// use case

Expose your Bun server publicly

1. 1

   Run Bun

   $ bun run server.ts

2. 2

   Tunnel

   $ lrok http 3000

3. 3

   Wire trust-proxy if your framework needs it

   Hono: c.req.header("x-forwarded-for") gives you the real client IP. Elysia: similar pattern. Bun.serve() exposes raw headers — read them directly.
