Saimon Sharif - We'll do it live: Underhanded Debugging Tactics

on YouTube ↗27m

" summary

Practical checklist of reproducible tactics for debugging bugs that only appear in production: rule out CDN and caching by bypassing CDN and flushing caches, recover readable code with source maps and set conditional breakpoints in Chrome DevTools, extract props via JSON.stringify and inspect with jq, replay requests with curl or import into Postman, run scripted high-frequency requests to reproduce race conditions, capture traffic with tcpdump (analyze with Wireshark), and temporarily remove a node from the load balancer to deploy breakpoints or extra logging.
