# openapi-to-application-nodejs-nestjs

Builds a NestJS application from an OpenAPI spec: project scaffolding, controllers, services. Useful when the API contract exists but the code does not.

## What it does

The plugin adds a slash command `/openapi-to-application-nodejs-nestjs:openapi-to-application-code` and an agent named `openapi-to-application` to GitHub Copilot. The command generates a whole application from your spec; the agent helps with individual pieces of that generation.

It produces project structure, controllers and services in TypeScript. The description mentions TypeScript best practices and enterprise patterns, so the output targets a working service rather than a demo. Have your OpenAPI specification ready first — the command has nothing to read without it.

Worth installing if you keep your API contract in OpenAPI and would rather not hand-port it into NestJS. No contract, or a different framework, and there is little here for you.

## Install

### GitHub Copilot (native platform)

**Command from the source**
```bash
copilot plugin install openapi-to-application-nodejs-nestjs@awesome-copilot
```

## When to use it
- scaffold a NestJS project from an existing OpenAPI spec
- generate controllers and services for the endpoints you described
- move an API contract into TypeScript without rewriting it by hand
- get an app structure that follows enterprise patterns

## Example prompts
- /openapi-to-application-nodejs-nestjs:openapi-to-application-code — generate the app from `openapi.yaml`
- Read the spec in `api/openapi.json` and build a NestJS project with controllers and services
- Help me extend the generated service to match my spec
