Error handling in Nodejs is the programmatic practice of anticipating, catching, and responding to functional anomalies or runtime failures within a server application. Implementing robust error handling ensures your backend application isolates unexpected failures gracefully, prevents sudden server crashes, maintains high availability, and provides actionable logs for debugging. Without a bulletproof error handling strategy, a single unhandled exception or failed database queries can compromise your entire event loop. When an unhandled error pops up, the Node.js process terminates abruptly. This drops active user connections and leaves your application state broken. Building a centralized architecture keeps your application reliable, secure, and resilient under heavy production workloads.
