Summary

When a component throws a rendering error, the entire app crashes to the "Fatal Error" screen. This happens because we only have two top-level ErrorBoundary wrappers (in App.tsx) and one feature-scoped boundary (in GetCardData.tsx for report charts).

Adding scoped ErrorBoundary components around major features would contain failures to the affected area instead of taking down the whole app.

Problem

A single rendering error in any feature — budget, accounts, transactions, reports, schedules, rules — crashes the entire application. Users lose all context and must restart.

This is a recurring pattern. Across open and closed issues, there are 70+ reports of fatal crashes caused by component-level errors that could have been contained:

Currently open:

  • #7273 — Fatal Error after reports .json file import
  • #7285 — Fatal Error viewing ledgers with recurring transactions ending in the past
  • #7098 — Custom Report bars crash
  • #7108 — Calendar widget crashes on mobile
  • #6073 — Hide reconciled transactions crashes app
  • #7358 — Dollar sign in Schedule Name crashes app
  • #6317 — Backslash in rule notes causes crash
  • #5351 — API Unhandled Rejection

Recurring crash patterns from closed issues:

The fix for #4703 (adding an ErrorBoundary around modals) shows this approach works. We should apply it systematically.

Proposed approach

Wrap major feature areas with ErrorBoundary from react-error-boundary (already a dependency at v6.0.3). Each boundary should:

  1. Catch and contain the error to that feature area
  2. Show a contextual fallback (e.g., "This report couldn't be loaded" instead of a full-app fatal screen)
  3. Offer a retry via resetErrorBoundary where it makes sense

Suggested areas to add boundaries

Area Entry point(s) Related crashes
Budget table BudgetTable / BudgetPageHeader #5969, #6073
Account ledger Account component #7285, #3263, #595
Transaction list TransactionList #5304, #1021
Reports (individual) Each report view #7273, #7098, #5814, #5764, #6221
Schedules Schedules page #7358, #3989, #3954
Rules Rules page #6317, #6885, #4013, #2180
Sidebar Sidebar component #5467
Dashboard widgets Individual widget cards #7108, #6313
Individual modals Each modal content (container boundary exists) #4703 pattern

Implementation notes

  • react-error-boundary v6 is already a dependency — no new packages needed
  • FatalError.tsx has good patterns for error display that can be adapted
  • A shared FeatureErrorFallback component could keep UX consistent across boundaries
  • Each boundary can use onError to log to the existing notification system

This is a good first contribution

Each boundary is a small, self-contained change — pick one area from the table above. The pattern is straightforward:

import { ErrorBoundary } from 'react-error-boundary';

<ErrorBoundary FallbackComponent={FeatureErrorFallback}>
  <YourFeatureComponent />
</ErrorBoundary>

This happens because we only have two top-level `ErrorBoundary` wrappers (in `App.tsx`) and one feature-scoped boundary (in `GetCardData.tsx` for report charts).
