Get Started with Drizzle and Nile

Step 1 - Install postgres package

Step 2 - Setup connection variables

Step 3 - Connect Drizzle ORM to the database

Step 4 - Create a table

Create a schema.ts file in the src/db directory and declare your tables. Since Nile is Postgres for multi-tenant apps, our schema includes a table for tenants and a todos table with a tenant_id column (we refer to those as tenant-aware tables):

import { pgTable, uuid, text, timestamp, varchar, vector, boolean } from "drizzle-orm/pg-core"
import { sql } from "drizzle-orm"

export const tenantsTable = pgTable("tenants", {
	id: uuid().default(sql`public.uuid_generate_v7()`).primaryKey().notNull(),
	name: text(),
	created: timestamp({ mode: 'string' }).default(sql`LOCALTIMESTAMP`).notNull(),
	updated: timestamp({ mode: 'string' }).default(sql`LOCALTIMESTAMP`).notNull(),
	deleted: timestamp({ mode: 'string' }),
});

export const todos = pgTable("todos", {
	id: uuid().defaultRandom(),
	tenantId: uuid("tenant_id"),
	title: varchar({ length: 256 }),
	estimate: varchar({ length: 256 }),
	embedding: vector({ dimensions: 3 }),
	complete: boolean(),
});

Step 5 - Setup Drizzle config file

Step 6 - Applying changes to the database

Step 7 - Seed and Query the database

Step 8 - Run index.ts file
