# Building Scalable APIs with Node.js
Learn best practices for building production-ready APIs with Node.js, Express, and PostgreSQL.
## Architecture Principles
When building scalable APIs, consider these key principles:
1. **Separation of Concerns**: Keep your routes, controllers, and services separate
2. **Error Handling**: Implement consistent error handling across your API
3. **Authentication**: Use JWT tokens for stateless authentication
4. **Rate Limiting**: Protect your API from abuse
5. **Database Optimization**: Use connection pooling and proper indexing
## Implementation Example
```typescript
import express from 'express';
import { PrismaClient } from '@prisma/client';
const app = express();
const prisma = new PrismaClient();
app.get('/api/users', async (req, res) => {
const users = await prisma.user.findMany();
res.json(users);
});
```
## Conclusion
Building scalable APIs requires careful planning and adherence to best practices. Focus on clean architecture, proper error handling, and performance optimization.
