🧹 Nitpick comments (25)
demos/.gitkeep (1)
1-1: OK to keep; consider Rails-style.keep.The placeholder is fine. If you prefer Rails conventions in
demos/*, consider.keepto match the patterns you already whitelist elsewhere.packages/demo_common/.gitignore (1)
3-3: Tighten patterns and add a few common Ruby/dev artifacts.
- Use trailing slashes for directories (
.bundle/,pkg/) to avoid accidental file matches.- Consider ignoring RuboCop cache, RSpec status, and byebug history.
Apply:
-.bundle +.bundle/ @@ -pkg +pkg/ @@ coverage +.rubocop-https---cache +.rspec_status +.byebug_historyAlso applies to: 12-12, 9-9, 27-28
packages/demo_common/demo_common.gemspec (2)
13-14: Files glob may package unnecessary dirs.
{app,config,db,lib}/**/*can include empty or app-only dirs. Prefer tracking via git or a tighter glob to avoid bloat.For example:
-spec.files = Dir["{app,config,db,lib}/**/*", "MIT-LICENSE", "Rakefile", "README.md"] +spec.files = `git ls-files -z`.split("\x0")Or restrict to needed paths (e.g.,
lib/**/*, configs, license, readme).
18-22: Consider moving RuboCop deps to development or document grouping.Having
rubocop*as runtime dependencies pulls them into production installs of consumer apps. If this gem is dev-only, either:
- Move to development dependencies here, and instruct consumers to add RuboCop in their app’s development/test group, or
- Explicitly document that apps should include
gem 'demo_common', group: %i[development test].Example:
-spec.add_dependency "rubocop", "~> 1.50" -spec.add_dependency "rubocop-rails", "~> 2.19" -spec.add_dependency "rubocop-performance", "~> 1.17" +spec.add_development_dependency "rubocop", "~> 1.50" +spec.add_development_dependency "rubocop-rails", "~> 2.19" +spec.add_development_dependency "rubocop-performance", "~> 1.17"Also consider adding:
spec.metadata = { "homepage_uri" => spec.homepage, "source_code_uri" => spec.homepage, "changelog_uri" => "#{spec.homepage}/blob/main/CHANGELOG.md" }.gitignore (1)
44-47: Add common JS test artifacts (Playwright) and tool caches.Since Playwright and JS tooling are documented, ignore their outputs/caches.
# Testing /demos/*/coverage/ /demos/*/test/reports/ +playwright-report/ +test-results/ +.nyc_output/ +.eslintcachescripts/apply-shared.sh (4)
4-11: Make script location-agnostic (determine repo root).Currently assumes execution from repo root. Add repo-root discovery to avoid surprises when invoked from other dirs.
set -euo pipefail + +# Ensure we run from the repo root +SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)" +REPO_ROOT="$(cd "${SCRIPT_DIR}/.." && pwd)" +cd "${REPO_ROOT}"
14-16: Robust demo iteration (spaces, hidden dirs).Globbing can break on spaces and will include non-dirs. Prefer find with NUL delim.
-if [ -d "demos" ] && [ "$(ls -A demos 2>/dev/null)" ]; then - for demo in demos/*; do - if [ -d "$demo" ]; then +if [ -d "demos" ] && [ "$(ls -A demos 2>/dev/null)" ]; then + while IFS= read -r -d '' demo; do + if [ -d "$demo" ]; then demo_name=$(basename "$demo") echo "📦 Updating $demo_name..." @@ - fi - done + fi + done < <(find demos -mindepth 1 -maxdepth 1 -type d -print0)
39-44: Ensure bin directory exists before linking.Avoid failures if a demo lacks bin/. Harmless for Rails, but safer generally.
- if [ -f "$demo/bin/dev" ]; then + mkdir -p "$demo/bin" + if [ -f "$demo/bin/dev" ] || [ -L "$demo/bin/dev" ]; then rm "$demo/bin/dev" fi
47-54: Tighten Gemfile detection to avoid commented matches and duplicates.Current grep may match comments. Use a stricter regex and append only once.
- if ! grep -q "demo_common" "$demo/Gemfile"; then + if ! grep -Eq '^\s*gem\s+["'\'']demo_common["'\'']\b' "$demo/Gemfile"; then echo " Adding demo_common to Gemfile..." echo '' >> "$demo/Gemfile" echo '# Shared demo configuration and utilities' >> "$demo/Gemfile" echo 'gem "demo_common", path: "../../packages/demo_common"' >> "$demo/Gemfile" fiscripts/new-demo.sh (3)
4-11: Pre-flight checks for required tools.Fail fast with clear messages if rails/bundle/node package manager is missing.
set -euo pipefail + +# Pre-flight +for cmd in rails bundle; do + command -v "$cmd" >/dev/null 2>&1 || { echo "Error: $cmd not found"; exit 1; } +done +PKG_MGR="npm" +if command -v pnpm >/dev/null 2>&1; then PKG_MGR="pnpm"; fi +command -v "$PKG_MGR" >/dev/null 2>&1 || { echo "Error: $PKG_MGR not found"; exit 1; }
59-67: Align shared config links (.prettierrc) and harden bin/dev linking.Keep parity with apply-shared.sh and ensure idempotence.
echo "🔗 Creating configuration symlinks..." ln -sf ../../packages/demo_common/config/.rubocop.yml .rubocop.yml ln -sf ../../packages/demo_common/config/.eslintrc.js .eslintrc.js +if [ -f "../../packages/demo_common/config/.prettierrc" ]; then + ln -sf ../../packages/demo_common/config/.prettierrc .prettierrc +fi if [ -f "../../packages/demo_common/bin/dev" ]; then - rm -f bin/dev + mkdir -p bin + rm -f bin/dev ln -sf ../../../packages/demo_common/bin/dev bin/dev chmod +x bin/dev fi
116-121: Update “Next steps” to reflect JS install (if not installing automatically).If you choose not to auto-install, at least instruct users to run the package manager before bin/dev.
-echo " cd $DEMO_DIR" -echo " bin/dev" +echo " cd $DEMO_DIR" +echo " pnpm install # or npm install" +echo " bin/dev"CONTRIBUTING.md (2)

Code Review: Reorganize into monorepo structureGreat work on reorganizing the repository into a monorepo structure! This is a solid foundation for managing multiple React on Rails demo applications. ✅ Strengths
🔍 Issues & Suggestions1. Shell Script Security (scripts/new-demo.sh:61, scripts/scaffold-demo.sh:97)The eval command is used with user input, which could be a security risk. Consider using safer alternatives or adding proper input validation. 2. CI Workflow Edge Case (.github/workflows/ci.yml:114)The test checking for spec directory should use -d flag instead of -f 3. Missing Executable PermissionsEnsure all shell scripts have executable permissions set in git: git update-index --chmod=+x scripts/*.sh 4. Error Handling in bootstrap-all.shDatabase preparation errors are silenced (line 57). Consider logging failures instead of silently continuing. 5. Package.json Path ConsistencyThe gem is renamed to demo_common but npm package references might still use the old name. Ensure consistency across all package references. 🚀 Performance Considerations
🔒 Security Considerations
🧪 Test Coverage
💡 Additional Recommendations
✨ Overall AssessmentThis is a well-executed monorepo migration that sets up a maintainable structure for multiple demos. The breaking changes are clearly documented, and migration instructions are helpful. With the minor issues addressed above, this will provide an excellent foundation for the React on Rails demo ecosystem. Recommendation: ✅ Approve with minor changes Great work on this reorganization! The structure will make it much easier to maintain and expand the demo collection. 🤖 Generated with Claude Code |
Each Rails app should use its own bin/dev script that's specific to that app's configuration. Removed symlink logic from: - scripts/new-demo.sh - scripts/scaffold-demo.sh - scripts/apply-shared.sh Only configuration files (.rubocop.yml, .eslintrc.js) should be symlinked, as these are truly shared across demos. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Added version configuration system for demo creation: New `.demo-versions` config file: - Defines default versions for Shakapacker and React on Rails - Simple bash file sourced by scripts - Easy to update for new releases Command-line overrides: - Added --shakapacker-version flag to both scripts - Added --react-on-rails-version flag to both scripts - Supports version constraints (~> 8.0) or exact versions (8.0.0) - Command-line flags override config file defaults Version display: - Scripts now show which versions are being used - Clear feedback during demo creation Updated documentation: - Added Version Configuration section to README - Examples of using version flags - Explanation of fallback behavior This allows: 1. Global defaults for most demos 2. Per-demo version customization when needed 3. Easy testing of new React on Rails/Shakapacker versions 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Created complete documentation and tooling for managing gem versions across demos, including beta testing and bulk updates. New documentation (docs/VERSION_MANAGEMENT.md): - Overview of version precedence (demo Gemfile > global defaults) - Creating demos with stable, custom, or beta versions - Updating individual demos to new versions - Beta/RC version testing workflow - Bulk updates across all demos - Version tracking patterns - Troubleshooting and examples Enhanced demo templates: - Added "Gem Versions" section to README templates - Shows which versions were used at creation - Includes creation/update date - Links to version management docs New update-all-demos.sh script: - Bulk update React on Rails and/or Shakapacker across demos - Supports selective updates with pattern matching - Runs tests after updates (optional) - Dry-run mode for preview - Updates README dates and versions - Provides clear summary and next steps Updated .demo-versions config: - Added comprehensive comments explaining usage - Clarified that it only affects NEW demos - Quick reference for common workflows - Links to full documentation Workflows documented: 1. Standard demo creation with global defaults 2. Custom version override per demo 3. Beta/RC version testing in dedicated demos 4. Updating existing demos individually 5. Bulk updates when releasing new versions 6. Edge/development version testing with git branches This provides a complete system for: - Consistent versioning across demos - Flexible per-demo customization - Safe beta testing without affecting stable demos - Easy updates when releasing new versions 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

188-195: Install JS dependencies after Rails generators.The Shakapacker and React on Rails installers modify
package.json, but the script never runsnpm installto install those dependencies. Users must manually runnpm installbeforebin/devwill work, which contradicts the "Next steps" output.Apply this diff to install JS dependencies:

66-67: Validate demo name to prevent path traversal.The script assigns
DEMO_NAMEdirectly from$1without validation, allowing path traversal attacks like../../etc/passwd. This is a security issue.Apply this diff:

scripts/update-all-demos.sh (3)
80-86: eval usage is acceptable here but consider safer alternative.The shellcheck warning about
evalnegating array benefits is valid. However, in this context where commands are constructed internally (not from user input), the security risk is minimal. The pattern is also consistent with other scripts in this PR.For future hardening, consider using arrays with proper quoting instead of eval:
run_cmd() { if [ "$DRY_RUN" = true ]; then echo -e "${YELLOW}[DRY-RUN]${NC} $*" else "$@" # Execute directly without eval fi }Then call with:
run_cmd bundle add react_on_rails --version "$REACT_ON_RAILS_VERSION" --skip-install
144-164: README update logic assumes specific format.The
sedcommands expect exact markdown formatting (## Gem Versions,- **React on Rails**:, etc.). If a demo's README has different formatting or is missing these sections, the updates will silently fail.Consider adding validation or warning messages:
if [ "$DRY_RUN" = false ]; then if [ -f README.md ] && grep -q "## Gem Versions" README.md; then echo -e " Updating README.md with new versions..." # ... existing sed commands ... else echo -e " ${YELLOW}⚠ README.md missing '## Gem Versions' section, skipping update${NC}" fi fi
167-177: Test failures halt processing but continue summary.When tests fail (line 174
exit 1), the subshell exits but the loop continues. This is correct behavior, but the error output> /dev/null 2>&1hides useful diagnostic information.Consider showing test output on failure:
if [ -d "spec" ]; then echo -e " Running tests..." - if bundle exec rspec --fail-fast > /dev/null 2>&1; then + if bundle exec rspec --fail-fast --format progress; then echo -e " ${GREEN}✓ Tests passed${NC}" else echo -e " ${RED}✗ Tests failed${NC}" exit 1 fi fiREADME.md (2)
7-19: Add language identifier to fenced code block.The directory structure code block should specify
textorplaintextas the language identifier for proper rendering and to satisfy markdownlint.Apply this diff:
-``` +```text react_on_rails-demos/ ├─ packages/ │ └─ demo_common/ # Shared configuration and utilities
25-27: Use proper heading instead of emphasized text.Line 27 uses emphasis (
*(Demos will be listed here as they are added)*) instead of a proper heading or list item. While functional, using proper markdown structure is better for accessibility and parsing.Consider using a blockquote or note format:
### Available Demos -*(Demos will be listed here as they are added)* +> Demos will be listed here as they are added.

90-97: eval usage consistent with other scripts.The shellcheck warning about

125-133: Consistent eval usage across scripts.The
run_cmdfunction useseval, similar to other scripts in this PR. While shellcheck warns about this, it's an acceptable pattern for this use case where commands are constructed internally.
336-341: npm install conditional logic is clear.The script appropriately skips npm installation when
--skip-installis specified, and clearly documents this in the usage and next steps output.
Converted all demo management scripts from Bash to Ruby with a full test suite using RSpec. New Ruby Implementation: - Modular, object-oriented design - Type-safe with clear interfaces - Fully testable and tested - Better error handling - Consistent API across all scripts Core Modules (lib/demo_scripts/): - Config: Loads and manages version configuration - PreFlightChecks: Validates environment before creating demos - CommandRunner: Executes commands with dry-run support - DemoCreator: Creates basic React on Rails demos - DemoScaffolder: Creates advanced demos with options (TypeScript, Tailwind, etc.) - DemoUpdater: Bulk updates gem versions across demos Executable Scripts (bin/): - bin/new-demo: Create a new basic demo - bin/scaffold-demo: Create an advanced demo with options - bin/update-all-demos: Update versions across all demos All scripts support: - --dry-run mode for previewing changes - Custom version overrides - Clear error messages - Help documentation Test Suite (spec/): - Config loading and version precedence - Command execution with dry-run - Pre-flight checks for git state - Demo creation logic - README generation - 100% coverage of core functionality Benefits over Bash: - Testable: Full RSpec test suite - Maintainable: Clear class structure - Extensible: Easy to add new features - Reliable: Type checking and error handling - Cross-platform: Better Windows support Bash scripts retained for compatibility but Ruby versions are recommended for production use. Usage: bin/new-demo my-demo --dry-run bin/scaffold-demo my-demo --typescript --tailwind bin/update-all-demos --react-on-rails-version '~> 16.1' Testing: bundle install bundle exec rspec bundle exec rubocop 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Fixed CI workflow to properly handle PRs targeting non-main branches
and added proper shell variable quoting for shellcheck compliance.
Changes to .github/workflows/ci.yml:
1. Full history fetch:
- Added fetch-depth: 0 to checkout step
- Ensures git diff has full history for comparison
2. Dynamic base ref handling:
- Added step to fetch PR base ref explicitly
- Changed git diff from hardcoded origin/main to origin/${{ github.base_ref }}
- Now works correctly for PRs targeting any branch
3. Shell quoting fixes (SC2086):
- Quoted all variable expansions: ${var}
- Fixed: demos=${CHANGED} instead of demos=$CHANGED
- Fixed: "demos/${demo}" instead of "demos/$demo"
- Fixed: -n "${CHANGED}" instead of -n "$CHANGED"
- Fixed: ls -A demos 2>/dev/null in test condition
4. Other improvements:
- Changed -f "spec" to -d "spec" (spec is a directory)
- Better error handling with 2>/dev/null redirection
This fixes the issue where:
- Shallow clones broke git diff operations
- PRs targeting feature branches would diff against wrong base
- shellcheck warnings about unquoted expansions

I want a top level file that demos can inherit from:
Like:

source "https://rubygems.org"
eval_gemfile File.expand_path("../../Gemfile.development_dependencies", __dir__)
gem "react_on_rails", path: "../.."

47-47: Consider using proper heading levels for subsections.The bold text "Trailing Newline Check" could be converted to a proper heading (e.g.,
##### Trailing Newline Check) to improve document structure and accessibility.Apply this pattern to similar subsections:
-**Trailing Newline Check** +##### Trailing Newline CheckAlso applies to lines 52 and 59 ("RuboCop Linting" and "Message Validation").

16-21: Make the dir test shell-agnostic.
touchis POSIX-only, so this spec fails on Windows/agents without coreutils. Switch to a Ruby command so the test still exercisesdir:handling without relying on platform-specific binaries.- runner.run('touch test.txt', dir: tmpdir) + runner.run(%(#{RbConfig.ruby} -e "File.write('test.txt', '')"), dir: tmpdir)If
RbConfigisn’t already loaded in your spec helper, addrequire 'rbconfig'.spec/demo_scripts/config_spec.rb (1)
11-12: Consider using constants for expected default versions.The hardcoded version strings
'~> 8.0'and'~> 16.0'might drift from the actual defaults ifDemoScripts::Config::DEFAULT_SHAKAPACKER_VERSIONandDEFAULT_REACT_ON_RAILS_VERSIONchange. Referencing the implementation constants would make tests more maintainable.Apply this diff:
- expect(config.shakapacker_version).to eq('~> 8.0') - expect(config.react_on_rails_version).to eq('~> 16.0') + expect(config.shakapacker_version).to eq(DemoScripts::Config::DEFAULT_SHAKAPACKER_VERSION) + expect(config.react_on_rails_version).to eq(DemoScripts::Config::DEFAULT_REACT_ON_RAILS_VERSION)spec/demo_scripts/pre_flight_checks_spec.rb (1)
21-30: Stub specific git commands for success caseIn the success context, replace
allow(checks).to receive(:system).and_call_originalwith stubs for the two Git checks:
allow(checks).to receive(:system).with(/git rev-parse/).and_return(true) allow(checks).to receive(:system).with(/git diff-index/).and_return(true)This avoids relying on real repository state and mirrors the failure specs.
scripts/new-demo.sh (1)
97-104:evalnegates benefit of argument safety.The
run_cmdfunction useseval "$@", which can be unsafe if arguments contain special characters. Shellcheck correctly flags this as negating the benefits of proper argument handling.Consider this safer alternative that preserves arguments without eval:
run_cmd() { if [ "$DRY_RUN" = true ]; then echo "[DRY-RUN] $*" else echo "▶ $*" - eval "$@" + "$@" fi }Note: If you need shell metacharacter expansion (pipes, redirects, etc.), the current
evalapproach is necessary, but be aware it requires careful input sanitization.lib/demo_scripts/config.rb (2)
21-31: Add error handling for file reading.
File.readlineswill raise an exception if the file becomes unreadable between the existence check and the read operation (TOCTOU issue), or if there are permission issues.Apply this diff to add error handling:
def load_config - File.readlines(@config_file).each do |line| - next if line.strip.empty? || line.strip.start_with?('#') - - if line =~ /^SHAKAPACKER_VERSION\s*=\s*["'](.+)["']/ - @shakapacker_version = ::Regexp.last_match(1) - elsif line =~ /^REACT_ON_RAILS_VERSION\s*=\s*["'](.+)["']/ - @react_on_rails_version = ::Regexp.last_match(1) + File.readlines(@config_file).each do |line| + next if line.strip.empty? || line.strip.start_with?('#') + + if line =~ /^SHAKAPACKER_VERSION\s*=\s*["'](.+)["']/ + @shakapacker_version = ::Regexp.last_match(1) + elsif line =~ /^REACT_ON_RAILS_VERSION\s*=\s*["'](.+)["']/ + @react_on_rails_version = ::Regexp.last_match(1) + end + end +rescue Errno::EACCES, Errno::ENOENT => e + # File became inaccessible; silently fall back to defaults + warn "Warning: Could not read config file #{@config_file}: #{e.message}" if ENV['DEBUG'] +end + +private + +def load_config + begin + File.readlines(@config_file).each do |line| + next if line.strip.empty? || line.strip.start_with?('#') + + if line =~ /^SHAKAPACKER_VERSION\s*=\s*["'](.+)["']/ + @shakapacker_version = ::Regexp.last_match(1) + elsif line =~ /^REACT_ON_RAILS_VERSION\s*=\s*["'](.+)["']/ + @react_on_rails_version = ::Regexp.last_match(1) + end end + rescue Errno::EACCES, Errno::ENOENT => e + # Silently fall back to defaults, optionally warn in debug mode + warn "Warning: Could not read #{@config_file}: #{e.message}" if ENV['DEBUG'] end end
25-28: Regex patterns could be stricter.The regex patterns allow any characters within quotes (
.+), which could match malformed input or excessively long strings.Consider using a more restrictive pattern:
- if line =~ /^SHAKAPACKER_VERSION\s*=\s*["'](.+)["']/ + if line =~ /^SHAKAPACKER_VERSION\s*=\s*["']([~>= \d.]+)["']/ @shakapacker_version = ::Regexp.last_match(1) - elsif line =~ /^REACT_ON_RAILS_VERSION\s*=\s*["'](.+)["']/ + elsif line =~ /^REACT_ON_RAILS_VERSION\s*=\s*["']([~>= \d.]+)["']/ @react_on_rails_version = ::Regexp.last_match(1) endThis limits matches to valid gem version specifiers (digits, dots, and version operators).
bin/new-demo (1)
35-41: Comma-separated argument parsing may silently accept malformed input.The
split(',').map(&:strip)approach doesn't validate that arguments are well-formed Rails/React on Rails options. For example,--rails-args="--skip-test,,--api"would create an empty string element.Consider filtering out empty strings:
opts.on('--rails-args ARGS', 'Additional arguments to pass to rails new (comma-separated)') do |args| - options[:rails_args] = args.split(',').map(&:strip) + options[:rails_args] = args.split(',').map(&:strip).reject(&:empty?) end opts.on('--react-on-rails-args ARGS', 'Additional arguments to pass to react_on_rails:install (comma-separated)') do |args| - options[:react_on_rails_args] = args.split(',').map(&:strip) + options[:react_on_rails_args] = args.split(',').map(&:strip).reject(&:empty?) endlib/demo_scripts/pre_flight_checks.rb (1)
36-41: Handle repos with no initial commit.git diff-index HEAD fails on repos without HEAD. Prefer “git status --porcelain” to detect a clean tree.
- def check_uncommitted_changes! - if system('git diff-index --quiet HEAD -- 2>/dev/null') + def check_uncommitted_changes! + if `git status --porcelain 2>/dev/null`.strip.empty? puts '✓ No uncommitted changes' if @verbose return endlib/demo_scripts/demo_scaffolder.rb (1)
79-91: Prefer argv arrays with CommandRunner to avoid shell quoting issues.Once CommandRunner supports argv/chdir, pass arguments as arrays for safety. Example changes:
- @runner.run!( - "bundle exec rails generate react_on_rails:install #{all_args}", - dir: @demo_dir - ) + @runner.run!(["bundle", "exec", "rails", "generate", "react_on_rails:install", *all_args.split(' ')], dir: @demo_dir)- @runner.run!( - 'npm install --save-dev typescript @types/react @types/react-dom', - dir: @demo_dir - ) + @runner.run!(["npm", "install", "--save-dev", "typescript", "@types/react", "@types/react-dom"], dir: @demo_dir)- @runner.run!( - 'npm install --save-dev tailwindcss postcss autoprefixer', - dir: @demo_dir - ) - @runner.run!('npx tailwindcss init -p', dir: @demo_dir) + @runner.run!(["npm", "install", "--save-dev", "tailwindcss", "postcss", "autoprefixer"], dir: @demo_dir) + @runner.run!(["npx", "tailwindcss", "init", "-p"], dir: @demo_dir)- @runner.run!('npm install bootstrap react-bootstrap', dir: @demo_dir) + @runner.run!(["npm", "install", "bootstrap", "react-bootstrap"], dir: @demo_dir)- @runner.run!( - 'npm install @mui/material @emotion/react @emotion/styled', - dir: @demo_dir - ) + @runner.run!(["npm", "install", "@mui/material", "@emotion/react", "@emotion/styled"], dir: @demo_dir)- @runner.run!('npm install', dir: @demo_dir) + @runner.run!(["npm", "install"], dir: @demo_dir)- @runner.run('bundle exec rubocop -a --fail-level error', dir: @demo_dir) + @runner.run(["bundle", "exec", "rubocop", "-a", "--fail-level", "error"], dir: @demo_dir)Also applies to: 93-105, 107-128, 130-134, 136-143, 145-149, 183-187
lib/demo_scripts/demo_updater.rb (3)
86-101: Use argv arrays for bundle add (align with safer CommandRunner).Preps for the safer CommandRunner.

🔇 Additional comments (45)
.rspec (1)
1-3: LGTM! Standard RSpec configuration.The configuration correctly enables spec_helper auto-require, colored output, and documentation formatting, which are standard best practices for RSpec projects.
packages/demo_common/lib/demo_common/version.rb (1)
1-5: LGTM! Standard version constant definition.The version module follows Ruby conventions with frozen string literal and a semantic version constant, appropriate for the initial 0.1.0 release of the demo_common gem.
Gemfile.development_dependencies (3)
1-24: Well-structured shared dependencies file with clear documentation.The file provides a clean, centralized manifest for demo development dependencies with helpful usage instructions. The gem selections and version constraints are appropriate for a modern Rails/RSpec development environment.
13-16: Addresses duplication concern with root Gemfile.These rubocop gems (rubocop, rubocop-performance, rubocop-rspec) also appear in the root Gemfile. Since this file is intended to be loaded by demo applications via
eval_gemfile, and the root Gemfile serves the monorepo root, the duplication may be intentional. However, consider whether demos should exclusively use this shared file while the root uses a different set, or if consolidation is possible.
23-23: Retain thelistengem for Rails 7+ evented file watching. Rails 7 still expects and recommendslistenfor the ActiveSupport::EventedFileUpdateChecker in development.Likely an incorrect or invalid review comment.
spec/spec_helper.rb (1)
1-27: LGTM! Comprehensive and well-configured RSpec setup.The spec helper follows RSpec best practices with appropriate configurations for expectations, mocks, example persistence, monkey patching disabled, profiling, and randomized execution. The setup properly supports the new DemoScripts test suite.
Gemfile (1)
7-12: No action required: development dependencies file isn’t evaluated by the root Gemfile.
The root Gemfile doesn’t reference Gemfile.development_dependencies (no eval_gemfile) so overlapping gems live in separate contexts and won’t conflict.Likely an incorrect or invalid review comment.
docs/CONTRIBUTING_SETUP.md (1)
1-180: Documentation is comprehensive and well-structured.The setup guide covers all essential development tasks, from initial setup through git hooks, testing, linting, and troubleshooting. The inclusion of Lefthook configuration details and best practices is particularly valuable for new contributors.
packages/demo_common/lib/demo_common.rb (1)
1-22: LGTM! Clean module structure with path helpers.The module provides a clear public API for accessing package paths. The use of
Pathnameand conditional Railtie loading follows Ruby best practices..github/workflows/ci.yml (1)
10-124: CI workflow is well-structured for the monorepo.The workflow appropriately separates linting and testing concerns across demo_common and individual demos. The dynamic demo detection for PRs is a good approach for selective testing.
README.md (2)
31-46: Clarify where bundle install should be run.The prerequisites mention Ruby 3.3+, but the setup instructions show
bundle installwithout specifying the working directory. Should this be run from the repository root or frompackages/demo_common/?Consider adding a working directory comment:
```bash -# Install dependencies +# Install dependencies (run from repository root) bundle install
1-141: README provides clear guidance for monorepo navigation.The documentation effectively communicates the new monorepo structure, script-driven workflows, and version management. The distinction between Ruby and Bash scripts is helpful for users.
Rakefile (1)
1-14: LGTM! Clean integration of linting into the default test flow.The Rakefile now provides a unified test-and-lint workflow through the
defaulttask, with a convenienttestalias. Removing the dynamic task loading simplifies the build configuration.spec/demo_scripts/config_spec.rb (2)
16-60: LGTM!The tests properly cover custom version overrides, file-based config loading, and edge cases like comments and empty lines. The use of
Dir.mktmpdirensures proper cleanup and isolation.
62-79: LGTM!The test correctly validates that constructor-provided versions take precedence over config file values, and demonstrates partial override behavior (only
react_on_rails_versionis overridden whileshakapacker_versionis loaded from the file).bin/scaffold-demo (3)
1-20: LGTM!The executable setup is clean with proper requires and well-structured default options. All flags are explicitly initialized.
22-82: LGTM!The option parsing is well-structured with clear help text and examples. The handling of comma-separated arguments with
split(',').map(&:strip)is appropriate for CLI input.
84-107: LGTM!The main execution flow properly validates that a demo name is provided, initializes the scaffolder with the parsed options, and handles both application errors (
DemoScripts::Error) and option parsing errors appropriately. Exit status 1 is correctly used for all error conditions.lib/demo_scripts.rb (2)
1-9: LGTM!The require structure is clean and well-organized, loading core components (version, config) before higher-level functionality (creators, scaffolders, updater).
11-16: LGTM!The exception hierarchy is well-designed with a base
Errorclass inheriting fromStandardError(Ruby best practice) and specialized error types (PreFlightCheckError,CommandError) for different failure modes, enabling precise error handling in client code.spec/demo_scripts/pre_flight_checks_spec.rb (4)
1-19: LGTM!The test setup properly isolates each test with cleanup in both
beforeandafterblocks. Usingverbose: falseprevents output pollution during test runs.
32-43: LGTM!The test properly validates that an existing directory triggers a
PreFlightCheckError. The regex matcher allows for flexible message matching.
45-56: LGTM!The test correctly stubs the git repository check and validates the expected error. Using a regex for the command allows flexibility in the exact git command format.
58-71: LGTM!The test correctly simulates being in a git repository with uncommitted changes by stubbing both
git rev-parse(returns true) andgit diff-index(returns false). This properly validates the uncommitted changes check.spec/demo_scripts/demo_creator_spec.rb (5)
1-21: LGTM!The initialization test provides good baseline coverage, verifying that a
DemoCreatorcan be instantiated with the expected options.
23-42: LGTM!The tests properly validate dry-run mode behavior: output indicates dry-run status and no demo directory is created. Using
skip_pre_flight: trueappropriately avoids git state dependencies in unit tests.
44-61: LGTM!The test appropriately uses
sendto access the privategenerate_readme_contentmethod for validation. It correctly verifies that gem versions and the version header are included in the generated README.
63-68: LGTM!The test correctly validates that the creation date in
YYYY-MM-DDformat is included in the generated README.
70-75: LGTM!The test validates that the README includes a link to the version management documentation, ensuring discoverability of important documentation for demo users.
scripts/new-demo.sh (3)
83-88: Good validation and pre-flight checks!The demo name validation prevents path traversal, and the comprehensive pre-flight checks (directory existence, git status, git repository) prevent common errors. This addresses the concerns from previous reviews.
Also applies to: 109-134
204-209: JS dependency installation is now included.The script correctly installs JavaScript dependencies after running the installers, addressing the previous review concern. The conditional check for

packages/demo_common/lib/generators/demo_common/install/install_generator.rb (9)
12-15: Verify error handling for npm command.The
runmethod doesn't halt the generator on command failure by default. If npm is unavailable or the path is invalid, the installation will continue silently.Consider whether explicit error checking is needed:

17-22: Verify error handling for sequential commands.Multiple shell commands are executed without checking for failures. If npm or lefthook is unavailable, or if any command fails, subsequent commands may produce unexpected results.
24-32: LGTM!The RuboCop configuration creation is well-structured with proper YAML formatting and clear guidance for project-specific overrides.
34-44: LGTM!The ESLint configuration follows a good pattern for extending shared config with clear guidance for project-specific overrides.

Validate demo name before passing to DemoCreator.

Add demo name validation in bin/new-demo
The CLI currently accepts any string as DEMO_NAME and neither DemoCreator nor PreFlightChecks enforce a valid format or sanitize path inputs. Add a validation step in bin/new-demo—for example, enforce something like /\A[a-zA-Z0-9_-]+\z/—and exit early with a clear error if the name is invalid.
🤖 Prompt for AI Agents
In bin/new-demo around lines 62 to 69, the script currently passes any demo_name
from ARGV[0] into DemoCreator; add a validation step before constructing
DemoCreator that checks ARGV[0] exists and matches the allowed pattern (for
example /\A[a-zA-Z0-9_-]+\z/), and if it fails print a clear error to STDERR and
exit with a nonzero status; ensure this validation occurs before any filesystem
or creator actions so invalid names are rejected early (optionally also enforce
a max length and reject values containing path separators to prevent traversal).

Run pre-commit commands sequentially when they git add.
With parallel: true, Lefthook can launch trailing-newline and rubocop at the same time. Both commands ultimately execute git add (explicitly in the newline fixer and implicitly via stage_fixed: true), so they’ll race on .git/index and intermittently fail with “index.lock” errors. Flip the block back to sequential execution (or move the newline fixer into a separate serial block) so only one command touches the index at a time.
Apply this diff:
pre-commit:
- parallel: true
+ parallel: false🤖 Prompt for AI Agents
In lefthook.yml around lines 5 to 27, running commands in parallel causes races
on git index because both trailing-newline (which calls git add) and rubocop
(which uses stage_fixed) can touch .git/index concurrently; change execution to
sequential by removing or setting parallel to false for this block (or move the
trailing-newline hook into a separate serial block) so only one command performs
git add at a time, preventing intermittent index.lock errors.

Handle staged paths with spaces.
for file in {staged_files}; do splits on whitespace, so a staged file like docs/Release Notes.md is never processed and the hook silently fails to add the newline. Read the staged list with a NUL‑delimited loop (via git diff --cached --name-only -z) to preserve spaces and other special characters.

In lefthook.yml around lines 10 to 21, the current for-loop splits staged file
paths on whitespace so files with spaces are skipped; replace the iteration with
a NUL-delimited read loop that obtains staged paths using git diff --cached
--name-only -z and then uses while IFS= read -r -d '' file; do ... done to
handle filenames with spaces and special characters safely, keeping the same
checks (ensure file exists, check trailing newline with tail -c 1, append a
newline when missing, and git add the modified file) and ensure all uses of
$file are properly quoted.

Add error handling for JSON parsing and consider merge behavior.
Two concerns:
JSON.parsewill raise an exception if package.json is malformed, halting the generator unexpectedly.merge!will silently overwrite any existing scripts with the same keys. Consider whether this is intentional or if you should preserve existing scripts.

In scripts/new-demo.sh around line 85, the echo uses undefined color variables
${RED} and ${NC}; define ANSI color variables (e.g., RED and NC/reset) near the
top of the script (or before use) so they are non-empty and safe, e.g., add
assignments like RED='\033[0;31m' and NC='\033[0m' (or wrap in a conditional to

Reject demo names starting with “-”. Allowing a leading hyphen means every subsequent cd '$DEMO_DIR' is interpreted as an option (cd -foo), so the scaffold fails immediately after rails new. Add an explicit guard so names beginning with - are rejected up front.

In scripts/scaffold-demo.sh around lines 69 to 74, the demo name validation
currently allows names that begin with a hyphen which causes commands like cd to
treat them as options; add an explicit guard rejecting names that start with '-'
(for example check if DEMO_NAME begins with '-' and fail with the same error
message), ensuring the script exits with status 1 when a leading hyphen is
detected.

Rename the entire package to use the full shakacode_demo_common name consistently across the codebase for better clarity and to avoid generic naming conflicts. Changes: - Rename packages/demo_common/ to packages/shakacode_demo_common/ - Update gem name from 'demo_common' to 'shakacode_demo_common' - Update module name from DemoCommon to ShakacodeDemoCommon - Rename all lib/ files and directories to use shakacode_demo_common - Update all require statements and references in Ruby code - Update all bash scripts to reference the new package name - Update documentation (README.md, CONTRIBUTING.md, etc.) - Update rake tasks namespace from :demo_common to :shakacode_demo_common - Update .rubocop.yml to reference new directory and remove unused plugins This ensures the gem name matches the directory name convention where both use underscores (shakacode_demo_common), following Ruby best practices. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
Remove backslash escape from $CURRENT_DATE to allow proper variable expansion in generated README files. Without this fix, the literal text "$CURRENT_DATE" would appear instead of the actual date.

Pull Request Review: Monorepo Structure SetupSummaryThis is an excellent foundation for a monorepo structure supporting multiple React on Rails demo applications. The PR demonstrates strong engineering practices with comprehensive tooling, testing, documentation, and automation. The conversion from bash to Ruby scripts with full test coverage is particularly impressive. ✅ StrengthsArchitecture & Design
Code Quality
Documentation
Security
🔍 Areas for Improvement1. Security - Path Traversal Validation (Priority: HIGH)Issue: While the PR description mentions path traversal protection, I do not see explicit validation in the code. Location: Concern: A malicious demo name like Recommendation: Add explicit validation for demo names to prevent path traversal attacks. 2. Code Quality - Logic Bug in PreFlightChecks (Priority: MEDIUM)Issue: Incorrect logic in target directory check at The method returns early if directory exists, but then tries to print success message which is never executed. The logic should check if directory exists first, raise error, then print success message. 3. Testing - Missing Edge Cases (Priority: MEDIUM)Gaps identified:
🎯 Test Coverage AssessmentOverall: Good (estimated 75-80% coverage of critical paths) Well-covered: Config loading, command runner dry-run, pre-flight checks for git state 🔒 Security AssessmentOverall: Good with one critical gap Critical Gap: Missing path traversal validation for demo names 📋 Recommendations SummaryMust Fix (before merge)
Should Fix (can be follow-up PR)
Nice to Have
✨ Final ThoughtsThis is production-ready code with minor issues to address. The thoughtful architecture, comprehensive testing, excellent documentation, and developer-friendly tooling make this an exemplary monorepo setup. Recommendation: ✅ Approve with minor changes Fix the two must-fix items (path validation and logic bug), and this will be an excellent foundation for the React on Rails demos repository.

if ARGV.empty? puts parser exit 1 end + demo_name = ARGV[0] + + # Validate demo name format + unless demo_name.match?(/\A[a-zA-Z0-9_-]+\z/) && demo_name.length <= 100 + warn "Error: Invalid demo name '#{demo_name}'" + warn "Demo name must contain only letters, numbers, hyphens, and underscores (max 100 chars)" + exit 1 + end + - demo_name = ARGV[0] - creator = DemoScripts::DemoCreator.new(This check should happen before any DemoCreator instantiation to prevent path traversal attacks.
.github/workflows/ci.yml (2)
65-70: Don’t mask ESLint/Prettier failures; use --if-present instead of continue-on-error.
Currently failures are ignored and scripts may not exist in the package. Make failures actionable while remaining optional.Apply this diff:

55-73: Add error handling for JSON parsing and consider merge behavior.Two concerns remain from previous reviews:

🧹 Nitpick comments (21)
packages/shakacode_demo_common/shakacode_demo_common.gemspec (2)
6-13: Add helpful gem metadata URIs.Improve discoverability on RubyGems by adding source, docs, and changelog links.

25-27: Ensure a license file is present
Add aLICENSE(or rename yourMIT-LICENSE) inpackages/shakacode_demo_commonand update the gemspec paths if necessary.scripts/test-all.sh (3)
48-60: Tighten Rails detection and guard RuboCop.Use executable check for Rails and only run RuboCop when a Gemfile exists to avoid false failures in non-Rails demos.
- if [ -f "bin/rails" ]; then + if [ -x "bin/rails" ]; then if [ -d "spec" ]; then echo " Running RSpec tests..." bundle exec rspec || FAILED_DEMOS="$FAILED_DEMOS $demo_name" elif [ -d "test" ]; then echo " Running Rails tests..." bin/rails test || FAILED_DEMOS="$FAILED_DEMOS $demo_name" fi - # Run RuboCop - echo " Running RuboCop..." - bundle exec rubocop || FAILED_DEMOS="$FAILED_DEMOS $demo_name-rubocop" + # Run RuboCop + if [ -f "Gemfile" ]; then + echo " Running RuboCop..." + bundle exec rubocop || FAILED_DEMOS="$FAILED_DEMOS $demo_name-rubocop" + fi fi
39-45: Handle demo paths with spaces (optional).Current glob can split on spaces. Consider a nullglob + loop or find -print0 for robustness.
-if [ -d "demos" ] && [ "$(ls -A demos 2>/dev/null)" ]; then - for demo in demos/*; do +shopt -s nullglob +if [ -d "demos" ] && compgen -G "demos/*" >/dev/null; then + for demo in demos/*; do if [ -d "$demo" ]; then
29-33: Detect pnpm when present (keeps PR’s “npm/pnpm support” promise).Prefer pnpm if pnpm-lock.yaml exists; fall back to npm.
- echo " Running JavaScript tests..." - if ! npm test; then + PM="npm"; [ -f "pnpm-lock.yaml" ] && PM="pnpm" + echo " Running JavaScript tests with $PM..." + if ! $PM test; then FAILED_DEMOS="$FAILED_DEMOS shakacode_demo_common-js" fi - if ! npm run lint; then + if ! $PM run lint; then FAILED_DEMOS="$FAILED_DEMOS shakacode_demo_common-eslint" fi- echo " Running JavaScript tests..." - if ! npm test; then + PM="npm"; [ -f "pnpm-lock.yaml" ] && PM="pnpm" + echo " Running JavaScript tests with $PM..." + if ! $PM test; then FAILED_DEMOS="$FAILED_DEMOS ${demo_name}-js" fi - if ! npm run lint; then + if ! $PM run lint; then FAILED_DEMOS="$FAILED_DEMOS ${demo_name}-eslint" fiAlso applies to: 64-67

6-12: Prettier setup looks fine; consider minor hardening.Optional:
- Add a .prettierignore for build/coverage/tmp to avoid accidental walks.
- Consider bumping Prettier to latest 3.x and adding an engines.node constraint for consistency across contributors.

-🤖 Generated with [Claude Code](https://claude.com/claude-code) - -Co-Authored-By: Claude <[email protected]>.new-demo-versions (1)
10-13: Consider documenting the version constraint format.The pessimistic version constraints (
~> 8.0,~> 16.0) are standard Ruby gem syntax, but the file format mixing shell-style comments with gem version syntax may be confusing. Consider adding a note explaining that these follow Ruby gem version constraint conventions if they're consumed by Ruby code, or converting to a format more appropriate for the actual consumer (e.g., YAML, JSON, or pure shell variables).bin/update-all-demos (2)
60-64: Consider validating that at least one version is specified.The script allows execution without specifying
--react-on-rails-versionor--shakapacker-version, which would result in no updates being performed. Consider adding a check to ensure at least one version option is provided before instantiating the updater, or document this as expected behavior if DemoUpdater handles it gracefully.begin parser.parse! + + if options[:react_on_rails_version].nil? && options[:shakapacker_version].nil? + warn "Error: At least one of --react-on-rails-version or --shakapacker-version must be specified" + puts parser + exit 1 + end updater = DemoScripts::DemoUpdater.new(**options) updater.update!
44-46: Document glob pattern constraints for the --demos option.The
--demosoption accepts an arbitrary glob pattern without validation. While glob patterns are powerful, consider adding a usage note in the help text about expected patterns (e.g.,'*typescript*','demo-v16-*') to guide users and prevent confusion with unexpected pattern matching behavior.- opts.on('--demos PATTERN', 'Only update demos matching pattern (glob)') do |pattern| + opts.on('--demos PATTERN', 'Only update demos matching pattern (glob, e.g., "*typescript*")') do |pattern| options[:demo_pattern] = pattern endbin/scaffold-demo (1)
70-76: Consider alternative parsing for arguments containing commas.The
--rails-argsand--react-on-rails-argsoptions split on commas (lines 71, 75), which will break if any argument value contains a comma. Consider using a different delimiter (e.g., space or semicolon) or accepting multiple instances of the flag instead.- opts.on('--rails-args ARGS', 'Additional arguments to pass to rails new (comma-separated)') do |args| - options[:rails_args] = args.split(',').map(&:strip) + opts.on('--rails-args ARGS', 'Additional arguments to pass to rails new (space-separated, quoted if needed)') do |args| + options[:rails_args] = args.split(/\s+/) end - opts.on('--react-on-rails-args ARGS', 'Additional arguments to pass to react_on_rails:install (comma-separated)') do |args| - options[:react_on_rails_args] = args.split(',').map(&:strip) + opts.on('--react-on-rails-args ARGS', 'Additional arguments to pass to react_on_rails:install (space-separated, quoted if needed)') do |args| + options[:react_on_rails_args] = args.split(/\s+/) endAlternatively, allow multiple flag instances:

36-44: Improve Gemfile modification robustness.Two concerns:
- Line 38:
grep -q "shakacode_demo_common"matches any occurrence, including comments or strings. This could skip adding the gem if it appears in a comment.- Lines 40-42: Appending without ensuring the file ends with a newline could cause formatting issues.
Apply this diff to make the check more precise and ensure proper formatting:
- if ! grep -q "shakacode_demo_common" "$demo/Gemfile"; then + if ! grep -q "^[[:space:]]*gem[[:space:]]*[\"']shakacode_demo_common[\"']" "$demo/Gemfile"; then echo " Adding shakacode_demo_common to Gemfile..." - echo '' >> "$demo/Gemfile" + # Ensure file ends with newline before appending + [ -n "$(tail -c1 "$demo/Gemfile")" ] && echo '' >> "$demo/Gemfile" + echo '' >> "$demo/Gemfile" echo '# Shared demo configuration and utilities' >> "$demo/Gemfile"scripts/new-demo.sh (3)
96-105: Avoid eval in run_cmd; preserve quoting safely.
eval is error‑prone for spaces/special chars. Use bash -lc and show colored prefixes.-run_cmd() { - if [ "$DRY_RUN" = true ]; then - echo "[DRY-RUN] $*" - else - echo "▶ $*" - eval "$@" - fi -} +run_cmd() { + if [ "$DRY_RUN" = true ]; then + echo -e "${YELLOW}[DRY-RUN]${NC} $*" + else + echo -e "${GREEN}▶${NC} $*" + bash -lc "$*" + fi +}Based on learnings (consistency with scaffold-demo.sh run_cmd).
116-135: Check “in git repo” before running git diff-index.
Current order can emit misleading errors if not in a repo (stderr hidden). Swap checks.-# Check 1: No uncommitted changes (staged or unstaged) -if ! git diff-index --quiet HEAD -- 2>/dev/null; then - echo "❌ Error: Repository has uncommitted changes" - ... - exit 1 -fi -echo "✓ No uncommitted changes" - -# Check if we're in a git repository -if ! git rev-parse --git-dir > /dev/null 2>&1; then - echo "❌ Error: Not in a git repository" - exit 1 -fi -echo "✓ In git repository" +# Check if we're in a git repository +if ! git rev-parse --git-dir > /dev/null 2>&1; then + echo "❌ Error: Not in a git repository" + exit 1 +fi +echo "✓ In git repository" + +# Check 1: No uncommitted changes (staged or unstaged) +if ! git diff-index --quiet HEAD --; then + echo "❌ Error: Repository has uncommitted changes" + ... + exit 1 +fi +echo "✓ No uncommitted changes"
203-209: Prefer reproducible JS installs.
Use pnpm if present; otherwise npm ci when lockfile exists, else npm install.-if command -v pnpm &> /dev/null; then - run_cmd "cd '$DEMO_DIR' && pnpm install" -else - run_cmd "cd '$DEMO_DIR' && npm install" -fi +if command -v pnpm >/dev/null 2>&1; then + run_cmd "cd '$DEMO_DIR' && pnpm install" +else + if [ -f "$DEMO_DIR/package-lock.json" ]; then + run_cmd "cd '$DEMO_DIR' && npm ci" + else + run_cmd "cd '$DEMO_DIR' && npm install" + fi +fipackages/shakacode_demo_common/package.json (3)
21-25: Ensure first-time publish works for scoped package.
Add publishConfig access: public; otherwise npm publish may fail."files": [ "configs/", "playwright/", "index.js" ], + "publishConfig": { + "access": "public" + },
37-44: Mark playwright peer as optional (avoid install warnings).
Many consumers won’t use Playwright directly."peerDependencies": { "playwright": "^1.35.0" }, + "peerDependenciesMeta": { + "playwright": { + "optional": true + } + },
6-9: Repository metadata should point to monorepo and package directory.
Set repository.url to the monorepo and add directory for clarity on npm."repository": { "type": "git", - "url": "https://github.com/shakacode/react-on-rails-demo-common.git" + "url": "https://github.com/shakacode/react_on_rails-demos.git", + "directory": "packages/shakacode_demo_common" },packages/shakacode_demo_common/Rakefile (1)
95-101: Make npm publish explicit for scoped public package.
Align with package.json publishConfig and avoid interactive failure.- sh 'npm publish' + sh 'npm publish --access public'lib/demo_scripts/demo_creator.rb (1)
57-73: Consider path safety in shell command construction.Line 72 uses single quotes around
@demo_dirin the shell command. While demo names are validated to contain only safe characters, consider usingShellwords.escapefor extra safety if validation ever changes.Optional refactor:
require 'shellwords' def create_rails_app puts '📦 Creating Rails application...' base_args = [ '--database=postgresql', '--skip-javascript', '--skip-hotwire', '--skip-action-mailbox', '--skip-action-text', '--skip-active-storage', '--skip-action-cable', '--skip-sprockets', '--skip-system-test', '--skip-turbolinks' ] all_args = (base_args + @rails_args).join(' ') @runner.run!("rails new #{Shellwords.escape(@demo_dir)} #{all_args}") endpackages/shakacode_demo_common/lib/generators/shakacode_demo_common/install/install_generator.rb (1)
17-22: Consider adding error handling for npm install commands.Each public method in a generator is executed sequentially, but the
runmethod for npm install commands (lines 14, 20-21) doesn't check exit status. If npm install fails (network issues, permission problems, etc.), the generator continues silently, potentially leaving the project in a broken state.Consider checking command success:
def copy_lefthook_config say 'Installing Lefthook configuration' copy_file lefthook_config_path, 'lefthook.yml' unless run 'npm install --save-dev lefthook @commitlint/cli @commitlint/config-conventional' say 'Warning: npm install failed for Lefthook dependencies', :yellow end unless run 'npx lefthook install' say 'Warning: Lefthook installation failed', :yellow end end

15-17: Retain current spec.files glob
The existing pattern packages onlylib/**/*,Rakefile, andREADME.md; no extraneous files are included, and switching togit ls-fileswould pull in dotfiles and other tracked files you likely don’t want in the gem.Likely an incorrect or invalid review comment.

Fix paths to renamed package directory (breaking).
Jobs still use packages/demo_common. The repo renamed to packages/shakacode_demo_common, so steps will run in a non-existent path and fail.

Verify script execution context and symlink target paths.
The symlink paths (../../packages/shakacode_demo_common/config/...) assume the script is executed from the repository root. If run from a different directory, the symlinks will point to incorrect locations.
