📝 Walkthrough

Walkthrough

The Fastify example server startup was refactored from an immediately-invoked async function with callback-based error handling to top-level await syntax. The listen options now explicitly specify host: '127.0.0.1', and the address handling is performed after the await completes rather than within a callback.

Changes

Cohort / File(s)	Summary
Server Startup Pattern Refactor examples/fastify/index.js	Replaced immediately-invoked async function with top-level await. Converted callback-based fastify.listen({ port: 3000 }, (err, address) => ...) to async/await await fastify.listen({ host: '127.0.0.1', port: 3000 }). Added explicit host specification and moved logging logic to execute after await completes.

Poem

🐰 Hops of joy through async paths,
Callbacks fade like morning baths,
Top-level await takes the lead,
Clean and modern, yes indeed!
