Drizzle with Vercel Edge Functions

Install the @neondatabase/serverless driver

Install the @neondatabase/serverless driver:

npm i @neondatabase/serverless

yarn add @neondatabase/serverless

pnpm add @neondatabase/serverless

bun add @neondatabase/serverless

Create a table

Create a schema.ts file in the src/db directory and declare a table schema:

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

export const usersTable = pgTable('users_table', {
  id: serial('id').primaryKey(),
  name: text('name').notNull(),
  age: text('age').notNull(),
  email: text('email').notNull().unique(),
})

Setup Drizzle config file

Drizzle config - a configuration file that is used by Drizzle Kit and contains all the information about your database connection, migration folder and schema files.

Create a drizzle.config.ts file in the root of your project and add the following content:

import { defineConfig } from "drizzle-kit";

export default defineConfig({
  schema: "./src/db/schema.ts",
  dialect: "postgresql",
  dbCredentials: {
    url: process.env.POSTGRES_URL!,
  },
});

Configure your database connection string in the .env file:

POSTGRES_URL="postgres://[user]:[password]@[host]-[region].aws.neon.tech:5432/[db-name]?sslmode=[ssl-mode]"

Applying changes to the database

You can generate migrations using drizzle-kit generate command and then run them using the drizzle-kit migrate command.

Generate migrations:

npx drizzle-kit generate

These migrations are stored in the drizzle directory, as specified in your drizzle.config.ts. This directory will contain the SQL files necessary to update your database schema and a meta folder for storing snapshots of the schema at different migration stages.

Example of a generated migration:

CREATE TABLE IF NOT EXISTS "users_table" (
	"id" serial PRIMARY KEY NOT NULL,
	"name" text NOT NULL,
	"age" text NOT NULL,
	"email" text NOT NULL,
	CONSTRAINT "users_table_email_unique" UNIQUE("email")
);

Run migrations:

npx drizzle-kit migrate

Alternatively, you can push changes directly to the database using Drizzle kit push command:

npx drizzle-kit push

Connect Drizzle ORM to your database

Create a index.ts file in the src/db directory and set up your database configuration:

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


export const db = drizzle(process.env.POSTGRES_URL!)

Create an API route

Create route.ts file in src/app/api/hello directory. To learn more about how to write a function, see the Functions API Reference and Vercel Functions Quickstart.

import { db } from "@/db";
import { usersTable } from "@/db/schema";
import { NextResponse } from "next/server";

export const dynamic = 'force-dynamic'; // static by default, unless reading the request
export const runtime = 'edge' // specify the runtime to be edge

export async function GET(request: Request) {
  const users = await db.select().from(usersTable)

  return NextResponse.json({ users, message: 'success' });
}

Test your code locally

{
  "users": [],
  "message": "success"
}
