Why Nestjs is so great

• TypeScript

  Nestjs is a TypeScript based Node.js framework. This means that you can use static-type to write your code.

• Model view controller pattern

  Since ExpressJS doesn't follow MVC, there's no proper structure which makes the application inefficient and less optimized. NestJS becomes a better choice for developers as it is clearly based on an architecture with components like modules, controllers, and providers.

• Microservices

  Looking at the capabilities of an application, a microservice-based architecture has gained popularity in recent years. NestJS is a Node. JS framework based on ExpressJS, but it's more than that. In fact, NestJS gives you everything you need to create microservices easily.

• Commmand line interface

  Nest have a powerful command line tool Interface (CLI) to boost productivity and ease of development

  For example you want to create a controller file

    nest generate controller <controllerName>
  

  Just write this command in terminal
