Data factories

Is there a good way to add a data factory to Drizzle, so that I can add new users quickly for testing etc. (Ideally with being able to pass through relationship data as well).

There is no seeding helper from drizzle. You have to create your own script to seed your database however you please I have a seed.ts file in my drizzle/ folder and it looks like this:

dotenv.config();

const { hash } = pkg;

// create the connection
const poolConnection = mysql.createPool({
  host: process.env.DATABASE_HOST,
  user: process.env.DATABASE_USER,
  database: process.env.DATABASE_NAME,
  password: process.env.DATABASE_PASSWORD,
  timezone: "+00:00"
});
console.log(process.env.DATABASE_PASSWORD);

const db = drizzle(poolConnection, { schema, logger: true });
const COMPANY_NAME = "Test Company";
const USERS: NewUser[] = [
  {
    id: generateId(),
    username: "userOwner",
    firstName: "Fname",
    lastName: "Lname",
    email: "[email protected]",
    password: await hash("fname", 12),
    role: "owner"
  },
  ...
];
await db.insert(company).values({name: COMPANY_NAME, id: generateId()});
await db.insert(users).values(USERS);
...

dotenv.config();

const { hash } = pkg;

// create the connection
const poolConnection = mysql.createPool({
  host: process.env.DATABASE_HOST,
  user: process.env.DATABASE_USER,
  database: process.env.DATABASE_NAME,
  password: process.env.DATABASE_PASSWORD,
  timezone: "+00:00"
});
console.log(process.env.DATABASE_PASSWORD);

const db = drizzle(poolConnection, { schema, logger: true });
const COMPANY_NAME = "Test Company";
const USERS: NewUser[] = [
  {
    id: generateId(),
    username: "userOwner",
    firstName: "Fname",
    lastName: "Lname",
    email: "[email protected]",
    password: await hash("fname", 12),
    role: "owner"
  },
  ...
];
await db.insert(company).values({name: COMPANY_NAME, id: generateId()});
await db.insert(users).values(USERS);
...

I have this entry in my package.json: "seed": "pnpm with-env ts-node --esm drizzle/run-seed.ts" And then I just run it with pnpm seed
