Example project

A complete, runnable example — routing, DTO validation, and the OpenAPI/Swagger setup — lives in example/ in the main repository: a real create-next-app project with nextjs-nestapi wired in.

git clone https://github.com/DeveloperRejaul/nextjs-nestapi.git
cd nextjs-nestapi/example
npm install
npm run dev

Then open http://localhost:3000 for links to the API routes, and /api-docs for the Swagger UI.

What it demonstrates​

  • A HelloController with @Get, @Get("/:id"), and @Post + @Body(CreateHelloDto)
  • DTO validation failures returning a structured error response
  • @ApiTags/@ApiOperation/@ApiResponse annotations
  • /api/openapi.json and /api-docs wired via generateOpenApiDocument() and createSwaggerUiHandler()
