If you want to build a powerful API in the modern backend framework NestJs or if you want to learn how to unit test API then welcome to this Ultimate NestJs course.

NestJs is a Node.js framework for building efficient, reliable, and scalable Node.js server–side applications. NestJs is a complete framework that will help us to perform everything whether it is authentication or testing a complete API, NestJs provides us everything that we want. The architecture of NestJs is unmatchable.

Throughout this course, we will use TypeScript that will level up our development. Typescript will help us to write neat and clean code. We will be able to find our errors and bug right on the spot.

NestJs provides us a lot of flexibility by providing a lot of modules, when it comes to testing, NestJs provides us with Testing Module that makes Unit testing fun. Connecting to a database whether it is Relational (SQL, POSTGRES, etc) or NoSQL (MongoDB) is just fun and can be done in one line of code.

Really NestJs has made life a lot easier when it comes to building backend applications. The API built with this amazing framework is highly testable, scalable, loosely coupled, and easily maintainable applications.
