Next.js App Router route handlers are just functions — GET, POST, whatever you export. That's the whole appeal: no framework, no ceremony, straight to the Web Request/Response APIs. It's also exactly where the pain starts once an API grows past two or three endpoints. This post builds the same small Post resource twice — once with plain route handlers, once with nextjs-nestapi — and compares what actually changed.

Wiring up app.ts, the catch-all route, and tsconfig.json's decorator flags by hand is only a few minutes of work — but it's a few minutes you'll repeat on every new project or feature. The nextjs-nestapi CLI does it for you.

If you're already annotating controllers with @Controller, @Get/@Post, and @Body(DtoClass), you've already written most of what an OpenAPI document needs. This post shows how nextjs-nestapi turns that into a live spec and a Swagger UI, with no separate documentation step to keep in sync.
