7# TypeScript errors — use `nostics`
8 
9Define and report user-facing errors through **`nostics`** in `apps/native/src/lib/errors.ts`.
10 
11- Add diagnostic codes, titles, suggestions, and `defineDiagnostics` entries there — not ad hoc strings in components.
12- Import `diagnostics` (or helpers like `getRebuildErrorTitle`) from `@/lib/errors` when surfacing errors in UI.
13- Rust-side errors exposed to the frontend should map to stable codes that have entries in `errors.ts`.

15```typescript
16// ❌ BAD — one-off error copy in a component
17toast.error("Something went wrong with the provider");
18 
19// ✅ GOOD — structured diagnostic
20import { diagnostics, DIAGNOSTIC_CODES } from "@/lib/errors";
21diagnostics.report(DIAGNOSTIC_CODES.EVOLVE_NO_PROVIDER);
