How do I design entities in TypeORM?

To design entities in TypeORM, you start by defining a class that represents your entity. Each class property corresponds to a database column.

Can you show me an example of an entity?

Sure! Here's a simple example:

import { Entity, PrimaryGeneratedColumn, Column } from 'typeorm';

@Entity()
export class User {
    @PrimaryGeneratedColumn()
    id: number;

    @Column()
    name: string;

    @Column()
    email: string;
}

What decorators are available in TypeORM?

TypeORM provides several decorators like @Entity, @Column, @PrimaryGeneratedColumn, @OneToMany, and @ManyToOne to define relationships and properties.

How do I set up relationships between entities?

You can use decorators like @OneToMany and @ManyToOne to establish relationships. For example:

@OneToMany(() => Post, post => post.user)
posts: Post[];
