What is NestJS?

The Web development technology tremendously change very quick. NestJS gain the popularity contraction in 2020.

I take some quote from official NestJS website:

Note

Nest (NestJS) is a framework for building efficient, scalable Node.js server-side applications. It uses progressive JavaScript, is built with and fully supports TypeScript (yet still enables developers to code in pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).

Nest itself is a framework with platform agnostic. It’s not depend to any architecture design, Not only to HTTP frameworks such as ExpressJS or Fastify but even agnostic across different types of applications.

In simple word, Nest teach you how to build your apps that can runs equally well across more than one specific design system architecture.

Note	NodeJS by design has a minimalistic setup, and developers are in charge of setting up everything they want to use for their application.

NestJS provides an out of the box the application architecture that allows developer and to create highly testable, scalable, loosely coupled, and easily maintainable application. You can read more in chapter-1

How good is NestJS?

As a software - engineer it’s so painful to create a documentation for your software product. With Nest it easier to write clean and clear documentation related to API documentation. You can read more in chapter-7.

That is one of the reasons why I wanted to learn Nestjs deeply and fundamentally to find out what could be implemented with Nest.

You want to know more about the advantages with Nest. Check below, why I write this course.

Why You Write all This?

I wrote all this course with the samples in every chapter and project, cause I know someday in next years I’ve to repeat what I read. If I repeat myself by watching video over and over again without writing it, I’m only renting the knowledge, not owning it.

This course is have 9 - chapter.

1.	Getting Started with Nest
2.	Creating REST API Application
3.	Add PostgreSQL with Type - ORM
4.	Dependency Injection
5.	Application Configuration
6.	Building Blocks by Example
7.	Generating OpenAPI Specification
8.	Testing
9.	MongoDB with Mongoose
