Error Boundaries

Summary

Deciding where in your component tree to place error boundaries so a single broken widget doesn't crash the entire page — an architectural, not just technical, decision.

How to Learn This

1Map your app's routes and widgets and decide where boundaries should sit.
2Wrap independent, non-critical widgets in their own boundary so failures stay contained.
3Design a consistent fallback UI pattern used across all your boundaries.
