Steps to seed a default admin user

Now, let’s create our first migration

typeorm migration:create -n CreateAdminUser

Then, we are going to modifie the generated file:

import { MigrationInterface, QueryRunner, getRepository } from "typeorm";
import { User } from "../entity/User";

export class CreateAdminUser1547919837483 implements MigrationInterface {
public async up(queryRunner: QueryRunner): Promise<any> {
    let user = new User();
    user.username = "admin";
    user.password = "admin";
    user.hashPassword();
    user.role = "ADMIN";
    const userRepository = getRepository(User);
    await userRepository.save(user);
}

public async down(queryRunner: QueryRunner): Promise<any> {}
}

Now we start the server, so the synchronize tool can generate our database tables.

npm start

Now we can run the migration, to insert the first admin user.

npm run migration:run
