Error Boundaries Save You From Crashes! Here's How to Use It
summary
Shows an actual banking demo that uses a Mirage JS mock API and flips a 500 response to prove one failing widget can unmount the whole tree unless wrapped. Demonstrates replacing a blank crash with a customizable fallback UI, and argues to wrap components individually so one error only hides its own part. Lists practical limits: no capture for event handlers, async code, server‑side rendering, or errors thrown inside the boundary itself, and suggests sending error alerts for ops.
