Drizzle is a modern ORM for TypeScript that provides a simple and type-safe way to interact with your database. This guide demonstrates how to connect your application to a Lakebase Postgres database using Drizzle ORM.

To connect a TypeScript/Node.js project to Neon using Drizzle ORM, follow these steps:

Create a new directory for your project and navigate into it:

mkdir my-drizzle-neon-project
cd my-drizzle-neon-project

Initialize a new Node.js project with a package.json file:

npm init -y

If you do not have one already, create a Neon project.

1. Navigate to the Projects page in the Neon Console.
2. Click New Project.
3. Specify your project settings and click Create Project.

Find your database connection string by clicking the Connect button in the Console nav to open the Connect to your branch modal. Select a branch, a user, and the database you want to connect to. A connection string is constructed for you. The connection string includes the user name, password, hostname, and database name.

Create a .env file in your project's root directory and add the connection string to it. Your .env file should look like this:

# Pooled connection for your application
DATABASE_URL="postgresql://[user]:[password]@[endpoint]-pooler.[region].aws.neon.tech/[dbname]?sslmode=require"

# Unpooled connection for Drizzle Kit
DATABASE_URL_UNPOOLED="postgresql://[user]:[password]@[endpoint].[region].aws.neon.tech/[dbname]?sslmode=require"

Note: Neon supports both direct and pooled connection strings, which you can find by clicking the Connect button in the Console nav. A pooled connection string (the hostname includes -pooler) routes through a PgBouncer connection pool, which is ideal for your application at runtime. However, using a pooled connection string for migrations can lead to errors. Use a direct (non-pooled) connection when running Drizzle Kit migrations. For more information, see Connection pooling and Schema migration with Drizzle ORM.

Install Drizzle ORM, Drizzle Kit for migrations, and your preferred database driver. Choose one of the following drivers based on your application's needs:

Neon Serverless (HTTP)

Use the Neon serverless HTTP driver for serverless environments (for example, Vercel, Netlify).

npm install drizzle-orm @neondatabase/serverless dotenv
npm install -D drizzle-kit

Neon WebSocket

Use the Neon WebSocket driver for long-running applications that require a persistent connection (for example, a standard Node.js server).

npm install drizzle-orm @neondatabase/serverless ws dotenv
npm install -D drizzle-kit @types/ws

node-postgres

Use the classic node-postgres (pg) driver, a widely-used and stable choice for Node.js applications.

npm install drizzle-orm pg dotenv
npm install -D drizzle-kit @types/pg

postgres.js

Use the postgres.js driver, a modern and lightweight Postgres client for Node.js.

npm install drizzle-orm postgres dotenv
npm install -D drizzle-kit

Drizzle Kit uses a configuration file to manage schema and migrations. Create a drizzle.config.ts file in your project root and add the following content. This configuration tells Drizzle where to find your schema and where to output migration files.

import 'dotenv/config';
import { defineConfig } from 'drizzle-kit';

if (!process.env.DATABASE_URL_UNPOOLED) {
  throw new Error('DATABASE_URL_UNPOOLED is not set in the .env file');
}

export default defineConfig({
  schema: './src/schema.ts', // Your schema file path
  out: './drizzle', // Your migrations folder
  dialect: 'postgresql',
  dbCredentials: {
    url: process.env.DATABASE_URL_UNPOOLED,
  },
});

Tip: Loading a .env.local file

import 'dotenv/config' loads variables from a .env file. If you keep your connection string in .env.local (a common convention in Next.js and other frameworks), point dotenv at it explicitly instead:

import { config } from 'dotenv';
config({ path: '.env.local' });

import { defineConfig } from 'drizzle-kit';

if (!process.env.DATABASE_URL_UNPOOLED) {
  throw new Error('DATABASE_URL_UNPOOLED is not set in .env.local');
}

// ...rest of config unchanged

Create a file: src/db.ts, to initialize and export your Drizzle client. The setup varies depending on the driver you installed.

Neon Serverless (HTTP)

import 'dotenv/config';
import { drizzle } from 'drizzle-orm/neon-http';
import { neon } from '@neondatabase/serverless';

const sql = neon(process.env.DATABASE_URL!);
export const db = drizzle(sql);

Neon WebSocket

import 'dotenv/config';
import { drizzle } from 'drizzle-orm/neon-serverless';
import { Pool, neonConfig } from '@neondatabase/serverless';
import ws from 'ws';

// For Node.js environments older than v22, you must provide a WebSocket constructor
neonConfig.webSocketConstructor = ws;

// To work in edge environments (Cloudflare Workers, Vercel Edge, etc.), enable querying over fetch
// neonConfig.poolQueryViaFetch = true

const pool = new Pool({ connectionString: process.env.DATABASE_URL! });
export const db = drizzle(pool);

node-postgres

import 'dotenv/config';
import { drizzle } from 'drizzle-orm/node-postgres';
import { Pool } from 'pg';

const pool = new Pool({
  connectionString: process.env.DATABASE_URL!,
});

export const db = drizzle(pool);

postgres.js

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

const client = postgres(process.env.DATABASE_URL!);
export const db = drizzle(client);

Drizzle uses a schema-first approach, allowing you to define your database schema using TypeScript. This schema will be used to generate migrations and ensure type safety throughout your application.

The following example defines a schema for a simple demo_users table. Create a src/schema.ts file and add the following content:

import { pgTable, serial, text } from 'drizzle-orm/pg-core';

export const demoUsers = pgTable('demo_users', {
  id: serial('id').primaryKey(),
  name: text('name'),
});

After defining your schema, you can generate migration files with Drizzle Kit. This will create the necessary SQL files to set up your database schema in Neon.

npx drizzle-kit generate

You should see output similar to the following, indicating that migration files have been created:

$ npx drizzle-kit generate
No config path provided, using default 'drizzle.config.ts'
Reading config file '/home/user/drizzle/drizzle.config.ts'
1 tables
demo_users 2 columns 0 indexes 0 fks

[✓] Your SQL migration file ➜ drizzle/0000_clever_purple_man.sql 🚀

You can find the generated SQL migration files in the drizzle directory specified in your drizzle.config.ts.

Apply the generated migrations (SQL files) to your Neon database using Drizzle Kit. This command will use the drizzle.config.ts file for database connection details and apply the migrations to your Neon database.

npx drizzle-kit migrate

You should see output similar to the following, indicating that the migrations have been applied successfully:

$ npx drizzle-kit migrate
No config path provided, using default 'drizzle.config.ts'
Reading config file '/home/user/drizzle/drizzle.config.ts'
Using 'pg' driver for database querying

You can verify that the demo_users table has been created in your Neon database by checking the Tables section in the Neon Console.

Create a file: src/index.ts, to interact with your database using the Drizzle client. Here's an example of inserting a new user and querying all users from the demo_users table:

Neon Serverless (HTTP)

import { db } from './db';
import { demoUsers } from './schema';

async function main() {
  try {
    await db.insert(demoUsers).values({ name: 'John Doe' });
    const result = await db.select().from(demoUsers);
    console.log('Successfully queried the database:', result);
  } catch (error) {
    console.error('Error querying the database:', error);
  }
}

main();

Neon WebSocket / node-postgres / postgres.js

import { db } from './db';
import { demoUsers } from './schema';

async function main() {
  try {
    await db.insert(demoUsers).values({ name: 'John Doe' });
    const result = await db.select().from(demoUsers);
    console.log('Successfully queried the database:', result);
  } catch (error) {
    console.error('Error querying the database:', error);
  } finally {
    // Close the database connection to ensure proper shutdown for Neon WebSocket, node-postgres, and postgres.js drivers
    await db.$client.end();
  }
}

main();

Run the script using tsx:

npx tsx src/index.ts

You should see output similar to the following, indicating that the user was inserted and queried successfully:

Successfully queried the database: [ { id: 1, name: 'John Doe' } ]

You can point Drizzle at different Neon branches per environment by selecting the connection string based on NODE_ENV (or any other environment variable):

import { drizzle } from 'drizzle-orm/neon-http';
import { neon } from '@neondatabase/serverless';

const getBranchUrl = () => {
  const env = process.env.NODE_ENV;
  if (env === 'development') return process.env.DEV_DATABASE_URL;
  if (env === 'test') return process.env.TEST_DATABASE_URL;
  return process.env.DATABASE_URL;
};

const sql = neon(getBranchUrl()!);
export const db = drizzle({ client: sql });

Each branch has its own connection string, available in the Neon Console or via the CLI (neon connection-string <branch-id-or-name> --project-id <project-id>).
