How can I use TypeORM for seeding my database?

How can I use TypeORM for seeding my database?

You can use TypeORM's built-in seeding capabilities by creating a seeder class and using the createQueryBuilder method.

Can you show me a simple example of a seeder?

Sure! Here's a basic example:

import { Factory, times } from 'typeorm-seeding';
import { Connection } from 'typeorm';
import { User } from '../entities/User';

export default class CreateUsers implements Seeder {
  public async run(factory: Factory, connection: Connection): Promise<void> {
    await factory(User) .createMany(10);
  }
}

What if I want to seed different types of data?

You can create multiple seeder classes for different entities and run them in sequence or parallel as needed.

Is there a way to reset the database before seeding?

Yes, you can use TypeORM's synchronize option or run a migration to reset your database before seeding.
