Installation

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

Usage

1. Install the plugin in your Strapi application

Add the plugin to your Strapi plugins configuration:

// config/plugins.ts
export default {
  'better-auth': {
    enabled: true,
  }
}

2. Customize the Better Auth options

The Better Auth options can be customized through the plugin config:

// config/plugins.ts
export default {
  'better-auth': {
    enabled: true,
    config: {
      betterAuthOptions: {
        emailAndPassword: {
          enabled: true,
          requireEmailVerification: true,
        },
        socialProviders: {
          github: {
            clientId: process.env.GITHUB_CLIENT_ID!,
            clientSecret: process.env.GITHUB_CLIENT_SECRET!,
          },
          google: {
            clientId: process.env.GOOGLE_CLIENT_ID!,
            clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
          },
        },
        session: {
          expiresIn: 60 * 60 * 24 * 7, // 7 days
        },
      },
    },
  },
};

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/better-auth',
});

// Sign up
await authClient.signUp.email({
  email: '[email protected]',
  password: 'password123',
  name: 'John Doe',
});

4. Server side authentication

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

// In a Strapi controller
export default {
  async customMethod(ctx) {
    // Access the Better Auth instance
    // @ts-expect-error - Accessing custom property
    const auth = strapi.betterAuth;
    
    // 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, but only a subset are considered supported for the integration. Strapi + Better Auth works out of the box for these without any required schema changes.
