WalkthroughAdds a markdown troubleshooting/help block to README and surfaces that content in runtime and tooling error paths: new Utils helper returns formatted troubleshooting text (with fallback), the rake task prints it on errors, and several error/server-rendering paths append or raise errors including the troubleshooting section.

lib/tasks/generate_packs.rake (1)
145-166: Also show help for framework errors.Consider calling show_help_and_support from handle_react_on_rails_error so users get the same support options for known ReactOnRails::Error cases.
Apply:
def handle_react_on_rails_error(error) ... show_documentation_links + show_help_and_support endlib/react_on_rails/utils.rb (3)
61-62: Colorize help here for consistency.invoke_and_exit_if_failed prints the help block without colors; generate_packs.rake prints a colored version. Optional: reuse the same coloring so UX is consistent across call sites (or add a small Utils helper to print colored help to avoid duplication).
284-307: Robust extraction with good fallbacks.Overall extraction logic and defaults look solid. Optional: lift the start/end markers to frozen constants to avoid string duplication and enable simple unit tests.
I can add a spec that stubs README contents to exercise: missing markers, malformed order, happy path, and error handling. Want me to draft it?
328-330: Consolidate duplicate gem_root helpers.
rakelib/task_helpers.rb:6–8 and lib/react_on_rails/utils.rb:328–330 both define gem_root (File.expand_path("..", dir) vs File.expand_path("../..", dir)); extract a single canonical implementation and reference it everywhere to avoid duplication/drift.

Terminal output loses actual URLs (link text only).
Because Utils.convert_markdown_to_terminal strips links to plain text, this colored printer will show “Join our community” without the invite URL. Fix the conversion in Utils to preserve “text: URL”. See my comment in utils.rb Lines 309-316.

Code Review for PR #1803: Add centralized help and support messaging systemThank you for this PR! I've completed a thorough review of the changes. Here's my feedback: ✅ Strengths
🔍 Suggestions for Improvement1. Missing Test Coverage (High Priority)The new extract_troubleshooting_section method lacks unit tests. Consider adding tests to spec/react_on_rails/utils_spec.rb to cover:
2. Performance Consideration (Medium Priority)The extract_troubleshooting_section method reads the README.md file on every error. Consider caching the result using memoization to avoid repeated file I/O operations. 3. Security: Path Traversal Protection (Low Risk)While gem_root is controlled internally, it's good practice to validate the constructed path to ensure it stays within expected boundaries. 4. Error Message ClarityIn lib/react_on_rails/server_rendering_pool/ruby_embedded_java_script.rb:153, you're both logging and raising. Consider if both are necessary, as it might lead to duplicate error output. 5. Consistent Error HandlingSome error classes append the troubleshooting section in their initializer (JsonParseError), while others do it in message construction (PrerenderError). Consider standardizing the approach. 📝 Minor Issues

ReactOnRails::Error without preserving the original exception context; modify
the raise to preserve the original exception and backtrace (e.g. use Ruby's
exception chaining via "raise ... from e" or instantiate the new error with
cause: e, or set the new error's backtrace to e.backtrace) so the original
backtrace/cause is retained while still logging the dynamic troubleshooting

In lib/react_on_rails/server_rendering_pool/ruby_embedded_java_script.rb around
lines 232-234, the current code builds an error message that unconditionally
appends Utils.default_troubleshooting_section and then raises a new
ReactOnRails::Error, which loses the original exception backtrace and can
duplicate the static help text; change it to construct the message without
repeating the troubleshooting section (only append the help if it’s not already
present), and raise the ReactOnRails::Error while preserving the original
exception backtrace by passing e.backtrace as the third argument (e.g., raise
ReactOnRails::Error, msg, e.backtrace).

Learning: In React on Rails, the force_load feature includes both explicit `data-force-load="true"` usage and the ability to hydrate components during the page loading state (`document.readyState === 'loading'`). Both capabilities require a Pro license, so the condition `!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading')` correctly gates both scenarios.

- README.md "Get Help & Support" (lines ~143–151) has no HTML start/end comment markers; the extractor needs them to reliably pull this block.
- lib/tasks/generate_packs.rake calls ReactOnRails::Utils.extract_troubleshooting_section, but lib/react_on_rails/utils.rb only defines default_troubleshooting_section and no extract_troubleshooting_section — the exact marker strings are not discoverable in the repo.

Code Review for PR #1803: Add centralized help and support messaging systemSummaryThis PR aims to centralize help and support messaging throughout the React on Rails gem, providing consistent error messaging with helpful troubleshooting information. While the intent is excellent for improving user experience, there are critical issues that need to be addressed. Critical Issues1. Missing Method ImplementationThe code calls ReactOnRails::Utils.extract_troubleshooting_section in lib/tasks/generate_packs.rake:128, but this method is not defined in the diff. This will cause a NoMethodError at runtime when the rake task encounters an error. File: lib/tasks/generate_packs.rake:128 Recommendation: Either add the missing extract_troubleshooting_section method implementation to lib/react_on_rails/utils.rb or use the existing default_troubleshooting_section method instead. 2. Inconsistent Error Messaging ApproachThe PR uses two different approaches:
This inconsistency could lead to confusion and maintenance issues. Potential Issues1. Documentation Drift RiskThe PR description mentions HTML comment markers for the help section in README.md, but these markers are not visible in the diff. If the dynamic extraction relies on these markers, removing or modifying them accidentally could break the help system silently. 2. Exception Handling ChainIn lib/react_on_rails/server_rendering_pool/ruby_embedded_java_script.rb:153-158, the error is being re-raised as a new ReactOnRails::Error instead of preserving the original exception type. This could affect error tracking and debugging. Good Practices

Comprehensive Pull Request Review: PR #1803OverviewThis PR introduces a centralized help and support messaging system to improve developer experience when encountering errors. While the concept is excellent, there are critical implementation issues that need to be addressed. ✅ Strengths
🔴 Critical Issues That Must Be Addressed1. Method Name MismatchThe rake task calls ReactOnRails::Utils.extract_troubleshooting_section but the implementation adds default_troubleshooting_section. This will cause a NoMethodError at runtime. 2. Missing Test CoverageNo tests are included for:
3. Potential Missing CodeThe default_troubleshooting_section method should be in lib/react_on_rails/utils.rb according to the diff, but needs verification that all changes are present. 📝 Suggested ImprovementsCode Quality
TestingAdd comprehensive test coverage for the new utility method and its integration points. Tests should verify that help messages appear correctly in all error scenarios. Performance✅ Minimal impact - changes only affect error paths, using efficient string concatenation Security✅ No security concerns - only hardcoded help text, no user input processing 🔧 Action Items
Recommendation: REQUIRES CHANGESOnce these issues are addressed, this will be a valuable addition that significantly improves the developer experience. The approach is sound, but the implementation needs these critical fixes before merging. Great initiative on improving the error messaging experience! 🎉 |
1. Fix undefined method error: Changed Utils.extract_troubleshooting_section to Utils.default_troubleshooting_section in rake task 2. Preserve original exception: Changed to re-raise original exception instead of wrapping in ReactOnRails::Error to maintain stack trace These fixes address the blocker issues identified in the code review. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Code Review for PR #1803: Add centralized help and support messaging systemSummaryThis PR successfully centralizes help and support messaging across the React on Rails gem's error handling. The implementation is clean and follows good software engineering practices. The decision to use hardcoded messages instead of dynamic extraction from README.md is pragmatic and appropriate. Strengths
Issues Found1. Undefined Method Reference (BUG)In lib/tasks/generate_packs.rake line 127, the method calls ReactOnRails::Utils.extract_troubleshooting_section which does not exist. This should be ReactOnRails::Utils.default_troubleshooting_section This is a critical bug that will cause the rake task to fail when encountering errors. 2. Missing Test CoverageNo tests have been added for the new default_troubleshooting_section method. Consider adding:
3. Potential Performance ConsiderationWhile minor, the heredoc in JsonParseError#initialize creates a new string on every error. Consider memoizing or using string concatenation if this error is raised frequently. Suggestions for Improvement
Security ConsiderationsNo security issues identified. The hardcoded approach actually improves security by avoiding file I/O operations during error handling. Performance ImpactMinimal performance impact - adding a few string concatenations to error paths that are already slow by nature. Compliance with CLAUDE.md
VerdictNeeds revision - The undefined method bug in generate_packs.rake must be fixed before merging. Once that's addressed and ideally some basic tests are added, this will be a valuable improvement to the developer experience. Great work on improving the error messaging system! The centralized approach will make future maintenance much easier. |

2. Potential Performance Concern 🟡The help section is appended to every error message, even in production. Consider:
3. Hard-coded URLs 🟡The Slack invite URL (https://invite.reactrails.com) is hardcoded. If this URL changes, it requires a gem update. Consider:
4. Inconsistent Error Formatting 🟡Some errors use string concatenation while others use heredocs. For consistency, consider using heredocs for all multi-line error messages. 5.
