131-143: Consider moving dev-environment checks into SystemChecker.Reduces DoctorGenerator size and keeps all validations in one place.
242-252: Avoid hard process exit in generators.Returning a status (and letting Thor/Rake handle exit codes) makes this easier to test and compose. Keep exits if you must, but consider a flag to skip exit for testability.
Would you like a patch that returns a status symbol instead of calling exit?

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`
3. RSC support validation during component registration
This makes additional validation in the helper methods unnecessary.

Rainbow fallback is broken (calling a constant instead of the Rainbow() method).
When the gem is missing, Rainbow("...") will raise NoMethodError. Provide a Kernel-level Rainbow method instead.

In lib/generators/react_on_rails/doctor_generator.rb around lines 7 to 38, the
fallback defines a Rainbow constant class so calls like Rainbow("...") will
raise NoMethodError; instead define a top-level Kernel method named Rainbow that
accepts text and returns a SimpleColorWrapper (or an instance capable of
responding to color methods) and ensure respond_to_missing?/method_missing on
the wrapper remain intact so Rainbow("...").red etc. work; replace or add a
Kernel-level def Rainbow(text) that returns SimpleColorWrapper.new(text) and
keep the existing class definitions as the implementation used by that method.

In lib/generators/react_on_rails/system_checker.rb around lines 80-85 (and
similarly at lines 361-363), the current package manager detection relies on
`which` which fails on Windows; change the CLI existence check to detect the OS
and run `where <cmd>` on Windows and `command -v <cmd>` (or `which <cmd>`) on
POSIX, capturing the command's exit status and returning a boolean, suppressing
stdout/stderr; update the cli_exists? helper (and any duplicate logic at
361-363) to perform this platform branch so Windows systems are not reported as
false negatives.

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`
3. RSC support validation during component registration
This makes additional validation in the helper methods unnecessary.

spec/lib/generators/react_on_rails/system_checker_spec.rb (12)
46-51: Assert by type, not by order, to avoid brittle “last message” checks.
Order can change as validations grow; match by type+content instead.Apply this diff:
- expect(checker.messages.last[:content]).to include("Node.js is required") + expect(checker.messages.any? { |m| m[:type] == :error && m[:content].include?("Node.js is required") }).to be true
68-79: Loosen the stub for backticks and avoid “last” assertion.
Reduces coupling to exact shell string and message ordering.Apply this diff:
- allow(checker).to receive(:`).with("node --version 2>/dev/null").and_return("v16.14.0\n") + allow(checker).to receive(:`).with(a_string_including("node --version")).and_return("v16.14.0\n") @@ - expect(checker.warnings?).to be true - expect(checker.messages.last[:content]).to include("Node.js version v16.14.0 detected") + expect(checker.warnings?).to be true + expect(checker.messages.any? { |m| m[:type] == :warning && m[:content].include?("Node.js version v16.14.0 detected") }).to be true
81-92: Loosen the stub for backticks.
Prevents future breakage if implementation tweaks redirection.Apply this diff:
- allow(checker).to receive(:`).with("node --version 2>/dev/null").and_return("v18.17.0\n") + allow(checker).to receive(:`).with(a_string_including("node --version")).and_return("v18.17.0\n")
94-105: Loosen the stub for backticks.
Same rationale as above.Apply this diff:
- allow(checker).to receive(:`).with("node --version 2>/dev/null").and_return("") + allow(checker).to receive(:`).with(a_string_including("node --version")).and_return("")
113-119: Avoid relying on message order.
Assert by type+content.Apply this diff:
- expect(checker.errors?).to be true - expect(checker.messages.last[:content]).to include("No JavaScript package manager found") + expect(checker.errors?).to be true + expect(checker.messages.any? { |m| m[:type] == :error && m[:content].include?("No JavaScript package manager found") }).to be true
129-133: Assert content without coupling to exact ordering “npm, yarn”.
Future additions (pnpm/bun) or reorder won’t break the spec.Apply this diff:
- expect(checker.messages.any? { |msg| msg[:type] == :success && msg[:content].include?("npm, yarn") }).to be true + expect(checker.messages.any? { |msg| msg[:type] == :success && msg[:content].include?("npm") && msg[:content].include?("yarn") }).to be true
143-148: Avoid relying on message order.
Match by type+content.Apply this diff:
- expect(checker.errors?).to be true - expect(checker.messages.last[:content]).to include("Shakapacker is not properly configured") + expect(checker.errors?).to be true + expect(checker.messages.any? { |m| m[:type] == :error && m[:content].include?("Shakapacker is not properly configured") }).to be true
169-181: Stabilize the “gem loaded” example by stubbing require.
Without stubbing, this spec depends on the dev/test environment having the gem installed.Apply this diff:
before do # Mock the ReactOnRails constant and VERSION stub_const("ReactOnRails", Module.new) stub_const("ReactOnRails::VERSION", "16.0.0") + allow(checker).to receive(:require).with("react_on_rails").and_return(true) end

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`
3. RSC support validation during component registration
This makes additional validation in the helper methods unnecessary.

Remove redundant RuboCop disable for RSpec/FilePath
RuboCop reports Lint/RedundantCopDisableDirective: RSpec/FilePath is unnecessary — remove RSpec/FilePath from the disable so only RSpec/SpecFilePathFormat remains (or replace with RSpec/Dialect if that was the intended cop). Location: spec/lib/generators/react_on_rails/system_checker_spec.rb:6. Re-run RuboCop (or run autocorrect) and commit the fix.

The method uses backtick command execution but doesn't handle potential errors or edge cases. Consider using system with null redirection like other methods in this class for consistency and to avoid potential output capture issues.

The fallback implementation for Rainbow defines global classes that could conflict with actual Rainbow gem classes if it's loaded later. Consider namespacing these fallback classes or using a different approach like a module-level constant to avoid potential conflicts.

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`
3. RSC support validation during component registration
This makes additional validation in the helper methods unnecessary.

222-244: Good, concise recommendations sectionThe structure, coloring, and gating on errors/warnings read well.
171-176: Nice summary aggregationMessage counting and conditional verbosity are clean and easy to follow.
126-138: Helpful SSR bundle checkClear, actionable guidance when the server bundle is missing.
98-106: Order of checks looks sensibleEnvironment, packages, then Shakapacker config makes troubleshooting progressive.
193-204: User-friendly summary textGood UX with celebratory/sober tones based on outcome.
214-220: Message color mapping is cleanUsing MESSAGE_COLORS with a default is tidy.
64-74: Header output is clearNice branding and consistent formatting.
306-338: Request: confirm Windows compatibility for which/yarn checksSystemChecker uses ReactOnRails::Utils.running_on_windows? for node detection. Here we rely on which. Consider using a small helper to detect Yarn on Windows (where command is where.exe).
Would you like me to add a tiny helper method (cross‑platform cli_exists?) here to mirror SystemChecker?
1-1: Frozen string literal pragma: goodPrevents inadvertent string mutations.
353-364: Return code contract — confirm callers expect process exit (not a returned integer)lib/react_on_rails/doctor.rb currently calls exit(1)/exit(0) (lines 353–364); spec/lib/react_on_rails/doctor_rake_task_spec.rb references the rake task. Confirm that the rake task and any generators that invoke Doctor rely on the process exit code (Doctor calling exit), or change exit_with_status to return an integer and update callers to call exit(...) themselves.

lib/react_on_rails/doctor.rb around lines 397 to 399: the current yarn detection
uses a shell string ("which yarn > /dev/null 2>&1") which is shell-injection
prone and fails on Windows; replace it with an argv-style system call that
invokes yarn directly and redirects output using File::NULL (e.g. system('yarn',
'--version', out: File::NULL, err: File::NULL)) so the check runs without a
shell and works cross-platform; update has_yarn_test_script? to use that
argv-form system call while keeping the has_npm_test_script? condition.

Critical: Fix unsafe shell/backtick invocations (shell‑injection risk)
-
Repo search shows multiple string-based shell invocations and backticks that build/execute shell strings with interpolated values. Key locations to fix:
- lib/generators/react_on_rails/generator_helper.rb —
cd ... && ln -s ...backtick (use File.symlink/FileUtils.ln_s). - lib/react_on_rails/system_checker.rb — cli_exists? uses
system("which #{command} > /dev/null 2>&1")(use system("which", command) or avoid shelling out). - lib/generators/react_on_rails/install_generator.rb — missing_node? / node version checks use backticks/
which/where. - lib/generators/react_on_rails/generator_messages.rb — detect_process_manager uses string system("which ...").
- lib/react_on_rails/git_utils.rb — backtick
git status --porcelain(use Open3.capture3('git','status','--porcelain')). - lib/react_on_rails/dev/file_manager.rb — uses backticks for pgrep.
- (There are other generator files using string system calls; review all occurrences from the search.)
- lib/generators/react_on_rails/generator_helper.rb —
-
Required changes: replace string-shell invocations with safe alternatives — system with separate args (system(cmd, arg,...)), Open3.capture3 with arg lists, direct Ruby APIs (File.symlink/FileUtils), or sanitize/whitelist inputs with Shellwords.escape when unavoidable. Update tests that stub these calls.

🤖 Prompt for AI Agents
In lib/react_on_rails/system_checker.rb (lines 1–578), the methods node_missing?
and cli_exists? use backticks and shell-interpolated system calls which are
vulnerable to shell injection; replace those with safe, non-shell invocations.
For cli_exists?(command) call a platform-appropriate external checker via
argumentized APIs (e.g., Open3.capture3("which", command) /
Open3.capture3("where", command) on Windows) and check the returned status
instead of interpolating into a shell string; similarly change node_missing? to
call the proper program checker via Open3.capture3 or system with separate args
and inspect the Process::Status rather than using backticks and shell redirects.
Ensure you avoid building shell strings with untrusted input, use Ruby File/Dir
APIs where applicable, and update any tests that stub or mock these shell calls
to stub the new Open3/system call signatures.
🔍 Code Review for react_on_rails:doctor EnhancementThank you for this comprehensive enhancement to the doctor diagnostic tool! I have completed a thorough review of the changes and I am impressed with the significant improvements. Here is my detailed feedback: ✅ Strengths1. Excellent Architecture & Code Organization
2. Security Best Practices ✨
3. Comprehensive Diagnostics
4. User Experience Improvements
🎯 Suggestions for Improvement1. Performance OptimizationConsider caching frequently accessed files to avoid multiple reads. For example, package.json is read multiple times throughout the diagnostic process. A simple memoization pattern could improve performance. 2. Method ComplexitySome methods like check_v16_breaking_changes (lines 891-941) have high cyclomatic complexity. Consider extracting checks into separate methods for better maintainability and testability. 3. Error Handling EnhancementWhile error handling is generally good, consider using more specific exceptions in critical paths instead of catching generic StandardError. This would make debugging easier and prevent masking unexpected errors. 4. Test CoverageThe test coverage is good but could be enhanced:
🐛 Minor Issues
💡 Additional Recommendations
🎉 Overall AssessmentThis is a high-quality PR that significantly enhances the diagnostic capabilities of React on Rails. The security improvements alone (Open3 usage) make this valuable, and the comprehensive configuration analysis will help many developers troubleshoot issues more effectively. The code follows Ruby best practices, is well-documented, and includes appropriate test coverage. With the minor improvements suggested above, this will be an excellent addition to the React on Rails toolkit. Recommendation: Approve with minor suggestions ✅ The PR is ready to merge after addressing the minor issues mentioned. The performance optimizations and enhanced error handling can be addressed in follow-up PRs if needed. Great work on this comprehensive enhancement! 🚀 |

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`

🤖 Prompt for AI Agents
In lib/generators/react_on_rails/USAGE around lines 2-4 (and also update lines
12-21), the document incorrectly calls react_on_rails:doctor a "generator" and
shows generator usage examples; update the wording to state it is a Rake task
and replace all instances of "generator" with "Rake task" (or "rake task"),
change example commands to the rake invocation (e.g., rake react_on_rails:doctor
or bundle exec rake react_on_rails:doctor), and adjust any explanatory text to
reference running the rake task rather than generator usage.

5-12: Well-structured critical requirements section for development workflow.Adding a dedicated "CRITICAL REQUIREMENTS" section aligns with best practices used by diagnostic tools in the Ruby ecosystem, emphasizing essential pre-commit checks. The emphasis on RuboCop compliance and trailing newlines helps maintain code quality standards.
23-27: Clear emphasis on mandatory linting requirements.The restructuring emphasizes mandatory RuboCop compliance while maintaining access to all available linting tools. This aligns well with the project's quality standards and the new doctor diagnostic feature being introduced.
29-29: Update formatting command from yarn to rake.Good consolidation - using
rake autofixprovides a unified entry point for code formatting instead of directly calling yarn commands.
33-33: Strong reinforcement of pre-push requirements.The repeated emphasis on mandatory RuboCop compliance before pushing helps prevent CI failures and maintains code quality. This is particularly important for a project introducing comprehensive diagnostic tooling.
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] 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

- Applied Prettier formatting to fix CI formatting checks - Added newline after 'Added' section in CHANGELOG.md - Updated CLAUDE.md with correct autofix command 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
…nt checks - Convert Rails generator to proper namespaced rake task (rake react_on_rails:doctor) - Remove irrelevant git status and hello_world checks that don't belong in a diagnostic tool - Move SystemChecker from generators namespace to ReactOnRails module for better organization - Update all documentation and tests to reflect the new rake task approach - Maintain all core diagnostic functionality while improving usability This makes the doctor command behave like other Rails diagnostic tools (e.g., rake routes) rather than a code generation tool, which was inappropriate for its diagnostic purpose. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Doctor now reports installed versions of React, React DOM, Shakapacker, and Webpack - Versions are displayed as informational messages during diagnosis - Sets foundation for future version compatibility checks and upgrade recommendations - All versions extracted from package.json and Gemfile.lock respectively This provides valuable context for troubleshooting and future upgrade planning. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Doctor now reads shakapacker.yml to determine correct source paths
- Extracts server bundle filename from react_on_rails.rb initializer
- Constructs accurate bundle path: {source_path}/{source_entry_path}/{bundle_filename}
- Falls back to default paths when configuration files are missing
- Fixes false warnings when using custom Shakapacker configurations
This resolves issues where doctor reported missing server bundles that actually
existed at custom paths defined in shakapacker.yml.
Example: client/app/packs/server-bundle.js vs app/javascript/packs/server-bundle.js

1049-1050: Fix shell injection vulnerability in yarn detection.The system call uses a shell string that's vulnerable to command injection. This was flagged in a previous review.
Apply this diff to fix the vulnerability:
def yarn_test_script? - npm_test_script? && system("which yarn > /dev/null 2>&1") + return false unless npm_test_script? + + if ReactOnRails::Utils.running_on_windows? + system("where", "yarn", out: File::NULL, err: File::NULL) + else + system("which", "yarn", out: File::NULL, err: File::NULL) + end endLet me verify if there are other similar shell injection issues:
#!/bin/bash # Check for other potential shell injection vulnerabilities in the codebase echo "Checking for system calls with string interpolation..." rg -n 'system\s*\(\s*["'\''][^"'\'']*#\{' --type ruby echo -e "\nChecking for backtick usage..." rg -n '`[^`]+#\{[^}]+\}[^`]*`' --type ruby echo -e "\nChecking for system calls with shell redirections..." rg -n 'system\s*\([^)]*>\s*/dev/null' --type ruby
🧹 Nitpick comments (7)
spec/lib/react_on_rails/system_checker_spec.rb (4)
3-4: Consider using Rails-standard spec_helper require pattern.The current require pattern uses a custom relative path. Consider following Rails conventions for better maintainability.
-require_relative "../../react_on_rails/spec_helper" -require_relative "../../../lib/react_on_rails/system_checker" +require "spec_helper" +require "react_on_rails/system_checker"Alternatively, if the relative path is intentional for the gem structure, ensure the spec_helper path is correct.
67-78: Consider testing exact warning message content.The test only checks if the version is included in the message but doesn't validate the full warning message format, which could lead to inconsistent user-facing messages.
it "adds a warning message" do checker.check_node_version expect(checker.warnings?).to be true - expect(checker.messages.last[:content]).to include("Node.js version v16.14.0 detected") + warning_message = checker.messages.last[:content] + expect(warning_message).to include("Node.js version v16.14.0 detected") + expect(warning_message).to include("React on Rails recommends Node.js 18+") + expect(warning_message).to include("Consider upgrading") end
210-227: Test coverage gap: Pre-release version handling.The version pattern tests don't cover pre-release versions (e.g., "16.0.0-beta.1"). Consider adding test cases for these scenarios.
Would you like me to add test cases for pre-release version patterns? This would ensure the doctor handles beta/alpha/RC versions correctly.
it "handles pre-release version patterns" do checker.send(:check_version_patterns, "16.0.0-beta.1", "16.0.0") expect(checker.warnings?).to be false end it "warns about pre-release with pattern modifiers" do checker.send(:check_version_patterns, "^16.0.0-beta.1", "16.0.0") expect(checker.warnings?).to be true expect(checker.messages.last[:content]).to include("caret (^) version pattern") end
403-407: Missing assertion on the specific info message type.The test checks for an info message containing "Shakapacker version: 7.1.0" but doesn't verify it's specifically an info type message.
it "reports shakapacker version" do checker.send(:report_shakapacker_version) expect(checker.messages.any? do |msg| - msg[:type] == :info && msg[:content].include?("Shakapacker version: 7.1.0") + msg[:type] == :info && msg[:content] == "📦 Shakapacker version: 7.1.0" end).to be true endlib/tasks/doctor.rake (1)
44-50: Consider adding input validation for environment variables.While the boolean conversion is straightforward, consider defensive programming for unexpected values.
task :doctor do - verbose = ENV["VERBOSE"] == "true" - fix = ENV["FIX"] == "true" + verbose = %w[true 1 yes].include?(ENV["VERBOSE"]&.downcase) + fix = %w[true 1 yes].include?(ENV["FIX"]&.downcase) doctor = ReactOnRails::Doctor.new(verbose: verbose, fix: fix) doctor.run_diagnosis endlib/react_on_rails/doctor.rb (1)
890-942: Consider extracting version check logic to reduce complexity.This method has high cyclomatic complexity. Consider extracting the file scanning logic and version checking into separate methods.

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`

23-33: LGTM! Critical linting requirements are well emphasized.The mandatory linting steps are clearly documented with appropriate warnings about CI failures. The formatting commands are comprehensive, covering both ESLint and RuboCop.
lib/tasks/doctor.rake (1)
7-38: LGTM! Rainbow fallback implementation is now correct.The fallback Rainbow implementation properly defines a Kernel-level method and handles method chaining correctly. This addresses the previous review comment about the broken fallback.
lib/react_on_rails/system_checker.rb (4)
374-377: LGTM! Cross-platform Node detection is properly implemented.The implementation correctly uses Open3.capture3 with argv form and handles Windows compatibility. This addresses the previous security concern about shell injection.
379-383: LGTM! Command existence check is secure and cross-platform.The cli_exists? method properly avoids shell injection by using argv form with Open3.capture3 and handles Windows compatibility.
608-640: LGTM! Proper semantic version comparison implemented.The method correctly uses Gem::Version for semantic version comparison instead of float math, which properly handles versions like 8.10.0. This addresses the previous concern about incorrect version threshold checks.
541-571: LGTM! Gemfile version pattern detection is correctly implemented.The method properly checks for tilde (~) version patterns and >= ranges with correct regex patterns. The use of match? is appropriate for performance.

In CLAUDE.md around line 102 the file has an inconsistent trailing newline that
breaks the pipeline; open the file and ensure the file ends with exactly one
POSIX newline character (no extra blank lines), add a single trailing newline if
missing or remove extra blank lines so the file terminates with one newline,
then save and commit.
- Add blank line after heading for better formatting - Remove trailing newline to match Prettier style - Resolves CI formatting check failures 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
