Shows friendly fallback UI with Try Again and Reload buttons instead of white screen crash.

Currently, any JavaScript error in a component causes a complete app crash. Error boundaries would allow the app to display a fallback UI and potentially recover. This is especially important for production use where you can't predict all error conditions. - -**Implementation Notes:** -- Create a generic `ErrorBoundary` component with fallback UI -- Wrap top-level pages (TrackerPage, BillsPage, AnalyticsPage) in error boundaries -- Wrap App.jsx router with error boundary -- Log errors to console and optionally to error tracking service -- Consider adding `componentDidCatch` class component wrapper for critical paths -- Files likely to be modified: Add new `client/components/ErrorBoundary.jsx`, wrap pages in App.jsx -- Estimated effort: 45-60 minutes - ### No Transaction Wrapping for Migrations **Priority:** CRITICAL **Status:** PENDING diff --git a/HISTORY.md b/HISTORY.md index 0959bb8..b4e3d13 100644 --- a/HISTORY.md +++ b/HISTORY.md @@ -2,6 +2,9 @@ ## v0.19.2 +### Added +- **React Error Boundaries** — `ErrorBoundary` component wraps all routes in `App.jsx`.
