User entity

We shall now create the User entity, defining its class and attributes.

Now that we have our project configured, we can start marching towards our main objective - developing our shop backend system. Let's create the User resource. We shall do so inside the domain folder, to group domain's entities together.

nest g res domain/users

Choose the following options

• Transport Layer - REST API

• CRUD entry points - Yes

The nest resource includes:

• The entity class

• DTOs for creating and updating an entity

• A module to encapsulate this context

• A controller with the basic routes for this entity

• A service with the logic for the routes

• Automated tests

But right now, we should focus on the entity class. So let's go to src/domain/users/entities/user.entity.

When the file extension is not shown, you can consider that it is a TypeScript (.ts) file.

Inside the class, we will insert the entity's attributes.

id: number;
name: string;
email: string;
phone: string;
password: string;

After that, we should copy all these fields (except id) and paste them in the create-user.dto file located in the dto folder inside users. This process will be necessary for the next lesson.

Some tips:

• Prefixing DTO fields with readonly is a good practice

• The ALT + CLICK allows for multiple cursors, and thus prefixing all the fields at once
