Installation

You need to be running Strapi 5.45.0 or higher to use this plugin.

npm install better-auth @strapi-community/plugin-better-auth
# or
yarn add better-auth @strapi-community/plugin-better-auth
# or
pnpm add better-auth @strapi-community/plugin-better-auth

Usage

1. Create a Better Auth config file

Create the Better Auth config file and add the following content.

// config/better-auth.ts
import { betterAuth } from "better-auth";
import { strapiAdapter } from '@strapi-community/plugin-better-auth';

const auth = () => betterAuth({
  database: strapiAdapter(),
  trustedOrigins: ['http://localhost:3000'],
  advanced: {
    database: {
      generateId: 'serial',
    },
  },
});

export default auth;

2. Generate the content types

Run the content type generation command to bootstrap the default content types.

npx auth@latest generate --config config/better-auth.ts

Tip: Every time you install a new Better Auth plugin, you have to run this command again.

3. Client implementation

Call the Better Auth API from your front-end:

// In your React/Vue/Svelte app
import { createAuthClient } from 'better-auth/react'; // or /vue, /svelte

const authClient = createAuthClient({
  baseURL: 'http://localhost:1337/api/auth',
});

// Sign up
await authClient.signUp.email({
  email: 'user@example.com',
  password: 'password123',
  name: 'John Doe',
});

4. Server side authentication

Use the Better Auth session to authenticate your users in custom Strapi controllers.

import { auth } from '@/lib/auth.ts';

// In a Strapi controller
export default {
  async customMethod(ctx) {
    // Use Better Auth API methods
    const session = await auth.api.getSession({
      headers: ctx.request.headers,
    });
    
    if (session) {
      // User is authenticated
      console.log('User:', session.user);
    }
  }
}

Supported plugins

Any Better Auth plugin may be used with Strapi + Better Auth. Some plugins require you to run the generate CLI in order to make the required schema changes. To do that you have to manually specify the location of the Better Auth config file.

npx auth@latest generate --config config/better-auth.ts
