Raven Nest is a modern backend service built with NestJS, TypeORM, and PostgreSQL, designed to provide a scalable, modular, and secure foundation for Raven’s ecosystem.
It implements clean architecture principles and includes built-in authentication, validation, and monitoring.

• NestJS + TypeORM: Modular and dependency-injected structure for maintainable services.
• Authentication & Authorization: JWT-based login with Passport integration.
• Validation: Global ValidationPipe for DTOs with strict input sanitization.
• Security: Helmet middleware and rate limiting (Throttler) enabled by default.
• Health Monitoring: /health and HEAD /health endpoints for uptime checks.
• API Documentation: Integrated Swagger UI with JWT auto-authorization.
• CORS & Environment Config: Dynamic configuration for multiple origins and deployment stages.

Create a .env file in the project root with the following configuration:

# Server
PORT=4000
CORS_ORIGINS=http://localhost:3000

# PostgreSQL
PGHOST=localhost
PGPORT=5432
PGDATABASE=raven_nest
PGUSER=postgres
PGPASSWORD=postgres

# JWT
JWT_SECRET=change-me
JWT_EXPIRES=1h

npm install

npm run start:dev

npm run build
npm run start:prod

Once the server is running, Swagger UI is available at:

http://localhost:4000/docs

• Persistent JWT authorization (keeps token after page refresh)
• Auto-login script integrated to read token from localStorage after /auth/login
• Bearer scheme automatically configured for all secured routes

The application includes essential security middleware by default:

• helmet() → sets HTTP headers to secure Express apps
• ValidationPipe → cleans and validates all incoming payloads
• ThrottlerModule → rate-limits requests per IP
• CORS → controlled through environment variables

Endpoints available for monitoring and uptime verification:

• Follow NestJS module-first structure
• Maintain DTOs for every endpoint
• Ensure Swagger decorators for public APIs
• Run ESLint and Prettier before pushing any changes
• Prefer TypeScript strict mode and explicit typing
