nestjs - What does putting a parameter in @Entity() do?

Question

@Entity('user')
export class UserEntity {  
    @PrimaryGeneratedColumn('uuid') id: string;  
    @Column({ 
        type: 'varchar', 
        nullable: false, 
        unique: true 
    }) 
    username: string;
    @Column({ 
        type: 'varchar', 
        nullable: false 
    }) 
    password: string;  
}

What purpose does the 'user' in @Entity() have? In the controller, we put parameters inside the @Get() or similar methods to specify route...but no such thing happens in the Entity file.

This is where I got the code from: https://www.codemag.com/Article/2001081/Nest.js-Step-by-Step-Part-3-Users-and-Authentication

Answer 1

This parameter overrides the default table name used for that entity. In your case the table would be called "user". If you didn't pass this parameter the table name would have been "userEntity" or "user_entity", I'm not quite sure.
