Can you learn NestJS completely online?
If you already have ninja skills in JavaScript then I guess you’ll find NestJS quite a breeze to learn. But again you’d ask yourself why to learn NestJS for example if you are already a master of the MERN stack.
Well, to begin with, I would say it will dramatically increase your productivity as a full-stack well developer today.
By taking the best NestJS courses online, you’ll skip the unnecessary time wasted with traditional programming courses, not to mention that some of the traditional courses don’t even teach NestJS.
Finally, you’ll be able to use NestJS to write scalable code, that is easily testable while making your applications decoupled. In addition to that, you’ll be able to use NodeJS with databases like MongoDB and MySQL.
In this article, we are going to look at the best NestJS courses and certifications online to get you started with this JavaScript framework.
Let’s get started.
NestJS leverages the incredible popularity and robustness of JavaScript as a language and Node.js as a technology. It is inspired by common libraries and frameworks such as Angular, React and Vue which improve developer productivity and experience.
It provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled and easily maintainable applications.
In this NestJS course online the instructor will guide you through the process of planning, developing and deploying a fully-featured back-end application, based on his experience developing and maintaining systems that support dozens of millions of concurrent users at scale.
It is one of the best NestJS tutorials on Udemy for learning dozens of nest-specific modules that help you easily integrate with common technologies and concepts such as TypeORM, Mongoose, GraphQL, Logging, Validation, Caching, Websockets and much more.

This course will help you master Nest. By the time you complete this NestJS course online, you will have the confidence to build any app you can imagine.
Throughout this course you will build a series of apps with growing complexity, while using as few libraries and tools as possible. Instead, you will write many custom systems to better understand how every piece of Nest works together.
Each application you build includes discussion on data modeling and persistence. You’ll first save records in a simple file-based data store (built from scratch) and eventually work your way up to saving data in a production-grade Postgres instance.
It is actually one of the best ways to learn NestJS online today.
This course follows Nest’s testing recommendations, and you will write both integration and unit tests to ensure your project is working as expected.
In this course, you are going to learn from scratch how to design and develop a NestJs backend that will take the form of a REST API that queries a MongoDB database using the Mongoose ODM (Object Document Mapping) library.
So you’ll get to build a complete CRUD example showing how to perform the most common REST data retrieval and data modification operations using NestJs.
It is one of the best NestJS tutorials online because no prior NestJs, MongoDB or Mongoose knowledge is assumed as the instructor explains everything from scratch.

NestJS is the best way to enter the world of JavaScript/TypeScript Node.js programming. It’s an easy-to-learn and powerful framework.
Once you take this NestJS course will go from the very basics into more advanced concepts like routing and controllers, databases including TypeORM (Repository, Query Builder, Relations), as well as using Docker in your local development workflow.
You also get full source code for all the projects included and is available on GitHub at all times. Including a separate branch for every lecture with code changes.
It is a great resource for learning NestJS because the instructor makes sure everything is as clear and simple as possible, so there are a lot of diagrams and visual aids included (and available for download too).
Finally, there are also some lessons on authentication, including Passport.js, Bcrypt, as well as JSON Web Tokens (JWT) generation and usage.
