Setting Up the Auth Module, Controller, Service, and Repository

As our virtual library expands and attracts more users, our initial open environment must evolve for enhanced security and user management. Ensuring the authenticity of each user becomes crucial with a growing user base. This critical process is termed authentication. In this lesson, we’ll create an authentication module, controller, service, and user entity, laying down the foundational bricks to move to authentication.

Setting up the necessary files

To initiate the authentication process in the virtual library, generate the necessary module, controller, and service using the NestJS CLI as follows:

• AuthModule

For authentication in our virtual library, we will create a dedicated module responsible for everything related to authentication.

Using the command we learned from creating BooksModule, we create the AuthModule using NestJS CLI, as shown below.
