# Frontend Dependencies Analysis - November 2025

## Current State
- React: ^18.3.1 (April 2024)
- Vite: ^5.1.0 (January 2024)
- TypeScript: ^5.3.3 (November 2023)
- Terser: ^5.31.0 (just added - GOOD)
- @vitejs/plugin-react: ^4.3.0
- @types packages: vary from 18.3.0 to 20.11.0

## Latest Available Versions

### React Ecosystem
- **React Latest**: 19.2.0 (October 2025) - mature, 1+ year stable
- **React 18 Latest**: 18.3.1 (April 2024) - still maintained, zero CVEs
- **React DOM Latest**: 19.2.0 or 18.3.1
- **@types/react Latest**: 18.3.3 (for React 18)
- **@types/react-dom Latest**: 18.3.0 (for React 18)

### Build Tools
- **Vite Latest**: 6.3+ (November 2025) - production-ready since Dec 2024
- **Vite 5 Latest**: 5.4.1 (still maintained)
- **@vitejs/plugin-react Latest**: 4.3.x (works with both Vite 5 & 6)
- **TypeScript Latest**: 5.9.x (December 2024)

### Code Quality
- **Terser Latest**: 5.31.0+ (current, good)
- **@types/node Latest**: 20.12.x (safe patch bump from 20.11.0)

## Codebase Compatibility Assessment

### React 19 Readiness: ✅ READY
The codebase is **already React 19 compatible**:
- Using `React.createRoot()` (modern API) ✓
- Using modern hooks (useState, useEffect, useContext) ✓
- No PropTypes (using TypeScript instead) ✓
- No string refs or legacy APIs ✓
- No findDOMNode usage ✓
- Proper Error Boundary implementation ✓
- Using React.StrictMode ✓

### Vite 6 Readiness: ✅ READY
Simple SPA configuration is backward compatible:
- Minimal vite.config.ts (no advanced features) ✓
- Using @vitejs/plugin-react (stable in both v5 & v6) ✓
- No SSR configuration ✓
- Standard TypeScript config ✓

## MVP Deployment Recommendation

### TIER 1: IMMEDIATE UPGRADES (Safe, Zero Risk)
```json
{
  "typescript": "^5.9.3",
  "@types/node": "^20.12.0",
  "@types/react": "^18.3.3",
  "@types/react-dom": "^18.3.0",
  "terser": "^5.31.0"
}
```
**Rationale**: All safe minor/patch updates, no breaking changes, better TypeScript strict mode compliance

### TIER 2: OPTIONAL (Very Low Risk)
```json
{
  "vite": "^5.4.1"
}
```
**Rationale**: Stay on Vite 5 (fully maintained), get latest v5 features without major refactor

### TIER 3: POST-MVP (After Validation)
```json
{
  "react": "^19.2.0",
  "react-dom": "^19.2.0",
  "vite": "^6.3.0"
}
```
**Rationale**: After MVP validation, upgrade to latest stable versions with new capabilities

## Breaking Changes Analysis

### React 18 → 19
**If upgrading later:**
- Removed: ReactDOM.render (we use createRoot ✓)
- Removed: PropTypes (we use TypeScript ✓)
- Removed: Legacy Context API (not used ✓)
- Changed: Error handling via window.reportError
- No changes needed to current codebase

### Vite 5 → 6
**If upgrading later:**
- Environment API changes (internal only, backward compatible)
- Default browser target updated (baseline-widely-available)
- Removed: Sass legacy API (not used)
- Node.js requirement: 20.19+ / 22.12+ (already compatible)
- Config remains unchanged for simple SPAs

### TypeScript 5.3 → 5.9
- **No breaking changes** in our strict mode config
- Better type inference
- Enhanced strict mode features
- All updates are safe

## Security Status
- React 18.3.1: ✓ No known CVEs
- React 19.2.0: ✓ No known CVEs
- Vite 5.4.1: ✓ No known CVEs
- Vite 6.3+: ✓ No known CVEs
- TypeScript 5.9: ✓ No known CVEs
- Terser 5.31.0: ✓ No known CVEs

## Vercel Deployment Readiness
- ✓ Vite officially supported on Vercel
- ✓ React + TypeScript recommended stack
- ✓ Current vite.config.ts compatible
- ✓ tsconfig.json properly configured
- ✓ Node.js support: 18+ (Vercel provides)

## Recommended Action Plan

1. **Week 1 (MVP)**: Update TIER 1 packages only
   - Run `yarn upgrade typescript @types/node @types/react @types/react-dom`
   - Verify build: `yarn build`
   - Deploy to Vercel

2. **Week 2-4 (Post-MVP)**: Evaluate Vite upgrade
   - Test Vite 5.4.1
   - Profile build times
   - Monitor user feedback

3. **Month 2 (Post-MVP Validation)**: Plan major upgrades
   - React 18 → 19 migration (if benefits justify)
   - Vite 5 → 6 migration (for new tooling features)
   - Systematic testing and rollback plan

## Package.json Recommendation (MVP Ready)

```json
{
  "name": "kinemotion-frontend",
  "private": true,
  "version": "0.1.0",
  "type": "module",
  "packageManager": "yarn@4.12.0",
  "scripts": {
    "dev": "vite",
    "build": "tsc && vite build",
    "preview": "vite preview",
    "type-check": "tsc --noEmit"
  },
  "dependencies": {
    "react": "^18.3.1",
    "react-dom": "^18.3.1"
  },
  "devDependencies": {
    "@types/node": "^20.12.0",
    "@types/react": "^18.3.3",
    "@types/react-dom": "^18.3.0",
    "@vitejs/plugin-react": "^4.3.0",
    "terser": "^5.31.0",
    "typescript": "^5.9.3",
    "vite": "^5.4.1"
  }
}
```

## Next Steps
1. Update package.json with TIER 1 changes
2. Run `yarn install`
3. Run `yarn build` and `yarn type-check`
4. Deploy to Vercel
5. Schedule post-MVP evaluation for TIER 2 & 3 upgrades
