Authentication is a critical component of any web application. Better Auth provides a modern, type-safe solution for SvelteKit applications.

Why Better Auth?

Better Auth offers several advantages:

  • **Framework agnostic core**: Works with any JavaScript framework
  • **Multiple providers**: Support for email/password, OAuth, and more
  • **Session management**: Built-in session handling with secure defaults

    • Implementation

    First, install the necessary dependencies:

    pnpm add better-auth @better-auth/drizzle

    Create your auth configuration:

    import { betterAuth } from 'better-auth';

    export const auth = betterAuth({

    database: drizzleAdapter(db),

    providers: {

    emailAndPassword: {

    enabled: true

    }

    }

    });

    Security Considerations

  • Always use HTTPS in production
  • Implement rate limiting on auth endpoints
  • Use secure session cookies
  • Validate and sanitize all inputs

    • Conclusion

    Better Auth simplifies authentication while maintaining security best practices.
