Description

NestJS is a Node.js back-end development framework built upon Express, leveraging the power of TypeScript.

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.

Even considering the amount of superb libraries, helpers and tools that exist for server-side Node.js, none of them effectively solve the main problem - the architecture of an application.

NestJS provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled and easily maintainable applications.

Recently, the NestJS framework is gaining extreme popularity due to its incredible features;

Leverages TypeScript - strongly typed language which is a super-set of JavaScript
Simple to use, easy to learn and easy to master
Powerful Command Line Interface (CLI) tool that boosts productivity and ease of development
Detailed, well-maintained documentation

Active codebase development and maintenance
Open-source (MIT license)
Supports dozens 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
Easy of unit-testing applications
Made for Monoliths and Micro-services (entire section in the documentation regarding the Microservice type of a NestJS application, as well as techniques and recipes).
In this course I am going to guide you through the process of planning, developing and deploying a fully-featured back-end application, based on my experience developing and maintaining systems that support dozens of millions of concurrent users at scale.
