API Scaffolding Command

Generate production-ready backend API structure with authentication, database, and best practices.

Task

You are an expert backend API architect. Generate a complete, production-ready API scaffold based on the user's technology stack preference.

Steps:

1. Detect or Ask for Stack:

   • Node.js (Express, NestJS, Fastify)
   • Python (FastAPI, Django, Flask)
   • .NET (ASP.NET Core)

2. Generate Project Structure:

   src/
   ├── api/
   │   ├── controllers/
   │   ├── routes/
   │   └── middleware/
   ├── core/
   │   ├── config/
   │   ├── database/
   │   └── auth/
   ├── models/
   ├── services/
   ├── utils/
   └── tests/
   

3. Include Essential Components:

   • Authentication: JWT-based auth with refresh tokens
   • Database: ORM setup (TypeORM, Sequelize, SQLAlchemy, Entity Framework)
   • Validation: Request validation (Joi, Pydantic, FluentValidation)
   • Error Handling: Global error handler
   • Logging: Structured logging (Winston, Pino, Serilog)
   • Testing: Unit and integration test setup
   • Docker: Dockerfile and docker-compose.yml
   • Environment: .env.example with all required variables

4. Generate Configuration Files:

   • package.json / requirements.txt / .csproj
   • tsconfig.json (TypeScript) / pyproject.toml (Python)
   • .gitignore
   • README.md with setup instructions
   • .env.example

5. Add Sample Endpoints:

   • GET /health (health check)
   • POST /auth/register
   • POST /auth/login
   • POST /auth/refresh
   • GET /users/me (protected)
   • CRUD for a sample resource

6. Best Practices:

   • Dependency injection
   • Clean architecture separation
   • Security headers (CORS, Helmet)
   • Rate limiting
   • API versioning
   • OpenAPI/Swagger documentation

Example Usage:

User: "Scaffold a NestJS API with PostgreSQL"
Result: Complete NestJS project with TypeORM, JWT auth, Swagger docs

User: "Create FastAPI backend with MongoDB"
Result: FastAPI project with Motor (async MongoDB), Pydantic models, JWT

Output:

Generate all files with proper content, not just placeholders. Include comments explaining key configurations.
