Take your Node backend to the next level with NestJS

NestJS is a backend framework designed for building scalable applications, providing an abstraction over HTTP server libraries like Express and Fastify while enforcing a specific architecture reminiscent of Angular. It utilizes modules, services, and controllers to ensure applications are scalable, testable, and maintainable, setting it apart from other frameworks like Express or Koa, which offer more flexibility but less architectural guidance. With its strong emphasis on dependency injection, NestJS allows for loosely coupled and easily testable code, and its CLI facilitates productivity by generating boilerplate code and basic tests. The framework supports REST and GraphQL APIs and integrates well with libraries like Swagger for documentation and typeorm, passport, and mongoose for database and authentication needs. Despite some limitations, the growing community around NestJS and its adaptability to modern trends make it a popular choice for developers seeking a structured yet flexible backend framework.
