SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides developers in adding robust authentication layers to TypeScript and JavaScript apps using Better Auth, removing guesswork and reducing security risks.

Core Features & Use Cases

  • Core setup: identify framework, choose database, install better-auth, create auth.ts and auth-client.ts, set up route handler, run migrations, and extend with plugins.
  • Configuration: environment variables such as BETTER_AUTH_SECRET and BETTER_AUTH_URL; OAuth secrets for providers like GitHub and Google.
  • Server Config (auth.ts): minimal required config and progressively richer setups with socialProviders, email verification, plugins, and session settings.
  • Client Config (auth-client.ts): framework-specific imports and common exports for signIn, signUp, signOut, useSession, getSession.
  • Route Handler Setup: per-framework file mappings (Next.js, Express, SvelteKit, SolidStart, Hono, etc.) to wire authentication flows.
  • Database Migrations & Adapters: guidance for migrating or setting up the chosen database with the authentication schema.
  • Plugins & Extensibility: guidance on adding 2FA, SSO, admin tooling, and other plugins to extend authentication capabilities.

Quick Start

Set up a TypeScript/JavaScript project, install Better Auth, and configure server and client authentication following the installation, server config, client config, and route handler guidance to enable a secure auth flow.
