Lift Off! Building REST APIs that Fly

on YouTube ↗20m

" summary

A deployed Plumber REST API switches its JSON serializer to yyjsonr and adds async worker processes via mirai, cutting per-request serialization overhead and preventing synchronous queuing. An example shows one slow 10s request blocking 2s ones until async workers (four spawned in the demo) handle them concurrently; business logic needs no rewrite and endpoints return promises immediately. The concrete outcome: the service scales to meet higher traffic and restores responsiveness.
