Node.js Services Development (LFW212) Node.js developers often misjudge async error handling in microservices—treating promise rejections as optional rather than architectural imperatives. LFW212 specifically probes whether you can architect resilient service layers where unhandled rejections crash nothing, middleware chains remain intact, and distributed tracing across services actually works in production scenarios.
