Seeding your database

You can seed your database with initial data though the CLI.

Seeding the database is useful to:

• Reload the data frequently the database in development or test.
• Set initial data in production.

Migrations can be used to add or modify data to an existing database (data migration phase).

Configuring the seeder function

Each database can be configured with a seeder function.

import { defineDatabase } from "@monolayer/pg/schema";
import { dbSchema } from "./schema";
import { dbSchema } from "./seeds";

export default defineDatabase({
  id: "default",
  schemas: [dbSchema],
  extensions: [],
  camelCase: false,
  seeder: dbSeed, 
});

Loading seed data

To load the seed data into the database execute the db seed command:

npx monolayer db seed

This command will call the seeder function defined in your database definition.
