What Is NestJS?

NestJS is a Node.js framework for creating fast, testable, scalable, loosely coupled server-side applications that use TypeScript. It takes advantage of powerful HTTP server frameworks such as Express or Fastify. Nest adds a layer of abstraction to Node.js frameworks and exposes their APIs to developers. It supports database management systems like PostgreSQL and MySQL. NestJS also offers dependency injections Websockets and APIGetaways.
