Beta docs content is synced from the next branch at build time, so it can reference MDX components that don't exist in the deploying branch's app code. When GenerateAppleJwt was removed on main (#9938) while next still used it, prerendering /docs/beta/authentication/apple crashed the whole Vercel build with "Expected component `GenerateAppleJwt` to be defined". Scan each beta page's markdown for component-like JSX tags and provide a fallback for any tag the app doesn't supply, so cross-branch content drift degrades to a visible callout instead of a failed deploy. Stable pages keep the hard failure since their content and components ship from the same commit.
Better Auth
Better Auth is a framework-agnostic authentication (and authorization) framework for TypeScript. It provides a comprehensive set of features out of the box and includes a plugin ecosystem that simplifies adding advanced functionalities with minimal code in a short amount of time. Whether you need 2FA, multi-tenant support, or other complex features, it lets you focus on building your actual application instead of reinventing the wheel.
Why Better Auth
Authentication in the TypeScript ecosystem is a half-solved problem. Other open-source libraries often require a lot of additional code for anything beyond basic authentication. Rather than just pushing third-party services as the solution, I believe we can do better as a community—hence, Better Auth.
