Code ReviewHi @justin808! I've reviewed PR #1944 for React 19 import consistency. Overall this is a solid improvement, but I found one critical bug that needs to be fixed before merging. 🐛 Critical Bug FoundFile: The PR updates most instances to use named imports, but line 91 still uses // Line 91 - NEEDS TO BE FIXED
return React.createElement(component as ReactComponent, props);Why this is critical:
Fix needed: // Should be:
return createElement(component as ReactComponent, props);Location: packages/react-on-rails/src/createReactOutput.ts:91 ✅ What's Good
🔍 Additional Observations1. Inconsistent import patterns remain in codebase: Other files still use namespace imports:
Recommendation: Consider a follow-up PR to standardize ALL React imports across the codebase, or document why some files intentionally use namespace imports (e.g., 2. Test coverage: I reviewed
3. Type imports: Good use of 📋 Security & Performance
🎯 RecommendationBlock merge until the bug on line 91 is fixed. After that fix:

This PR updates the open-source package to use the same import pattern
as the Pro package, ensuring consistency across the codebase.
## Changes
Changed from namespace imports to named imports in 3 OSS files:
**Before (inconsistent with Pro):**
```typescript
import * as React from 'react';
React.createElement()
React.isValidElement()
```
**After (consistent with Pro):**
```typescript
import { createElement, isValidElement } from 'react';
createElement()
isValidElement()
```
### Files Updated
1. `packages/react-on-rails/src/createReactOutput.ts`
- `React.createElement` → `createElement`
- `React.isValidElement` → `isValidElement`
- `React.ReactElement` type → `ReactElement` type
2. `packages/react-on-rails/src/handleError.ts`
- `React.createElement` → `createElement`
3. `packages/react-on-rails/src/serverRenderReactComponent.ts`
- `React.isValidElement` → `isValidElement`
- Consolidated duplicate ReactElement import
## Why This Matters
**Consistency:** Pro package (PR #1943) uses named imports. This brings OSS in line.
**React 19 Best Practice:** Named imports are the recommended pattern for React 19:
- Better tree-shaking
- Clearer dependencies
- More explicit code
**No Breaking Changes:** Both patterns work with React 18 and 19.
## Testing
✅ Builds successfully
✅ All existing tests pass
✅ No API changes
✅ Runtime behavior unchanged
## Dependencies
- Independent of PR #1942 and #1943
- Can merge in any order
- Purely a code style/consistency improvement
## Impact
- ✅ Improves codebase consistency
- ✅ Follows React 19 best practices
- ✅ No breaking changes
- ✅ Works with React 18 and 19

Code Review - PR #1944: Update OSS package imports for consistencySummaryThis PR updates the OSS package to use named imports from React instead of namespace imports, aligning with the Pro package and React 19 best practices. The changes are clean, focused, and non-breaking. ✅ Strengths1. Code Quality & Consistency
2. Best Practices
3. Testing & Validation
🔍 Observations & Minor Suggestions1. Test Files Still Use Old Pattern (Non-blocking)The test files still use namespace imports:
Suggestion: Consider updating test files in a follow-up PR for complete consistency. This is purely cosmetic and doesn't affect functionality. Rationale: While test files don't ship to users, maintaining consistency across the entire codebase (including tests) makes the codebase easier to maintain and sets a clear pattern for contributors. 2. Comments Still Reference Old Style (Documentation)Some comments still reference
Suggestion: Update comments to reflect the new import style or make them implementation-agnostic (e.g., "create a React element"). Rationale: Keeps documentation aligned with actual implementation. 🎯 Code AnalysiscreateReactOutput.tsChanges:
Analysis: Perfect. All usages properly replaced. handleError.tsChanges:
Analysis: Clean and minimal. This file is straightforward error handling. serverRenderReactComponent.tsChanges:
Analysis: Great cleanup! Removing the duplicate type import improves code quality. 🔒 Security & Performance
📊 Test CoverageCurrent state:
Recommendation: No additional tests needed - this is a refactor with identical behavior. 🚀 RecommendationsImmediate (This PR)✅ APPROVE & MERGE - This PR is ready to go! Follow-up (Future PRs)
🎉 ConclusionOverall Assessment: ⭐⭐⭐⭐⭐ (5/5) This is an excellent refactoring PR that:
Recommendation: APPROVE AND MERGE The minor observations about test files and comments are purely cosmetic and can be addressed in follow-up work if desired. They should NOT block this PR. 📝 Checklist (Per CLAUDE.md)Based on the project's CLAUDE.md requirements:

Summary
This is part 3 of the React 19 support effort - updates OSS package to use the same import pattern as Pro package for consistency.
Problem
Code review on PR #1943 found that the Pro package was updated to use named imports but the OSS package still used namespace imports, creating inconsistency:
Pro package (after #1943):
OSS package (before this PR):
Changes
Updated 3 OSS files to use named imports:
1.
createReactOutput.tsReact.createElement→createElementReact.isValidElement→isValidElementReact.ReactElement→ReactElementtype2.
handleError.tsReact.createElement→createElement3.
serverRenderReactComponent.tsReact.isValidElement→isValidElementWhy This Matters
✅ Consistency: Matches Pro package import style
✅ React 19 best practice: Named imports recommended for better tree-shaking
✅ Clearer code: Explicit about what's being used from React
✅ No breaking changes: Both patterns work identically in React 18 & 19
Testing
✅ Builds successfully
✅ All linting passes
✅ No API changes
✅ Runtime behavior unchanged
Dependencies
Independent - can merge in any order:
Impact
Follow-up
After all 3 PRs merge, the entire codebase will have consistent React import patterns!
