Example Usage

Make sure you have MySQL installed and configured. Then, you can connect it straight into Better Auth.

import { betterAuth } from "better-auth";
import { createPool } from "mysql2/promise";
 
export const auth = betterAuth({
  database: createPool({
    host: "localhost",
    user: "root",
    password: "password",
    database: "database",
  }),
});

Schema generation & migration

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

npx @better-auth/cli@latest generate

npx @better-auth/cli@latest migrate
