 Description

This Course in a Nutshell

If you don't know NestJs, it's like Angular but for the backend. With it, we can write our backend using the same concepts and object-oriented APIs that we already use to structure our Angular frontend: components, services, modules, pipes, etc.

NestJs is also quite similar to popular libraries that you might already be used to, such as, for example, the Spring library in the Java ecosystem, or ASP.NET MVC for the C# ecosystem.

Course Overview

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. We will be providing a complete CRUD example showing how to perform the most common REST data retrieval and data modification operations using NestJs.

No prior NestJs, MongoDB or Mongoose knowledge is assumed as we will explain everything from scratch. We will cover all the essential NestJs concepts such as Modules, Controllers and injectable services.

We will learn in detail how to validate business data using a decorator based approach (with decorators like @IsString(), @IsPhoneNumber(), etc.) by leveraging the built-in NestJs Validation pipe.

We will also implement using NestJs commonly needed backend security functionality such as User Authentication, RBAC (Role-Based Access Control) Authorization, error handling, and cover more advanced NestJs concepts such as Filters, Pipes, Guards, interceptors and middleware.
