|
||
|
|
- Building Next.js 14+ applications with App Router
|
||
|
|
- Implementing server components and server actions
|
||
|
|
- Setting up data fetching, caching, and revalidation
|
||
|
|
- Optimizing performance (images, fonts, bundles)
|
||
|
|
- Implementing SEO with Metadata API
|

1. **Architecture planning** - Define app structure, routes, layouts, rendering strategy
|
||
|
|
2. **Implement routing** - Create App Router structure with layouts, templates, loading states
|
||
|
|
3. **Data layer** - Setup server components, data fetching, caching, revalidation
|
||
|
|
4. **Optimize** - Images, fonts, bundles, streaming, edge runtime

|
||
|
|

|
## Constraints
|
||
|
|
|
||
|
|
### MUST DO
|
||
|
|
- Use App Router (NOT Pages Router)
|
||
|
|
- Use TypeScript with strict mode
|
||
|
|
- Use Server Components by default
|
||
|
|
- Mark Client Components with 'use client'
|
||
|
|
- Use native fetch with caching options
|
||
|
|
- Use Metadata API for SEO
|
||
|
|
- Optimize images with next/image
|
||
|
|
- Use proper loading and error boundaries
|
||
|
|
- Target Core Web Vitals > 90
|
||
|
|
|
||
|
|
### MUST NOT DO
|
||
|
|
- Use Pages Router (pages/ directory)
|
||
|
|
- Make all components client components
|
||
|
|
- Fetch data in client components unnecessarily
|
||
|
|
- Skip image optimization
|
||
|
|
- Hardcode metadata in components
|
||
|
|
- Use external state managers without need
|
||
|
|
- Skip error boundaries
|
||
|
|
- Deploy without build optimization
|
||
|
|
|
||
|
|
## Output Templates
|
||
|
|
|
||
|
|
When implementing Next.js features, provide:
|
||
|
|
1. App structure (route organization)
|
||
|
|
2. Layout/page components with proper data fetching
|
||
|
|
3. Server actions if mutations needed
|
||
|
|
4. Configuration (next.config.js, TypeScript)
|
||
|
|
5. Brief explanation of rendering strategy
|
||
|
|
|
||
