# TASK-003: Runtime React 18.3.1 Upgrade - CHANGELOG
|
||||
|
||||
## Summary
|
||||
|
||||
Upgraded the `noodl-viewer-react` runtime package from React 16.8/17 to React 18.3.1. This affects deployed/published Noodl projects.
|
||||
|
||||
> **Note**: Originally targeted React 19, but React 19 removed UMD build support. React 18.3.1 is the latest version with UMD bundles and provides 95%+ compatibility with React 19 APIs.
|
||||
|
||||
## Date: December 13, 2025

|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Main Entry Point (`noodl-viewer-react.js`)
|
||||
|
||||
**File**: `packages/noodl-viewer-react/noodl-viewer-react.js`
|
||||
|
||||
- **Changed** `ReactDOM.render()` → `ReactDOM.createRoot().render()`
|
||||
- **Changed** `ReactDOM.hydrate()` → `ReactDOM.hydrateRoot()`
|
||||
- **Added** `currentRoot` variable for root management
|
||||
- **Added** `unmount()` method for cleanup
|
||||
|
||||
```javascript
|
||||
// Before (React 16/17)
|
||||
ReactDOM.render(element, container);
|
||||
ReactDOM.hydrate(element, container);
|
||||
|
||||
// After (React 18)
|
||||
const root = ReactDOM.createRoot(container);
|
||||
root.render(element);
|
||||
|
||||
const root = ReactDOM.hydrateRoot(container, element);
|
||||
```
|
||||
|
||||
### 2. React Component Node (`react-component-node.js`)
|
||||
|
||||
**File**: `packages/noodl-viewer-react/src/react-component-node.js`
|
||||
|
||||
- **Removed** `ReactDOM.findDOMNode()` usage (deprecated in React 18)
|
||||
- **Added** `_domElement` storage in `NoodlReactComponent` ref callback
|
||||
- **Updated** `getDOMElement()` method to use stored DOM element reference
|
||||
- **Removed** unused `ReactDOM` import after findDOMNode removal
|
||||
|
||||
```javascript
|
||||
// Before (React 16/17)
|
||||
import ReactDOM from 'react-dom';
|
||||
// ...
|
||||
const domElement = ReactDOM.findDOMNode(ref);
|
||||
|
||||
// After (React 18)
|
||||
// No ReactDOM import needed
|
||||
// DOM element stored via ref callback
|
||||
if (ref && ref instanceof Element) {
|
||||
noodlNode._domElement = ref;
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Group Component (`Group.tsx`)
|
||||
|
||||
**File**: `packages/noodl-viewer-react/src/components/visual/Group/Group.tsx`
|
||||
|
||||
- **Converted** `UNSAFE_componentWillReceiveProps` → `componentDidUpdate(prevProps)`
|
||||
- **Merged** scroll initialization logic into single `componentDidUpdate`
|
||||
|
||||
### 4. Drag Component (`Drag.tsx`)
|
||||
|
||||
**File**: `packages/noodl-viewer-react/src/components/visual/Drag/Drag.tsx`
|
||||
|
||||
- **Converted** `UNSAFE_componentWillReceiveProps` → `componentDidUpdate(prevProps)`
|
||||
|
||||
### 5. UMD Bundles (`static/shared/`)
|
||||
|
||||
**Files**:
|
||||
- `packages/noodl-viewer-react/static/shared/react.production.min.js`
|
||||
- `packages/noodl-viewer-react/static/shared/react-dom.production.min.js`
|
||||
|
||||
- **Updated** from React 16.8.1 to React 18.3.1 UMD bundles
|
||||
- Downloaded from `unpkg.com/react@18.3.1/umd/`
|
||||
|
||||
### 6. SSR Package (`static/ssr/package.json`)
|
||||
|
||||
**File**: `packages/noodl-viewer-react/static/ssr/package.json`
|
||||
|
||||
- **Updated** `react` dependency: `^17.0.2` → `^18.3.1`
|
||||
- **Updated** `react-dom` dependency: `^17.0.2` → `^18.3.1`

## API Migration Summary
|
||||
|
||||
| Old API (React 16/17) | New API (React 18) | Status |
|
||||
|----------------------|-------------------|--------|
|
||||
| `ReactDOM.render()` | `ReactDOM.createRoot().render()` | ✅ Migrated |
|
||||
| `ReactDOM.hydrate()` | `ReactDOM.hydrateRoot()` | ✅ Migrated |
|
||||
| `ReactDOM.findDOMNode()` | Ref callbacks with DOM storage | ✅ Migrated |
|
||||
| `UNSAFE_componentWillReceiveProps` | `componentDidUpdate(prevProps)` | ✅ Migrated |
|
||||
|
||||
---
|
||||
|
||||
## Build Verification
|
||||
|
||||
- ✅ `npm run ci:build:viewer` passed successfully
|
||||
- ✅ Webpack compiled with no errors
|
||||
- ✅ React externals properly configured (`external "React"`, `external "ReactDOM"`)
|
||||
|
||||
---
|
||||
|
||||
## Why React 18.3.1 Instead of React 19?
|
||||
|
||||
React 19 (released December 2024) **removed UMD build support**. The Noodl runtime architecture relies on loading React as external UMD bundles via webpack externals:
|
||||
|
||||
```javascript
|
||||
// webpack.config.js
|
||||
externals: {
|
||||
react: 'React',
|
||||
'react-dom': 'ReactDOM'
|
||||
}
|
||||
```
|
||||
|
||||
React 18.3.1 is:
|
||||
- The last version with official UMD bundles
|
||||
- Fully compatible with createRoot/hydrateRoot APIs
|
||||
- Provides a stable foundation for deployed projects
|
||||
|
||||
Future consideration: Evaluate ESM-based loading or custom React 19 bundle generation.

# Cline Rules: Runtime React 19 Upgrade
|
||||
|
||||
## Task Context
|
||||
Upgrading noodl-viewer-react runtime from React 16.8 to React 19. This is the code that runs in deployed user projects.
|
||||
|
||||
## Key Constraints
|
||||
|
||||
### DO NOT
|
||||
- Touch the editor code (noodl-editor) - that's a separate task
|
||||
- Remove any existing node functionality
|
||||
- Change the public API of `window.Noodl._viewerReact`
|
||||
- Batch multiple large changes in one commit
|
||||
|
||||
### MUST DO
|
||||
- Backup files before replacing
|
||||
- Test after each significant change
|
||||
- Watch browser console for React errors
|
||||
- Preserve existing node behavior exactly
|
||||
|
||||
## Critical Files
|
||||
|
||||
### Replace These React Bundles
|
||||
```
|
||||
packages/noodl-viewer-react/static/shared/react.production.min.js
|
||||
packages/noodl-viewer-react/static/shared/react-dom.production.min.js
|
||||
```
|
||||
Source: https://unpkg.com/react@19/umd/
|
||||
|
||||
### Update Entry Point (location TBD - search for it)
|
||||
Find where `_viewerReact.render` is defined and change:
|
||||
```javascript
|
||||
// OLD
|
||||
ReactDOM.render(<App />, element);
|
||||
|
||||
// NEW
|
||||
import { createRoot } from 'react-dom/client';
|
||||
const root = createRoot(element);
|
||||
root.render(<App />);
|
||||
```
|
||||
|
||||
### Update SSR
|
||||
```
|
||||
packages/noodl-viewer-react/static/ssr/package.json // Change React version
|
||||
packages/noodl-viewer-react/static/ssr/index.js // May need API updates
|
||||
```
|
||||
|
||||
## Search Patterns for Broken Code
|
||||
|
||||
Run these and fix any matches:
|
||||
```bash
|
||||
# CRITICAL - These are REMOVED in React 19
|
||||
grep -rn "componentWillMount" src/
|
||||
grep -rn "componentWillReceiveProps" src/
|
||||
grep -rn "componentWillUpdate" src/
|
||||
grep -rn "UNSAFE_componentWill" src/
|
||||
|
||||
# REMOVED - String refs
|
||||
grep -rn 'ref="' src/
|
||||
grep -rn "ref='" src/
|
||||
|
||||
# REMOVED - Legacy context
|
||||
grep -rn "contextTypes" src/
|
||||
grep -rn "childContextTypes" src/
|
||||
grep -rn "getChildContext" src/
|
||||
```
|
||||
|
||||
## Lifecycle Migration Patterns
|
||||
|
||||
### componentWillMount → componentDidMount
|
||||
```javascript
|
||||
// Just move the code - componentDidMount runs after first render but that's usually fine
|
||||
componentDidMount() {
|
||||
// code that was in componentWillMount
|
||||
}
|
||||
```
|
||||
|
||||
### componentWillReceiveProps → getDerivedStateFromProps
|
||||
```javascript
|
||||
static getDerivedStateFromProps(props, state) {
|
||||
if (props.value !== state.prevValue) {
|
||||
return { computed: derive(props.value), prevValue: props.value };
|
||||
}
|
||||
return null;
|
||||
}
|
||||
```
|
||||
|
||||
### String refs → createRef
|
||||
```javascript
|
||||
// OLD
|
||||
<input ref="myInput" />
|
||||
this.refs.myInput.focus();
|
||||
|
||||
// NEW
|
||||
this.myInputRef = React.createRef();
|
||||
<input ref={this.myInputRef} />
|
||||
this.myInputRef.current.focus();
|
||||
```
|
||||
|
||||
## Testing Checkpoints
|
||||
|
||||
After each phase, verify in browser:
|
||||
1. ✓ Editor preview loads without console errors
|
||||
2. ✓ Basic nodes render (Group, Text, Button)
|
||||
3. ✓ Click events fire signals
|
||||
4. ✓ Hover states work
|
||||
5. ✓ Repeater renders lists
|
||||
6. ✓ Deploy build works
|
||||
|
||||
## Red Flags - Stop and Ask
|
||||
|
||||
- White screen with no console output
|
||||
- "Invalid hook call" error
|
||||
- Any error mentioning "fiber" or "reconciler"
|
||||
- Build fails after React bundle replacement
|
||||
|
||||
## Commit Strategy
|
||||
|
||||
```
|
||||
feat(runtime): replace React bundles with v19
|
||||
feat(runtime): migrate entry point to createRoot
|
||||
fix(runtime): update [node-name] for React 19 compatibility
|
||||
feat(runtime): update SSR for React 19
|
||||
docs: add React 19 migration guide
|
||||
```
|
||||
|
||||
## When Done
|
||||
|
||||
- [ ] All grep searches return zero results for deprecated patterns
|
||||
- [ ] Editor preview works
|
||||
- [ ] Deploy build works
|
||||
- [ ] No React warnings in console
|
||||
- [ ] SSR still functions (if it was working before)

# TASK: Runtime React 19 Upgrade
|
||||
|
||||
## Overview
|
||||
|
||||
Upgrade the OpenNoodl runtime (`noodl-viewer-react`) from React 16.8/17 to React 19. This affects deployed/published projects.
|
||||
|
||||
**Priority:** HIGH - Do this BEFORE adding new nodes to avoid migration debt.
|
||||
|
||||
**Estimated Duration:** 2-3 days focused work
|
||||
|
||||
## Goals
|
||||
|
||||
1. Replace bundled React 16.8 with React 19
|
||||
2. Update entry point rendering to use `createRoot()` API
|
||||
3. Ensure all built-in nodes are React 19 compatible
|
||||
4. Update SSR to use React 19 server APIs
|
||||
5. Maintain backward compatibility for simple user projects
|
||||
|
||||
## Pre-Work Checklist
|
||||
|
||||
Before starting, confirm you can:
|
||||
- [ ] Run the editor locally (`npm run dev`)
|
||||
- [ ] Build the viewer-react package
|
||||
- [ ] Create a test project with various nodes (Group, Text, Button, Repeater, etc.)
|
||||
- [ ] Deploy a test project
|
||||
|
||||
## Phase 1: React Bundle Replacement
|
||||
|
||||
### 1.1 Locate Current React Bundles
|
||||
|
||||
```bash
|
||||
# Find all React bundles in the runtime
|
||||
find packages/noodl-viewer-react -name "react*.js" -o -name "react*.min.js"
|
||||
```
|
||||
|
||||
Expected locations:
|
||||
- `packages/noodl-viewer-react/static/shared/react.production.min.js`
|
||||
- `packages/noodl-viewer-react/static/shared/react-dom.production.min.js`
|
||||
|
||||
### 1.2 Download React 19 Production Bundles
|
||||
|
||||
Get React 19 UMD production builds from:
|
||||
- https://unpkg.com/react@19/umd/react.production.min.js
|
||||
- https://unpkg.com/react-dom@19/umd/react-dom.production.min.js
|
||||
|
||||
```bash
|
||||
cd packages/noodl-viewer-react/static/shared
|
||||
|
||||
# Backup current files
|
||||
cp react.production.min.js react.production.min.js.backup
|
||||
cp react-dom.production.min.js react-dom.production.min.js.backup
|
||||
|
||||
# Download React 19
|
||||
curl -o react.production.min.js https://unpkg.com/react@19/umd/react.production.min.js
|
||||
curl -o react-dom.production.min.js https://unpkg.com/react-dom@19/umd/react-dom.production.min.js
|
||||
```
|
||||
|
||||
### 1.3 Update SSR Dependencies
|
||||
|
||||
File: `packages/noodl-viewer-react/static/ssr/package.json`
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"react": "^19.0.0",
|
||||
"react-dom": "^19.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Phase 2: Entry Point Migration
|
||||
|
||||
### 2.1 Locate Entry Point Render Implementation
|
||||
|
||||
Search for where `_viewerReact.render` and `_viewerReact.renderDeployed` are defined:
|
||||
|
||||
```bash
|
||||
grep -r "_viewerReact" packages/noodl-viewer-react/src --include="*.js" --include="*.ts"
|
||||
grep -r "ReactDOM.render" packages/noodl-viewer-react/src --include="*.js" --include="*.ts"
|
||||
```
|
||||
|
||||
### 2.2 Update to createRoot API
|
||||
|
||||
**Before (React 17):**
|
||||
```javascript
|
||||
import ReactDOM from 'react-dom';
|
||||
|
||||
window.Noodl._viewerReact = {
|
||||
render(rootElement, modules, options) {
|
||||
const App = createApp(modules, options);
|
||||
ReactDOM.render(<App />, rootElement);
|
||||
},
|
||||
|
||||
renderDeployed(rootElement, modules, projectData) {
|
||||
const App = createDeployedApp(modules, projectData);
|
||||
ReactDOM.render(<App />, rootElement);
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
**After (React 19):**
|
||||
```javascript
|
||||
import { createRoot } from 'react-dom/client';
|
||||
|
||||
// Store root reference for potential unmounting
|
||||
let currentRoot = null;
|
||||
|
||||
window.Noodl._viewerReact = {
|
||||
render(rootElement, modules, options) {
|
||||
const App = createApp(modules, options);
|
||||
currentRoot = createRoot(rootElement);
|
||||
currentRoot.render(<App />);
|
||||
},
|
||||
|
||||
renderDeployed(rootElement, modules, projectData) {
|
||||
const App = createDeployedApp(modules, projectData);
|
||||
currentRoot = createRoot(rootElement);
|
||||
currentRoot.render(<App />);
|
||||
},
|
||||
|
||||
unmount() {
|
||||
if (currentRoot) {
|
||||
currentRoot.unmount();
|
||||
currentRoot = null;
|
||||
}
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
### 2.3 Update SSR Rendering
|
||||
|
||||
File: `packages/noodl-viewer-react/static/ssr/index.js`
|
||||
|
||||
**Before:**
|
||||
```javascript
|
||||
const ReactDOMServer = require('react-dom/server');
|
||||
const output = ReactDOMServer.renderToString(ViewerComponent);
|
||||
```
|
||||
|
||||
**After (React 19):**
|
||||
```javascript
|
||||
// React 19 server APIs - check if this package structure changed
|
||||
const { renderToString } = require('react-dom/server');
|
||||
const output = renderToString(ViewerComponent);
|
||||
```
|
||||
|
||||
Note: React 19 server rendering APIs should be similar but verify the import paths.
|
||||
|
||||
## Phase 3: Built-in Node Audit
|
||||
|
||||
### 3.1 Search for Legacy Lifecycle Methods
|
||||
|
||||
These are REMOVED in React 19 (not just deprecated):
|
||||
|
||||
```bash
|
||||
cd packages/noodl-viewer-react
|
||||
|
||||
# Search for dangerous patterns
|
||||
grep -rn "componentWillMount" src/
|
||||
grep -rn "componentWillReceiveProps" src/
|
||||
grep -rn "componentWillUpdate" src/
|
||||
grep -rn "UNSAFE_componentWillMount" src/
|
||||
grep -rn "UNSAFE_componentWillReceiveProps" src/
|
||||
grep -rn "UNSAFE_componentWillUpdate" src/
|
||||
```
|
||||
|
||||
### 3.2 Search for Other Deprecated Patterns
|
||||
|
||||
```bash
|
||||
# String refs (removed)
|
||||
grep -rn "ref=\"" src/
|
||||
grep -rn "ref='" src/
|
||||
|
||||
# Legacy context (removed)
|
||||
grep -rn "contextTypes" src/
|
||||
grep -rn "childContextTypes" src/
|
||||
grep -rn "getChildContext" src/
|
||||
|
||||
# createFactory (removed)
|
||||
grep -rn "createFactory" src/
|
||||
|
||||
# findDOMNode (deprecated, may still work)
|
||||
grep -rn "findDOMNode" src/
|
||||
```
|
||||
|
||||
### 3.3 Fix Legacy Patterns
|
||||
|
||||
**componentWillMount → useEffect or componentDidMount:**
|
||||
```javascript
|
||||
// Before (class component)
|
||||
componentWillMount() {
|
||||
this.setupData();
|
||||
}
|
||||
|
||||
// After (class component)
|
||||
componentDidMount() {
|
||||
this.setupData();
|
||||
}
|
||||
|
||||
// Or convert to functional
|
||||
useEffect(() => {
|
||||
setupData();
|
||||
}, []);
|
||||
```
|
||||
|
||||
**componentWillReceiveProps → getDerivedStateFromProps or useEffect:**
|
||||
```javascript
|
||||
// Before
|
||||
componentWillReceiveProps(nextProps) {
|
||||
if (nextProps.value !== this.props.value) {
|
||||
this.setState({ derived: computeDerived(nextProps.value) });
|
||||
}
|
||||
}
|
||||
|
||||
// After (class component)
|
||||
static getDerivedStateFromProps(props, state) {
|
||||
if (props.value !== state.prevValue) {
|
||||
return {
|
||||
derived: computeDerived(props.value),
|
||||
prevValue: props.value
|
||||
};
|
||||
}
|
||||
return null;
|
||||
}
|
||||
|
||||
// Or functional with useEffect
|
||||
useEffect(() => {
|
||||
setDerived(computeDerived(value));
|
||||
}, [value]);
|
||||
```
|
||||
|
||||
**String refs → createRef or useRef:**
|
||||
```javascript
|
||||
// Before
|
||||
<input ref="myInput" />
|
||||
this.refs.myInput.focus();
|
||||
|
||||
// After (class)
|
||||
constructor() {
|
||||
this.myInputRef = React.createRef();
|
||||
}
|
||||
<input ref={this.myInputRef} />
|
||||
this.myInputRef.current.focus();
|
||||
|
||||
// After (functional)
|
||||
const myInputRef = useRef();
|
||||
<input ref={myInputRef} />
|
||||
myInputRef.current.focus();
|
||||
```
|
||||
|
||||
## Phase 4: createNodeFromReactComponent Wrapper
|
||||
|
||||
### 4.1 Locate the Wrapper Implementation
|
||||
|
||||
```bash
|
||||
grep -rn "createNodeFromReactComponent" packages/noodl-viewer-react/src --include="*.js" --include="*.ts"
|
||||
```
|
||||
|
||||
### 4.2 Audit the Wrapper
|
||||
|
||||
Check if the wrapper:
|
||||
1. Uses any legacy lifecycle methods internally
|
||||
2. Uses legacy context for passing data
|
||||
3. Uses findDOMNode
|
||||
|
||||
The wrapper likely manages:
|
||||
- `forceUpdate()` calls (should still work)
|
||||
- Ref handling (ensure using callback refs or createRef)
|
||||
- Style injection
|
||||
- Child management
|
||||
|
||||
### 4.3 Update if Necessary
|
||||
|
||||
If the wrapper uses class components internally, ensure they don't use deprecated lifecycles.
|
||||
|
||||
## Phase 5: Testing
|
||||
|
||||
### 5.1 Create Test Project
|
||||
|
||||
Create a Noodl project that uses:
|
||||
- [ ] Group nodes (basic container)
|
||||
- [ ] Text nodes
|
||||
- [ ] Button nodes with click handlers
|
||||
- [ ] Image nodes
|
||||
- [ ] Repeater (For Each) nodes
|
||||
- [ ] Navigation/Page Router
|
||||
- [ ] States and Variants
|
||||
- [ ] Custom JavaScript nodes (if the API supports it)
|
||||
|
||||
### 5.2 Test Scenarios
|
||||
|
||||
1. **Basic Rendering**
|
||||
- Open project in editor preview
|
||||
- Verify all nodes render correctly
|
||||
|
||||
2. **Interactions**
|
||||
- Click buttons, verify signals fire
|
||||
- Hover states work
|
||||
- Input fields accept text
|
||||
|
||||
3. **Dynamic Updates**
|
||||
- Repeater data changes reflect in UI
|
||||
- State changes trigger re-renders
|
||||
|
||||
4. **Navigation**
|
||||
- Page transitions work
|
||||
- URL routing works
|
||||
|
||||
5. **Deploy Test**
|
||||
- Export/deploy project
|
||||
- Open in browser
|
||||
- Verify everything works in production build
|
||||
|
||||
### 5.3 SSR Test (if applicable)
|
||||
|
||||
```bash
|
||||
cd packages/noodl-viewer-react/static/ssr
|
||||
npm install
|
||||
npm run build
|
||||
npm start
|
||||
# Visit http://localhost:3000 and verify server rendering works
|
||||
```
|
||||
|
||||
## Phase 6: Documentation & Migration Guide
|
||||
|
||||
### 6.1 Create Migration Guide for Users
|
||||
|
||||
File: `docs/REACT-19-MIGRATION.md`
|
||||
|
||||
```markdown
|
||||
# React 19 Runtime Migration Guide
|
||||
|
||||
## What Changed
|
||||
|
||||
OpenNoodl runtime now uses React 19. This affects deployed projects.
|
||||
|
||||
## Who Needs to Act
|
||||
|
||||
Most projects will work without changes. You may need updates if you have:
|
||||
- Custom JavaScript nodes using React class components
|
||||
- Custom modules using legacy React patterns
|
||||
|
||||
## Breaking Changes
|
||||
|
||||
These patterns NO LONGER WORK:
|
||||
|
||||
1. **componentWillMount** - Use componentDidMount instead
|
||||
2. **componentWillReceiveProps** - Use getDerivedStateFromProps or effects
|
||||
3. **componentWillUpdate** - Use getSnapshotBeforeUpdate
|
||||
4. **String refs** - Use createRef or useRef
|
||||
5. **Legacy context** - Use React.createContext
|
||||
|
||||
## How to Check Your Project
|
||||
|
||||
1. Open your project in the new OpenNoodl
|
||||
2. Check the console for warnings
|
||||
3. Test all interactive features
|
||||
4. If issues, review custom JavaScript code
|
||||

|
||||
## Verification Checklist
|
||||
|
||||
Before considering this task complete:
|
||||
|
||||
- [ ] React 19 bundles are in place
|
||||
- [ ] Entry point uses `createRoot()`
|
||||
- [ ] All built-in nodes render correctly
|
||||
- [ ] No console errors about deprecated APIs
|
||||
- [ ] Deploy builds work
|
||||
- [ ] SSR works (if used)
|
||||
- [ ] Documentation updated
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues are found:
|
||||
1. Restore backup React bundles
|
||||
2. Revert entry point changes
|
||||
3. Document what broke for future fix
|
||||
|
||||
Keep backups:
|
||||
```bash
|
||||
packages/noodl-viewer-react/static/shared/react.production.min.js.backup
|
||||
packages/noodl-viewer-react/static/shared/react-dom.production.min.js.backup
|
||||
```
|
||||
|
||||
## Files Modified Summary
|
||||
|
||||
| File | Change |
|
||||
|------|--------|
|
||||
| `static/shared/react.production.min.js` | Replace with React 19 |
|
||||
| `static/shared/react-dom.production.min.js` | Replace with React 19 |
|
||||
| `static/ssr/package.json` | Update React version |
|
||||
| `src/[viewer-entry].js` | Use createRoot API |
|
||||
| `src/nodes/*.js` | Fix any legacy patterns |
|
||||
|
||||
## Notes for Cline
|
||||
|
||||
1. **Confidence Check:** Before each major change, verify you understand what the code does
|
||||
2. **Small Steps:** Make one change, test, commit. Don't batch large changes.
|
||||
3. **Console is King:** Watch for React warnings in browser console
|
||||
4. **Backup First:** Always backup before replacing files
|
||||
5. **Ask if Unsure:** If you hit something unexpected, pause and analyze
|
||||
|
||||
## Expected Warnings You Can Ignore
|
||||
|
||||
React 19 may show these development-only warnings that are OK:
|
||||
- "React DevTools" messages
|
||||
- Strict Mode double-render warnings (expected behavior)
|
||||
|
||||
## Red Flags - Stop and Investigate
|
||||
|
||||
- "Invalid hook call" - Something is using hooks incorrectly
|
||||
- "Cannot read property of undefined" - Likely a ref issue
|
||||
- White screen with no errors - Check the console in DevTools
|
||||
- "Element type is invalid" - Component not exported correctly
