debugging-first

Debugging systematically means gathering evidence first—check console logs, network traffic, and application state before modifying code. This evidence-first approach eliminates guesswork by identifying the root cause through structured investigation of logs, network requests, and runtime state across browser, server, and CI environments.

Start with console logs and network traffic to capture error messages and failed requests. Prioritize these checks before inspecting code, then move to application state inspection if needed. This ordered workflow—logs, network, state, code—ensures you've collected diagnostic evidence before attempting fixes.

Yes, evidence-first debugging applies to web and server applications including login failures, UI rendering issues, API errors, and performance regressions. Collect structured evidence from console logs, network traffic, and application state in browser, server, and CI environments before modifying code.

After making a targeted fix based on collected evidence, verify the fix by reproducing the original problem and confirming it no longer occurs. This verification step completes the disciplined debugging workflow and ensures your minimal, evidence-driven changes address the root cause.

Capturing logs and reproducing issues before editing creates a record of the problem's symptoms and conditions. This evidence enables hypothesis testing and targeted, minimal fixes rather than trial-and-error changes, reducing time spent on incorrect solutions.
