How can I configure TypeORM for advanced use cases?

You can configure TypeORM for advanced use cases by utilizing features like custom repositories, migrations, and query builders.

What are custom repositories and how do I create one?

Custom repositories allow you to define your own methods for data access. You can create one by extending the Repository class.

Can you show me an example of a custom repository?

Sure! Here's a simple example:

import { EntityRepository, Repository } from 'typeorm';
import { User } from './User';

@EntityRepository(User)
export class UserRepository extends Repository<User> {
    async findByEmail(email: string) {
        return this.findOne({ where: { email } });
    }
}

What about migrations? How do I set them up?

You can set up migrations in TypeORM by using the CLI. Run typeorm migration:create -n MigrationName to create a new migration.
