New Package: drizzle-seed

Note

drizzle-seed can only be used with drizzle-orm@0.36.4 or higher. Versions lower than this may work at runtime but could have type issues and identity column issues, as this patch was introduced in drizzle-orm@0.36.4

Full Reference

Basic Usage

In this example we will create 10 users with random names and ids

import { pgTable, integer, text } from "drizzle-orm/pg-core";
import { drizzle } from "drizzle-orm/node-postgres";
import { seed } from "drizzle-seed";

const users = pgTable("users", {
  id: integer().primaryKey(),
  name: text().notNull(),
});

async function main() {
  const db = drizzle(process.env.DATABASE_URL!);
  await seed(db, { users });
}

main();

Options

count

By default, the seed function will create 10 entities.
However, if you need more for your tests, you can specify this in the seed options object

await seed(db, schema, { count: 1000 });

seed

If you need a seed to generate a different set of values for all subsequent runs, you can define a different number
in the seed option. Any new number will generate a unique set of values

await seed(db, schema, { seed: 12345 });

Features

Added OVERRIDING SYSTEM VALUE api to db.insert()

If you want to force you own values for GENERATED ALWAYS AS IDENTITY columns, you can use OVERRIDING SYSTEM VALUE

As PostgreSQL docs mentions

In an INSERT command, if ALWAYS is selected, a user-specified value is only accepted if the INSERT statement specifies OVERRIDING SYSTEM VALUE. If BY DEFAULT is selected, then the user-specified value takes precedence

await db.insert(identityColumnsTable).overridingSystemValue().values([
  { alwaysAsIdentity: 2 },
]);

Added .$withAuth() API for Neon HTTP driver

Using this API, Drizzle will send you an auth token to authorize your query. It can be used with any query available in Drizzle by simply adding .$withAuth() before it. This token will be used for a specific query

Examples

const token = 'HdncFj1Nm'

await db.$withAuth(token).select().from(usersTable);
await db.$withAuth(token).update(usersTable).set({ name: 'CHANGED' }).where(eq(usersTable.name, 'TARGET'))
