Drizzle <> PostgreSQL

This guide assumes familiarity with:

Drizzle has native support for PostgreSQL connections with the node-postgres and postgres.js drivers.

There are a few differences between the node-postgres and postgres.js drivers that we discovered while using both and integrating them with the Drizzle ORM. For example:

node-postgres

Step 1 - Install packages

npm
yarn
pnpm
bun
npm i drizzle-orm pg
npm i -D drizzle-kit @types/pg

Step 2 - Initialize the driver and make a query

node-postgres
node-postgres with config
// Make sure to install the 'pg' package 
import { drizzle } from 'drizzle-orm/node-postgres';

const db = drizzle(process.env.DATABASE_URL);
 
const result = await db.execute('select 1');

If you need to provide your existing driver:

// Make sure to install the 'pg' package 
import { pgTable, serial, text, varchar } from "drizzle-orm/pg-core";
import { drizzle } from "drizzle-orm/node-postgres";
import { Pool } from "pg";

const pool = new Pool({
  connectionString: process.env.DATABASE_URL,
});
const db = drizzle({ client: pool });
 
const result = await db.execute('select 1');

postgres.js

Step 1 - Install packages

npm
yarn
pnpm
bun
npm i drizzle-orm postgres
npm i -D drizzle-kit

Step 2 - Initialize the driver and make a query

postgres.js
postgres.js with config
import { drizzle } from 'drizzle-orm/postgres-js';

const db = drizzle(process.env.DATABASE_URL);

const result = await db.execute('select 1');

If you need to provide your existing driver:

// Make sure to install the 'postgres' package
import { drizzle } from 'drizzle-orm/postgres-js';
import postgres from 'postgres';

const queryClient = postgres(process.env.DATABASE_URL);
const db = drizzle({ client: queryClient });

const result = await db.execute('select 1');
