Better Auth has comprehensive starter examples for TanStack Start, Next.js, Remix, and Chrome Extension, but there's no Express.js starter example. The current Express integration docs only show fragments rather than a complete working setup.

I've been struggling to migrate to Better Auth in my existing Express project for days, likely due to conflicts or configuration issues in my complex codebase. A complete starter example would help developers like me identify what might be going wrong by comparing against a known working setup.
