PR Review: Migrate to Shakapacker 9.0.0-beta.4 with Babel transpilerSummaryThis PR successfully migrates from Shakapacker 8.2.0 to 9.0.0-beta.4, but introduces a workaround for SSR issues that should be properly addressed before merging. ✅ Positive Aspects
🔴 Critical Issues1. SSR Workaround Instead of FixThe defensive programming pattern added to handle missing const formatMessage = intl && intl.formatMessage ? intl.formatMessage : (msg) => msg.defaultMessage || '';Issues with this approach:
Recommended fix: yarn add -D babel-plugin-formatjsThen update babel.config.js: plugins: [ ['formatjs', { idInterpolationPattern: '[sha512:contenthash:base64:6]', ast: true }], // ... other plugins ]2. Missing Test Coverage
🟡 Performance Considerations
🟡 Security Concerns
📝 Recommendations
🚦 VerdictRequest Changes - While the migration is technically correct, the SSR workaround should be replaced with a proper fix using babel-plugin-formatjs. The current approach creates technical debt and masks configuration issues. Consider creating a separate branch to properly configure babel-plugin-formatjs and test SSR functionality thoroughly before proceeding with the SWC migration. 🤖 Generated with Claude Code Co-Authored-By: Claude noreply@anthropic.com |

client/app/bundles/comments/components/CommentBox/CommentForm/CommentForm.jsx (1)
104-106: Consider extracting the SSR guard to eliminate duplication.The same SSR guard pattern for
formatMessageis repeated four times acrossformHorizontal,formStacked,formInline, andrender. This duplication increases maintenance burden and the risk of inconsistent updates.Consider extracting the guard logic to a helper method or computing it once in
renderand passing it to the form methods:Option 1: Extract to instance method
+ getFormatMessage() { + const { intl } = this.props; + return intl && intl.formatMessage ? intl.formatMessage : (msg) => msg.defaultMessage || ''; + } + formHorizontal() { - // Safeguard for SSR where intl might not be properly initialized - const { intl } = this.props; - const formatMessage = intl && intl.formatMessage ? intl.formatMessage : (msg) => msg.defaultMessage || ''; + const formatMessage = this.getFormatMessage(); return (Apply the same change to
formStacked,formInline, andrender.Option 2: Compute once in render and pass as parameter
render() { + const formatMessage = this.getFormatMessage(); let inputForm; switch (this.state.formMode) { case 0: - inputForm = this.formHorizontal(); + inputForm = this.formHorizontal(formatMessage); break;Then update each form method signature to accept
formatMessageas a parameter.Also applies to: 161-163, 218-220, 323-325

Gemfile (1)
9-9: LGTM! Version aligns with npm package.The gem version format (9.0.0.beta.4) correctly matches the npm package version (9.0.0-beta.4) from package.json. The beta version concern applies here as well—ensure thorough testing before production deployment.
config/shakapacker.yml (1)
11-11: LGTM! Babel transpiler configuration is explicit.The addition of
javascript_transpiler: babelclearly documents the transpilation strategy. This aligns with the existing Babel dependencies in package.json (babel-loader, @babel/core, etc.).Per the PR objectives, switching to SWC is planned as a follow-up. Consider opening a tracking issue for that migration if one doesn't exist yet.
client/app/bundles/comments/components/CommentBox/CommentBox.jsx (1)
77-78: LGTM! SSR-safe guard for intl is well-implemented.The fallback ensures
formatMessageis always callable, preventing runtime errors during SSR whenintlmight be uninitialized. The fallback correctly usesmsg.defaultMessage(from thedefaultMessagesimport on line 8) as a sensible default.This pattern is consistently applied across other components in this PR (CommentForm, SimpleCommentScreen).
client/app/bundles/comments/components/SimpleCommentScreen/ror_components/SimpleCommentScreen.jsx (1)
75-76: LGTM! Consistent SSR-safe implementation.The guard implementation is identical to the one in CommentBox.jsx (lines 77-78), ensuring consistency across components. The fallback chain (
msg.defaultMessage || '') handles edge cases gracefully.package.json (1)
96-96: Verify beta stability and migration plan.You're using Shakapacker 9.0.0-beta.4, but the latest stable release is 8.4.0. Version 9.0.0 has not reached GA and lacks official migration documentation. Ensure thorough testing in staging before deploying to production.
Track the official 9.0.0 release and review the migration guide once available. Consider the stability requirements of your production environment when using pre-release versions.
client/app/bundles/comments/components/CommentBox/CommentForm/CommentForm.jsx (1)
104-106: Clarify whenintlwould be unavailable.The component is wrapped with
injectIntl(line 371) and declaresintlas a required prop (line 19). Under normal circumstances with a properIntlProviderwrapper,intlshould always be available.Can you clarify the specific scenario where
intlorintl.formatMessagewould be unavailable?
- Is this addressing a case where the component is rendered outside of
IntlProvider?- Is this a temporary workaround for the babel-plugin-formatjs issue mentioned in the PR objectives?
- Should this guard be removed once the SWC transpiler migration is complete?
Understanding the specific use case will help determine if this is the right long-term solution or if there's a better approach (e.g., ensuring
IntlProvideralways wraps the component tree).

🧩 Analysis chain
Verify that empty string fallback is acceptable for SSR.
The SSR guard falls back to returning msg.defaultMessage || ''. While this prevents runtime errors, it may result in empty labels, placeholders, and button text during server-side rendering if defaultMessage is undefined.
Please verify that:
- All message descriptors in
defaultMessageshavedefaultMessageproperties defined - Empty strings during SSR won't negatively impact SEO or initial page render
- The client-side hydration correctly replaces these with proper localized messages
You can verify the message descriptor structure with:

Critical: Missing required file for import
The import import { defaultMessages } from 'libs/i18n/default'; on line 7 references a file that does not exist in the codebase. The file client/app/libs/i18n/default.js (or .ts, .jsx, .tsx) has never been committed to the repository.
This will cause a module resolution error at runtime, preventing the component from loading. The SSR fallback logic in lines 106, 163, 220, and 325 cannot be evaluated because the import itself will fail.
Required action:
- Create the missing
client/app/libs/i18n/default.jsfile with proper message descriptors - Ensure all message descriptors include both
idanddefaultMessageproperties:
import { defineMessages } from 'react-intl'; export const defaultMessages = defineMessages({ inputNameLabel: { id: 'comments.form.nameLabel', defaultMessage: 'Name' }, inputNamePlaceholder: { id: 'comments.form.namePlaceholder', defaultMessage: 'Enter your name' }, // ... other messages used in CommentForm.jsx });- After creating the file, verify that the fallback
msg.defaultMessage || ''provides acceptable UX during SSR
🤖 Prompt for AI Agents
In client/app/bundles/comments/components/CommentBox/CommentForm/CommentForm.jsx around line 106, the import of defaultMessages points to a missing module which will break module resolution; create the missing file client/app/libs/i18n/default.js exporting a defaultMessages object (use react-intl defineMessages or a plain object) and include message descriptors for every message used in CommentForm.jsx (each descriptor must have id and defaultMessage keys, e.g., inputNameLabel, inputNamePlaceholder, and any others referenced at lines ~106, 163, 220, 325); save the file and ensure the existing import statement matches the export name so the SSR fallback (msg.defaultMessage || '') can work correctly.

PR Review: Migrate to Shakapacker 9.0.0-beta.7Overall AssessmentThis is a well-structured migration PR with clear documentation and testing. The changes are focused and appropriate for a beta migration. Here's my detailed feedback: ✅ Strengths
🔍 Code Quality Issues1. Repeated Code Pattern - DRY Violation (Medium Priority)Location: All modified JSX files (CommentForm.jsx:104-106, 162-163, 218-220, 323-325, CommentBox.jsx:77-78, SimpleCommentScreen.jsx:75) Issue: The same intl safeguard is repeated 7 times across 3 files: const formatMessage = intl && intl.formatMessage ? intl.formatMessage : (msg) => msg.defaultMessage || '';Recommendation: Extract to a utility function or custom hook: // libs/i18n/helpers.js export const getFormatMessage = (intl) => intl?.formatMessage ?? ((msg) => msg.defaultMessage || ''); // Usage const formatMessage = getFormatMessage(intl);Rationale: Reduces maintenance burden, improves testability, and makes future changes easier. 2. Missing Import Issue (High Priority)Location: Multiple files import Issue: The file
Impact: This will cause runtime errors unless:
Recommendation: Verify this import path. If the file is missing, it must be created. If it's aliased, document this in the webpack config. 3. Incomplete Safeguarding (Medium Priority)Location: Issue: The Recommendation: Audit all components that use 🐛 Potential Bugs1. Unsafe Error Property Access (Medium Priority)Location: Issue: if (!error.error) return null;This assumes Fix: if (!error?.error) return null;2. HTML Input Type Issue (Low Priority)Location: Issue: Using Current: <input type="textarea" ... />Should be either: <input type="text" ... /> // single line // OR <textarea ... /> // multilineImpact: Browsers will treat this as 🔒 Security Considerations✅ No security concerns identified
Recommendation: Monitor Shakapacker 9.0.0 releases and upgrade from beta to stable as soon as available. ⚡ Performance Considerations
🧪 Test CoverageCurrent State: Limited test coverage for modified components
Recommendations:
Priority: Medium - While CI passes, the new SSR handling should have test coverage to prevent regressions. 📋 Additional Recommendations

This is the first of three planned PRs to migrate to Shakapacker 9.x: 1. Migrate to beta.4 with Babel transpiler (this PR) 2. Switch from Babel to SWC transpiler 3. Convert webpack configs to TypeScript Changes in this PR: - Updated Shakapacker from 8.2.0 to 9.0.0-beta.4 (both gem and npm package) - Configured javascript_transpiler: babel in shakapacker.yml - Temporarily disabled SSR due to react-intl compatibility issue Note: SSR is temporarily disabled due to a react-intl error that occurs with formatMessage when no id is provided. This appears to be related to babel-plugin-formatjs configuration. The app works correctly for client-side rendering and non-RouterApp pages still support SSR. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Re-enable SSR in React on Rails configuration - Add safeguards for formatMessage when intl context is not initialized during SSR - Add missing message definitions for form buttons - Update i18n translations to support all UI messages This fixes the react-intl SSR error that was preventing server-side rendering from working properly with Shakapacker 9.0.0-beta.4. 🤖 Generated with Claude Code (https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Update shakapacker gem to 9.0.0.beta.7 - Update shakapacker npm package to 9.0.0-beta.7 - Fix css-loader configuration for CSS modules compatibility - Beta.7 enables namedExport by default, which requires exportLocalsConvention to be 'camelCaseOnly' or 'dashesOnly' - Added configuration to automatically set exportLocalsConvention when namedExport is enabled This resolves the CI build error: "The modules.namedExport option requires the modules.exportLocalsConvention option to be camelCaseOnly or dashesOnly" 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
- Removed SSR safeguards from react-intl usage in JSX components - These safeguards were added during initial beta.4 migration - They're not necessary for the shakapacker v9 upgrade - Simplified code by using destructured formatMessage directly - Fixed failing Turbo/Stimulus inline form test - Added explicit wait time for Turbo frame update to complete - Test now properly waits for async Turbo frame navigation All tests passing (38 examples, 0 failures) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

- # Configure headless Chrome driver directly here - Capybara.register_driver :selenium_chrome_headless do |app| - options = Selenium::WebDriver::Chrome::Options.new - options.add_argument("--headless=new") - options.add_argument("--disable-gpu") - options.add_argument("--no-sandbox") - options.add_argument("--disable-dev-shm-usage") - options.add_argument("--window-size=1920,1080") - - Capybara::Selenium::Driver.new(app, browser: :chrome, options: options) - end - - Capybara::Screenshot.register_driver(:selenium_chrome_headless) do |js_driver, path| - js_driver.browser.save_screenshot(path) - end + # Register headless Chrome driver using the module + DriverRegistration.register_selenium_chrome_headlessOption 2: If inline registration is preferred, remove the unused
register_selenium_chrome_headlessmethod fromspec/support/driver_registration.rbto eliminate the duplication.

config/shakapacker.yml (1)
11-11: LGTM! Babel transpiler configuration added correctly.The addition of
javascript_transpiler: babelunder thedefaultblock is correct and will apply to all environments (development, test, production). This aligns with the PR objective to configure Babel as the JavaScript transpiler for Shakapacker 9.0.0-beta.7.config/webpack/commonWebpackConfig.js (1)
57-74: LGTM! CSS Modules configuration fix addresses the CI error correctly.The code correctly identifies the css-loader in the SCSS rule and sets
exportLocalsConvention: 'camelCaseOnly'whennamedExportis enabled. This fix resolves the CI error: "The modules.namedExport option requires the modules.exportLocalsConvention option to be camelCaseOnly or dashesOnly."The implementation follows the same defensive pattern as the sass-loader configuration above it, with proper type checks and index validation.
- Remove duplicate Chrome driver registration from rails_helper.rb - Centralize headless configuration in spec/support/driver_registration.rb - Update rails_helper to call DriverRegistration.register_selenium_chrome_headless - Clean up leftover empty object in CommentForm.jsx - Fix RuboCop string literal style violations This eliminates code duplication and ensures consistent headless configuration across the test suite. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

The removal of sassOptions: { includePaths: [] } may break Sass imports that rely on custom include paths. Consider verifying that all existing Sass imports continue to work without this configuration.

[nitpick] The comment mentions 'Force re-register' but doesn't explain why this is necessary. Consider adding more context about what specific configuration issues this addresses.

Pull Request Review - Shakapacker 9.0.0-beta.7 MigrationOverall AssessmentThis is a well-executed migration PR with good commit history, comprehensive testing notes, and clear documentation. The changes are focused and address the core requirements for upgrading to Shakapacker 9.0.0-beta.7. StrengthsCode Quality
Testing
Documentation
Code Review Issues1. Potential Null Reference Issue - CommentForm.jsx:104-105, 160-161, 216-217The intermediate intl variable adds an unnecessary indirection. While functionally equivalent to the previous code, this could potentially mask issues if intl is undefined. Severity: Low - The change does not introduce bugs, but questionable whether the refactor adds value. 2. Incomplete CSS Loader Validation - config/webpack/commonWebpackConfig.js:63-71The CSS loader configuration fix does not validate whether modules itself is enabled before checking namedExport. Severity: Low - Current code likely works but could be more defensive. 3. Deprecated Headless Flag - spec/support/driver_registration.rb:36Good fix! The migration from the old headless argument to --headless is correct. This implementation is appropriate for modern Chrome versions. 4. Driver Re-registration Pattern - spec/support/driver_registration.rb:5-6, 19, 32Force re-registering drivers by deleting them first could potentially cause issues in parallel test execution. Severity: Medium - Could cause test flakiness in certain scenarios. Performance ConsiderationsPositive Changes
The CSS loader configuration changes should have negligible performance impact. Security ConsiderationsNo Security Issues Found:
Minor Note: Using beta.7 in production should be carefully considered, but the PR description indicates this is part 1 of 3, which is appropriate. Test CoverageCoverage Assessment: Good Existing Coverage:

PR Review: Migrate to Shakapacker 9.0.0-beta.7 with Babel transpilerOverall AssessmentThis is a well-structured migration PR with clear objectives and good documentation. The changes are incremental, well-tested, and follow a logical progression through multiple commits. The PR successfully addresses the migration path from Shakapacker 8.2.0 to 9.0.0-beta.7. ✅ Strengths
🔍 Code Quality Observationsconfig/webpack/commonWebpackConfig.js (Lines 54-63)Potential Issue: The CSS loader fix may silently fail if the structure changes. const cssLoader = scssRule.use.find(loader => { const loaderName = typeof loader === 'string' ? loader : loader?.loader; return loaderName?.includes('css-loader'); }); if (cssLoader?.options?.modules?.namedExport) { cssLoader.options.modules.exportLocalsConvention = 'camelCaseOnly'; }Recommendation: Add defensive checks or logging to ensure the fix is actually applied: const cssLoader = scssRule.use.find(loader => { const loaderName = typeof loader === 'string' ? loader : loader?.loader; return loaderName?.includes('css-loader'); }); if (cssLoader?.options?.modules?.namedExport) { cssLoader.options.modules.exportLocalsConvention = 'camelCaseOnly'; } else if (cssLoader && !cssLoader.options?.modules) { // CSS loader found but modules not configured - might be expected console.debug('CSS loader found without modules configuration'); }Alternatively, consider if this configuration should be in a more centralized location or if Shakapacker 9.x has a built-in way to handle this. spec/support/driver_registration.rb (Lines 4-6, 18-19, 31-32)Concern: Force re-registering drivers by deleting them could cause issues in parallel test execution. def self.register_selenium_chrome # Force re-register to ensure our configuration is used Capybara.drivers.delete(:selenium_chrome)Questions:
Recommendation: Add a comment explaining why this is necessary, or consider using a check-and-register pattern: def self.register_selenium_chrome # Only register if not already configured to avoid redundant registrations return if Capybara.drivers[:selenium_chrome] && !ENV['FORCE_DRIVER_REREGISTER'] Capybara.register_driver :selenium_chrome do |app| Capybara::Selenium::Driver.new(app, browser: :chrome) end # ... rest of code endspec/support/driver_registration.rb (Line 36)Chrome Headless Flag: Using browser_options.args << "--headless"Note: The PR description mentions updating to Recommendation: Consider using browser_options.args << "--headless=new"🔒 Security Considerations
