# Modern Full-Stack Development with Next.js 15 and TypeScript
Next.js 15 represents a significant evolution in React development, introducing powerful features like Server Components, the App Router, and improved performance optimizations. In this guide, I'll share best practices from building production applications.
## Why Next.js 15?
Next.js 15 offers several compelling features:
- **React Server Components**: Reduce client-side JavaScript
- **App Router**: More intuitive file-based routing
- **Streaming**: Progressive page rendering
- **Turbopack**: Faster development builds
- **Server Actions**: Simplified server mutations
## Project Structure
A well-organized project structure is crucial for maintainability. Here's my recommended approach:
```
src/
├── app/ # App router pages
├── components/ # Reusable components
│ ├── ui/ # Base UI components
│ └── layout/ # Layout components
├── lib/ # Utilities and helpers
├── hooks/ # Custom React hooks
└── types/ # TypeScript types
```
## TypeScript Best Practices
### Strict Mode
Always enable strict mode in tsconfig.json for maximum type safety.
### Type-Safe API Routes
Use Zod for runtime validation and type inference. This ensures your API routes are both type-safe and validated at runtime.
## Server Components vs Client Components
Understanding when to use each is crucial:
**Server Components** (default):
- Data fetching
- Heavy computations
- Sensitive operations
- SEO content
**Client Components**:
- Interactivity (onClick, onChange)
- Browser APIs
- State management
- Real-time updates
## Database Integration with Prisma
Prisma provides excellent TypeScript integration:
1. Type-safe database queries
2. Auto-generated types from schema
3. Easy migrations
4. Great developer experience
## Performance Optimization
### Image Optimization
Use the Next.js Image component for automatic optimization, lazy loading, and responsive images.
### Code Splitting
Next.js automatically splits code, but you can optimize further with dynamic imports for heavy components.
## Deployment Considerations
For production deployment:
1. Enable caching strategies
2. Set up proper environment variables
3. Configure CDN for static assets
4. Monitor performance metrics
## Conclusion
Next.js 15 with TypeScript provides an excellent foundation for building modern web applications. The combination of type safety, performance optimizations, and developer experience makes it my go-to stack for full-stack development.
