Design, build, secure, and document REST APIs using Next.js Route Handlers — with AI assistance at every step from architecture to testing.
Before
Create a new API resource in your Next.js project: pick an entity (posts, products, tasks) and build the full CRUD — `route.ts` for the collection (GET list, POST create) and `[id]/route.ts` for individual resources (GET one, PATCH update, DELETE). Add Zod validation on the POST endpoint. Test with `curl` or a tool like Postman.
After
Good API design is predictable: resources are nouns, HTTP methods are verbs, status codes tell the story. Next.js Route Handlers give you a clean way to build this with the standard Web Request/Response API — no Express needed.
Tip
Be specific about what you need. The more context you provide, the better the result.
