Foundations of Debugging Node.js
summary
A stepwise debugging recipe: start with console.log to validate assumptions, add structured JSON logging with Bunyan for timestamps and metadata, and aggregate logs to Papertrail to tail distributed services. Trigger the runtime debugger with a SIGUSR1 and use node-inspector to set breakpoints, inspect scope, and catch a swapped request/response signature that causes the failure. Several live demos show the fixes applied and the app returning expected responses.
