Request/Response objects, headers, cookies. Streaming responses. 🛠 Hands-On : Create app/api/posts/route.ts (GET all, POST new). Create app/api/posts/[id]/route.ts (GET one, PUT, DELETE). Test with Postman/Thunder Client. Add proper error handling and status codes. 🧪 Mini-Project : "REST API for Posts" — A complete REST API for blog posts with pagination (?page=1&limit=10), search (?q=nextjs), and sorting.
