Generating Controllers, Services, and Module From the CLI
Learn how to use the NestJS CLI to generate boilerplate code.
Now that we have a fundamental understanding of the NestJS CLI, we’ll explore how to use it to generate key building blocks of a NestJS application, including modules, controllers, and services. We’ll see how these commands create files quickly, helping us avoid the often tedious process of manual file creation.
Generating a module
Suppose we build a user management system that handles user registrations, logins, and other user-related operations. We’ll need to create a dedicated module to encapsulate all these functionalities, a controller to handle HTTP requests, and a service for business logic. Let’s start with a module.
For example, to generate the users module from NestJS CLI, run the following command:
nest g mo users
This command will generate a new users.module.ts file within the src/users folder.
src/
├── app.controller.ts
├── app.module.ts
├── app.service.ts
└── users/
└── users.module.ts
Generating controllers
To generate the users controllers, run the following command:
nest g controller users
