Start with a reproducible failure and identify whether it occurs on the client, server, or both. Choose a debugging or profiling tool based on that evidence.

The debugging mindset

1. Reproduce it. If you can't reproduce it, you can't fix it.
2. Isolate it. Remove systems until the bug disappears; the last thing removed is the cause.
3. Measure it. Use tools instead of guessing.
4. Fix one thing at a time. Verify the fix and add a regression test if possible.
5. Log defensively. Good logs make future debugging faster.
