Debugging Env Var Issues
A concise checklist for incidents where local works but CI, staging, or production changes behavior.
Debugging Cache Stampedes
How to recognize and contain request spikes when cached data expires.
Debugging CORS Origin Bugs
A practical way to inspect origin parsing, credentials, and header behavior.
Debugging Retry Bugs
Retry issues often hide the first failure and create duplicate work.
Debugging Timezone Bugs
Time bugs usually live at day boundaries, DST changes, and unit conversions.
Debugging Pagination Bugs
Pagination bugs hide in boundary math, cursor reuse, and new records arriving between pages.
Structured investigations for the failure modes engineers meet in real systems.
Diagnosing Nuxt Hydration Mismatch Errors in Production
Hydration mismatch errors in Nuxt apps break SSR interactivity and can be tough to pinpoint. This guide walks through investigating, reproducing, and fixing these.
Vue Router Navigation Guard Blocking Route Transitions
Diagnose and resolve Vue Router navigation guards unexpectedly blocking route changes. Covers subtle mistakes and issues beyond standard docs.
Why Your Vue Composition API ref Isn’t Reactive
Vue’s Composition API refs sometimes fail to trigger reactivity. This guide covers subtle causes, practical debugging, and real-world fixes for non-reactive refs.
Diagnosing Missing Cookies in Nuxt SSR Server Context
Nuxt SSR often fails to read cookies server-side if headers are misrouted or missing. This guide shows where things break and how to reliably retrieve cookies in SSR.
Vue Watcher Causing Infinite Render Loop
Vue watch handlers sometimes trigger infinite update cycles. This guide detangles the real causes, not just the basics, and shows how to fix them.
Pinia Store State Not Persisting Across Page Reloads
Diagnosing and fixing issues when your Pinia store state resets on page reloads—even with plugins or localStorage configured.
Long-form thinking on debugging habits, observability, and the systems around the bug.
Five Debugging Habits That Separate Seniors from Juniors
It's not tools. It's not years of experience. It's five repeatable habits that senior engineers do reflexively and juniors haven't built yet.
Why Your Production Logs Are Lying to You
Logs tell you what the code reported. They almost never tell you what actually happened. Here is the gap, and how to close it.
The Real Cost of Console.log Debugging (and What to Use Instead)
Every engineer reaches for console.log. Most do not think about what it costs — in time, in performance, or in production readiness. Here is the honest accounting.
Interpreting Stack Traces: Practical Steps for Faster Debugging
Stack traces can be dense, but reading them fluently accelerates triage and root cause analysis. This article explains how to extract actionable information, with real-world context.
Efficient Debugging with git bisect: Going Beyond Binary Search
This article explains how to incorporate git bisect into your debugging workflow, focusing on practical execution, automation, and common edge cases.
Applying Rubber Duck Debugging to Complex Engineering Problems
Rubber duck debugging isn’t just a quirky solo exercise. I’ll show how explaining code out loud surfaces misunderstandings and reduces wasted team cycles.
