SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides guidance to implement frontend authentication flows using Better Auth and JWT for secure, scalable client-side auth.

Core Features & Use Cases

  • Centralizes authentication patterns for signup, signin, signout, session management, and protected routes in frontend apps.
  • Demonstrates how to attach JWT tokens to API requests, handle 401 errors, and redirect users to login when needed.
  • Real-world use case: quickly scaffold a secure frontend login workflow with token persistence and guarded routes.

Quick Start

Configure Better Auth with JWT plugin, implement sign-up and sign-in flows as described, and wire protected routes to enforce authentication.

FAQPage Schema
How do I handle 401 errors and redirect users to login when JWT sessions expire?

Handling 401 errors during JWT sessions involves intercepting failed API calls, clearing invalid tokens, and safely redirecting users to the login page to restore secure session management and protected route access.

What's the best way to attach JWT tokens to API requests in single-page applications?

Attaching JWT tokens to API requests requires setting automatic Authorization headers for guarded routes. This ensures secure frontend authentication flows consistently pass credentials to validate protected resources.

Does Better Auth work with JWT for frontend signup and login workflows?

Better Auth works with JWT by using its plugin to scaffold frontend signup, signin, and session management. This integration secures modern single-page applications by centralizing token persistence and protected routes.

How do I implement protected routes for dashboards using token-based session management?

Implementing protected routes for dashboards uses token-based session management to guard API calls. It validates JWT tokens on navigation, blocking unauthorized access and redirecting unauthenticated users to login.

Why do I need automatic Authorization headers for frontend authentication flows?

Automatic Authorization headers are needed for frontend authentication flows to securely attach JWT tokens to outgoing API requests. This mechanism prevents manual token injection errors and maintains valid session states across guarded features.

Can I use Better Auth for signout and session management across multiple frontend features?

You can use Better Auth for signout and session management across multiple frontend features. It centralizes authentication patterns to safely invalidate tokens, clear persistent storage, and enforce secure guarded routes.
