route-handlers

What problem does it solve?

Route handlers in Next.js can be verbose and repetitive when building API endpoints with the App Router. This guide helps developers design clear, scalable API routes that support multiple HTTP methods, dynamic segments, streaming, and SSE.

Core Features & Use Cases

• Multi-method endpoint patterns: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS.
• Dynamic routing and context extraction for parameterized APIs.
• Streaming responses and Server-Sent Events (SSE) for real-time updates and large payloads.
• Practical examples and patterns to accelerate production-grade API development.

Quick Start

Create a Next.js API route at /api/users supporting GET and POST and demonstrating streaming responses.
