Drizzle ORM Adapter

Drizzle ORM is a powerful and flexible ORM for Node.js and TypeScript. It provides a simple and intuitive API for working with databases, and supports a wide range of databases including MySQL, PostgreSQL, SQLite, and more. Read more here: Drizzle ORM.

Example Usage

Make sure you have Drizzle installed and configured. Then, you can use the Drizzle adapter to connect to your database.

import { betterAuth } from "better-auth";
import { drizzleAdapter } from "better-auth/adapters/drizzle";
import { db } from "./database.ts";
 
export const auth = betterAuth({
  database: drizzleAdapter(db, {
    provider: "sqlite", // or "pg" or "mysql"
  }), 
  //... the rest of your config
});

Schema generation & migration

The Better Auth CLI allows you to generate or migrate your database schema based on your Better Auth configuration and plugins.

To generate the schema required by Better Auth, run the following command:

npx @better-auth/cli@latest generate

To generate and apply the migration, run the following commands:

npx drizzle-kit generate # generate the migration file
npx drizzle-kit migrate # apply the migration

Additional Information

The Drizzle adapter expects the schema you define to match the table names. For example, if your Drizzle schema maps the user table to users, you need to manually pass the schema and map it to the user table.

import { betterAuth } from "better-auth";
import { db } from "./drizzle";
import { drizzleAdapter } from "better-auth/adapters/drizzle";
import { schema } from "./schema";
 
export const auth = betterAuth({
  database: drizzleAdapter(db, {
    provider: "sqlite", // or "pg" or "mysql"
    schema: {
      ...schema,
      user: schema.users,
    },
    //if all of them are just using plural form, you can just pass the option below
    usePlural: true,
  }),
});
