From 2cfe3cb7b91d724ade72e7292116e4d49ecedc1d Mon Sep 17 00:00:00 2001 From: Justin Gordon Date: Sun, 9 Nov 2025 17:45:21 -1000 Subject: [PATCH 01/15] Improve server bundle path configuration documentation and validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds clear documentation and automated validation to prevent configuration mismatches between webpack and React on Rails configurations. **Documentation Improvements:** - Add prominent warnings in both webpack config and Rails initializer templates - Clarify that both server_bundle_output_path settings must match - Explain the security rationale (private directories prevent code exposure) - Update generator templates with cross-reference comments **Doctor Validation:** - Add automated check that compares webpack serverWebpackConfig.js output.path with React on Rails server_bundle_output_path configuration - Display success message when configs are in sync - Provide detailed warning with fix instructions when mismatch detected - Gracefully handles missing config files or parsing errors **Why This Matters:** Webpack (build-time) and React on Rails (runtime) need to agree on where server bundles are located. Misconfiguration causes SSR failures that can be hard to debug. This change makes the requirement explicit and adds automated validation via the doctor command. **Technical Notes:** - Validation runs as part of `rails react_on_rails:doctor` analysis - Parses webpack config to extract output.path value - Compares paths relative to Rails.root - No breaking changes - pure documentation and tooling improvement Related to closed PR #1808 šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../config/initializers/react_on_rails.rb.tt | 15 +++++ .../config/webpack/serverWebpackConfig.js.tt | 12 +++- lib/react_on_rails/doctor.rb | 67 ++++++++++++++++++- 3 files changed, 90 insertions(+), 4 deletions(-) diff --git a/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt b/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt index e063171d21..309078d145 100644 --- a/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt +++ b/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt @@ -12,6 +12,21 @@ ReactOnRails.configure do |config| # Set to "" if you're not using server rendering config.server_bundle_js_file = "server-bundle.js" + # āš ļø IMPORTANT: This must match output.path in config/webpack/serverWebpackConfig.js + # + # Both are currently set to 'ssr-generated' (relative to Rails.root) + # Keeping these in sync ensures React on Rails can find the server bundle at runtime. + # + # Configure where server bundles are output.

Nov 2025 18:46:15 -1000 Subject: [PATCH 02/15] Fix validation to support multiple webpack patterns and add comprehensive tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses critical issues identified in code review: **Issue 1: Regex Pattern Too Restrictive** - Original regex only matched hardcoded path.resolve() pattern - Real dummy app uses config.outputPath, which wasn't matched at all - Validation would silently skip without detecting actual configs **Fix:** - Support hardcoded path: require('path').resolve(__dirname, '../../path') - Detect config.outputPath usage (can't validate, inform user) - Detect variable usage (can't validate, inform user) - Clear messaging for each pattern type **Issue 2: Missing Path Normalization** - String equality comparison failed on equivalent paths - ./ssr-generated vs ssr-generated would be false mismatch - Trailing slashes caused false positives **Fix:** - normalize_path() method strips leading ./ and / - Removes trailing slashes - Handles whitespace - Graceful handling of nil/non-string values **Issue 3: No Test Coverage** - New validation methods had zero tests - High risk of regressions **Fix:** - Added 20+ comprehensive test cases covering: - File not found scenarios - Hardcoded paths (matching and mismatched) - config.outputPath detection - Variable detection - Error handling - Path normalization edge cases - All return nil vs success vs warning paths **Testing Results:** - All 20 new tests passing - 30/31 total specs passing (1 pre-existing failure unrelated) - Covers real-world patterns including dummy app config **Technical Details:** - extract_webpack_output_path() now pattern-aware - Better user messaging for unvalidatable configs - Maintains backward compatibility - No breaking changes šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- lib/react_on_rails/doctor.rb | 57 +++++--

Addresses feedback from detailed code review: **1. Critical: Fix Asymmetric RuboCop Directives** - Issue: Line 667 only disabled Metrics/CyclomaticComplexity - But line 702 enabled BOTH Metrics/AbcSize and Metrics/CyclomaticComplexity - This asymmetry could cause violations - Fix: Changed line 667 to disable both cops symmetrically - Result: RuboCop reports method doesn't actually need AbcSize disabled, auto-fixed **2. Simplify Regex Pattern for Clarity** - Issue: Pattern `['"]\.\.[\/\.\.]+` was hard to read - Fix: Changed to explicit `['"]\.\.\/\.\.\/` to clearly match ../../path - Makes intent obvious: we match exactly two parent directory traversals - RuboCop auto-removed redundant escapes inside %r{} **3. Improve Documentation Discoverability** - Issue: Users might not know about the validation feature - Fix: Added "Run 'rails react_on_rails:doctor' to verify these configs are in sync" - Placement: In generator template right next to server_bundle_output_path config - Helps users discover the validation tool when they need it most **Testing:** - āœ… All 20 validation tests still passing - āœ… RuboCop passes with zero offenses - āœ… Regex pattern matches test cases correctly - āœ… 30/31 total specs passing (1 pre-existing failure unrelated) **Other Suggestions Considered:** - Reordering validation (decided current flow is good - validates immediately after config display) - Magic string constant (not needed - single use in method, clear context) - Trailing newline check (git hooks already enforce this automatically) šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../base/base/config/initializers/react_on_rails.rb.tt | 2 ++ lib/react_on_rails/doctor.rb | 1 + 2 files changed, 3 insertions(+) diff --git a/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt b/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt index 309078d145..f088deffac 100644 --- a/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt +++ b/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt @@ -17,6 +17,8 @@ ReactOnRails.configure do |config| # Both are currently set to 'ssr-generated' (relative to Rails.root) # Keeping these in sync ensures React on Rails can find the server bundle at runtime. # + # Run 'rails react_on_rails:doctor' to verify these configs are in sync. + # # Configure where server bundles are output.

Removed Fragile Regex Validation (doctor.rb)** - Removed `validate_server_bundle_path_sync` method (regex matching) - Removed `extract_webpack_output_path` method (pattern detection) - Removed `normalize_path` method (no longer needed) - Replaced with `check_shakapacker_private_output_path` method **3. Recommendation-Based Doctor Checks (doctor.rb)** - Detects Shakapacker version and capabilities - Pre-9.0: Recommends upgrading for better DX - 9.0+ without config: Shows how to configure private_output_path - 9.0+ with config matching: Success message - 9.0+ with config mismatch: Warning with fix instructions - No Shakapacker: Informs about manual configuration **4. Updated Generator Templates** - **React on Rails initializer**: Documents Shakapacker 9.0+ approach first - **Webpack config**: Shows config.privateOutputPath pattern - Both templates emphasize single source of truth in shakapacker.yml - Clear migration path for older Shakapacker versions **5. Comprehensive Test Coverage (8 new tests)** - Shakapacker not defined scenario - Pre-9.0 Shakapacker (no private_output_path support) - 9.0+ with matching config - 9.0+ with mismatched config - 9.0+ without config - Error handling - All tests passing **Benefits:** - No fragile regex parsing of webpack configs - Single source of truth in shakapacker.yml - Automatic configuration for Shakapacker 9.0+ users - Backward compatible with older Shakapacker versions - Clear upgrade path and recommendations - Robust error handling **Breaking Changes:** None - Existing configurations continue to work - Auto-detection only applies to default values - Explicit user configuration always takes precedence Addresses: @justin's feedback on PR #1967 šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../config/initializers/react_on_rails.rb.tt | 18 +- .../config/webpack/serverWebpackConfig.js.tt | 18 +- lib/react_on_rails/configuration.rb | 30 +++ lib/react_on_rails/doctor.rb | 118 ++++------ spec/lib/react_on_rails/doctor_spec.rb | 215 ++++++------------ 5 files changed, 165 insertions(+), 234 deletions(-) diff --git a/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt b/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt index f088deffac..7829c17084 100644 --- a/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt +++ b/lib/generators/react_on_rails/templates/base/base/config/initializers/react_on_rails.rb.tt @@ -12,17 +12,19 @@ ReactOnRails.configure do |config| # Set to "" if you're not using server rendering config.server_bundle_js_file = "server-bundle.js" - # āš ļø IMPORTANT: This must match output.path in config/webpack/serverWebpackConfig.js + # āš ļø RECOMMENDED: Use Shakapacker 9.0+ private_output_path instead # - # Both are currently set to 'ssr-generated' (relative to Rails.root) - # Keeping these in sync ensures React on Rails can find the server bundle at runtime. + # If using Shakapacker 9.0+, add to config/shakapacker.yml: + # private_output_path: ssr-generated # - # Run 'rails react_on_rails:doctor' to verify these configs are in sync. + # React on Rails will auto-detect this value, eliminating the need to set it here. + # This keeps your webpack and Rails configs in sync automatically. # - # Configure where server bundles are output.

Configuration API Reference (docs/api-reference/configuration.md)** - Added prominent recommendation for Shakapacker 9.0+ approach - Documents shakapacker.yml private_output_path configuration - Explains auto-detection behavior - Preserves documentation for older versions **2. Webpack Configuration Guide (docs/core-concepts/webpack-configuration.md)** - New section: "Server Bundle Configuration (Shakapacker 9.0+)" - Complete example with shakapacker.yml and webpack config - Lists benefits of the new approach: - Single source of truth - Automatic synchronization - No configuration duplication - Better maintainability - Notes compatibility with older versions **Key Points:** - Shakapacker 9.0+ users get automatic configuration - Backward compatible with manual configuration - Generator templates already show both approaches - Doctor command guides users to upgrade **Related Changes:** - Generator templates already updated in previous commit - Auto-detection implemented in configuration.rb - Doctor provides version-aware recommendations šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- docs/api-reference/configuration.md | 228 ++++++++++++++++++++ docs/core-concepts/webpack-configuration.md | 32 +++ 2 files changed, 260 insertions(+) diff --git a/docs/api-reference/configuration.md b/docs/api-reference/configuration.md index 19e6fd9549..5dba40d692 100644 --- a/docs/api-reference/configuration.md +++ b/docs/api-reference/configuration.md @@ -94,6 +94,234 @@ ReactOnRails.configure do |config| # This controls what command is run to build assets during tests ################################################################################ config.build_test_command = "RAILS_ENV=test bin/shakapacker" + + # + # React Server Components and Streaming SSR are React on Rails Pro features. + # For detailed configuration of RSC and streaming features, see: + # https://github.com/shakacode/react_on_rails/blob/master/react_on_rails_pro/docs/configuration.md + # + # Key Pro configurations (configured in ReactOnRailsPro.configure block): + # - rsc_bundle_js_file: Path to RSC bundle + # - react_client_manifest_file: Client component manifest for RSC + # - react_server_client_manifest_file: Server manifest for RSC + # - enable_rsc_support: Enable React Server Components + # + # See Pro documentation for complete setup instructions. + + ################################################################################ + # SERVER BUNDLE SECURITY AND ORGANIZATION + ################################################################################ + + # āš ļø RECOMMENDED: Use Shakapacker 9.0+ for Automatic Configuration + # + # For Shakapacker 9.0+, add to config/shakapacker.yml: + # private_output_path: ssr-generated + # + # React on Rails will automatically detect and use this value, eliminating the need + # to configure server_bundle_output_path here.
