About This Skill
What it does
This skill, "Using Authentication," leverages Better Auth to enable secure client and server-side authentication within applications. It facilitates managing user sessions, protecting routes, implementing sign-in/sign-out functionality, and retrieving user data. The skill provides patterns for both React components (client-side) and Server Components/API routes (server-side).
When to use it
- Building web applications requiring secure user login and access control.
- Creating protected pages that should only be accessible to authenticated users.
- Implementing sign-in and sign-out flows for users.
- Fetching user data after a successful authentication.
- Redirecting unauthenticated users to a sign-in page or redirecting authenticated users away from auth pages.
Key capabilities
- Client-side session management using React hooks (
useSession,signOut). - Server-side session access in Server Components and API routes.
- Protected route implementation with authentication checks.
- Sign-in functionality via email/password or social providers (specific provider details not specified).
- Redirection of unauthenticated users to sign-in pages.
- Redirection of authenticated users away from authentication pages.
Example prompts
- "Show me how to use
useSessionin a React component." - "How do I get the user's session data in an API route?"
- "Implement a protected page that redirects unauthenticated users."
Tips & gotchas
- This skill requires integration with Better Auth and related libraries (e.g.,
next/headers,next/navigation). - The specific implementation details for social sign-in are not provided in the source content.
