Build modern and scalable Node.js Web Applications with Nest
summary
Shows how Nest.js boots a working backend: use nest new and run npm run start to get a live server, scaffold controllers + services and use decorators to route requests. Demonstrates REST, GraphQL and WebSocket support, automatic content-type handling, RxJS observables auto-subscription, and database wiring via TypeORM with SQLite so entities create tables and CRUD works through Postman. Includes CLI generators, DTO validation patterns, and a small demo that creates a full API with few files.
