration-tests.yml b/.github/workflows/pro-integration-tests.yml index 8a11cd5d23..234861d391 100644 --- a/.github/workflows/pro-integration-tests.yml +++ b/.github/workflows/pro-integration-tests.yml @@ -92,8 +92,15 @@ jobs: sudo yarn global add yalc yarn install --frozen-lockfile --no-progress --no-emoji + - name: Build and publish packages with yalc + run: | + cd .. + yarn run yalc:publish + cd react_on_rails_pro + yarn run yalc:publish + - name: Install Node modules with Yarn for Pro dummy app - run: cd spec/dummy && yarn install --frozen-lockfile --no-progress --no-emoji + run: cd spec/dummy && yarn install --frozen-lockfile --ignore-scripts --no-progress --no-emoji - name: Install Ruby Gems for Pro dummy app run: | @@ -211,8 +218,15 @@ jobs: sudo yarn global add yalc yarn install --frozen-lockfile --no-progress --no-emoji + - name: Build and publish packages with yalc + run: | + cd .. + yarn run yalc:publish + cd react_on_rails_pro + yarn run yalc:publish + - name: Install Node modules with Yarn for Pro dummy app - run: cd spec/dummy && yarn install --frozen-lockfile --no-progress --no-emoji + run: cd spec/dummy && yarn install --frozen-lockfile --ignore-scripts --no-progress --no-emoji - name: Ensure minimum required Chrome version run: | @@ -402,8 +416,15 @@ jobs: sudo yarn global add yalc yarn install --frozen-lockfile --no-progress --no-emoji + - name: Build and publish packages with yalc + run: | + cd .. + yarn run yalc:publish + cd react_on_rails_pro + yarn run yalc:publish + - name: Install Node modules with Yarn for Pro dummy app - run: cd spec/dummy && yarn install --frozen-lockfile --no-progress --no-emoji + run: cd spec/dummy && yarn install --frozen-lockfile --ignore-scripts --no-progress --no-emoji - name: Ensure minimum required Chrome version run: | From 1920f0a8e2510d520a4e0a7e9d5a790dc7a397bd Mon Sep 17 00:00:00 2001 From: Justin Gordon Date: Sun, 2 Nov 2025 21:27:07 -1000 Subject: [PATCH 19/30] Add issue documentation for Playwright test to catch Turbo navigation regression MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Documents a regression that existed for over 1 year where JavaScript failed to work after Turbo navigation (only worked on hard refresh).

-1000 Subject: [PATCH 28/30] Update using_swc? to return true by default for Shakapacker 9.3.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Shakapacker 9.3.0 defaults to SWC compiler if javascript_compiler is not explicitly set in shakapacker.yml. Update the using_swc? method to reflect this new default behavior. Changes: - using_swc? now returns true (SWC) by default when config doesn't exist - using_swc? returns true unless javascript_compiler is explicitly set to babel - Updated template shakapacker.yml to comment out javascript_compiler setting - Added clear documentation that Shakapacker 9.3.0+ defaults to SWC This ensures the generator correctly detects and installs SWC dependencies by default, matching Shakapacker 9.3.0's new default compiler.

Changes: - Add require "yaml" to base_generator.rb - Parse YAML to read javascript_compiler from default section - Return true only when javascript_compiler is explicitly set to "swc" - Default to false (babel) when file is missing or key is absent - Add error handling for YAML parsing failures - Update template comment to reflect babel as default This ensures commented configuration lines don't affect compiler detection and provides more predictable behavior. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../react_on_rails/base_generator.rb | 21 +++++++++++++------ .../base/base/config/shakapacker.yml | 6 +++--- 2 files changed, 18 insertions(+), 9 deletions(-) diff --git a/lib/generators/react_on_rails/base_generator.rb b/lib/generators/react_on_rails/base_generator.rb index 2671c8cf19..1756b8063f 100644 --- a/lib/generators/react_on_rails/base_generator.rb +++ b/lib/generators/react_on_rails/base_generator.rb @@ -2,6 +2,7 @@ require "rails/generators" require "fileutils" +require "yaml" require_relative "generator_messages" require_relative "generator_helper" module ReactOnRails @@ -232,13 +233,21 @@ def add_dev_dependencies def using_swc? # Check shakapacker.yml for javascript_compiler setting - # Shakapacker 9.3.0 defaults to SWC if not specified + # Parse YAML to properly handle comments and get actual configured value shakapacker_config_path = File.join(destination_root, "config", "shakapacker.yml") - return true unless File.exist?(shakapacker_config_path) - - config_content = File.read(shakapacker_config_path) - # Return true (SWC) unless explicitly set to babel - !config_content.include?("javascript_compiler: babel") + return false unless File.exist?(shakapacker_config_path) + + begin + config = YAML.safe_load_file(shakapacker_config_path) + # Check default section for javascript_compiler setting + javascript_compiler = config.dig("default", "javascript_compiler") + # Return true only if explicitly set to "swc" + javascript_compiler == "swc" + rescue StandardError => e + # If YAML parsing fails, default to babel (false) + puts "Warning: Could not parse shakapacker.yml: #{e.message}" + false + end end def install_js_dependencies diff --git a/lib/generators/react_on_rails/templates/base/base/config/shakapacker.yml b/lib/generators/react_on_rails/templates/base/base/config/shakapacker.yml index 787538d52d..5a27cf5c37 100644 --- a/lib/generators/react_on_rails/templates/base/base/config/shakapacker.yml +++ b/lib/generators/react_on_rails/templates/base/base/config/shakapacker.yml @@ -58,9 +58,9 @@ default: &default # Compiler to use for JavaScript: 'babel' or 'swc' # SWC is faster but Babel has more plugins and wider ecosystem support - # Shakapacker 9.3.0+ defaults to 'swc' if not specified - # Uncomment to use Babel instead: - # javascript_compiler: babel + # React on Rails defaults to Babel if not specified for wider compatibility + # Uncomment and set to 'swc' for faster compilation: + # javascript_compiler: swc # Setting the asset host here will override Rails.application.config.asset_host. # Here, you can set different asset_host per environment.

Make precompile hook cross-platform: - Replace Unix-specific `command -v` with Ruby's system() array form - Use File::NULL for cross-platform output redirection - Use array form of system() calls for better reliability 3. Fix fragile config detection in precompile hook: - Use regex to match only actual config assignments - Ignore comments and strings containing config names 4. Remove development documentation files: - ISSUE_ANALYSIS.md - PR_REVIEW_RESPONSE.md - package_json_issue_comment.md 5.
