  • A basic understanding of JavaScript on NodeJS
  • Basic knowledge of TypeScript is recommended, but not required

What will you learn in this course?

  • Design and develop RESTful web services
  • Using Nest CLI efficiently
  • Create CRUD. operations
  • Modules, controllers and injectables
  • Filters and Pipes
  • Validation
  • DTO or Data Transfer Objects
  • Asynchronous operations using async/await
  • Persisting data in MongoDB collections
  • Industry standard best practices
  • Connecting to MongoDB cloud based server
  • Deploying our application to Heroku server

Who this course for?

  • Angular developers who want to apply their Angular/Typescript skills on the back end to create RESTful web services
  • Intermediate JavaScript developers who want to dive into back-end development
  • Any developers willing to apply TypeScript on the back-end
  • Developers eager to learn how to develop performant, secure and production-ready REST APIs following best practices
  • Developers who want to learn how to deploy their application to the cloud (Amazon Web Services)
  • Developers who want to follow building a practical, real-world application from zero to production


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).

Under the hood, Nest makes use of robust HTTP Server frameworks like Express (the default) and optionally can be configured to use Fastify as well!

Nest provides a level of abstraction above these common Node.js frameworks (Express/Fastify), but also exposes their APIs directly to the developer. This allows developers the freedom to use the myriad of third-party modules which are available for the underlying platform.

In recent years, thanks to Node.js, JavaScript has become the “lingua franca” of the web for both front and backend applications. This has given rise to awesome projects like Angular, React and Vue, which improve developer productivity and enable the creation of fast, testable, and extensible frontend applications. However, while plenty of superb libraries, helpers, and tools exist for Node (and server-side JavaScript), none of them effectively solve the main problem of - Architecture.

Nest provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled, and easily maintainable applications. The architecture is heavily inspired by Angular.

In this course I am going to guide you through the process of planning, developing and deploying a fully-featured RESTful web service using TypeScript+NestJS on Node platform.
