# Jotai Reactive Atoms

## Patterns

| Pattern | Use Case | Details |
|---------|----------|---------|
| Hybrid Atom | Real-time + HTTP fallback | [HYBRID-ATOM.md](HYBRID-ATOM.md) |
| Stream Atom | IPC subscriptions | [EVENT-SUBSCRIPTION.md](EVENT-SUBSCRIPTION.md) |
| Write Atom | CRUD mutations | [WRITE-ATOM.md](WRITE-ATOM.md) |

## Key Rules

1. **Hybrid atom getter must NOT be async** - use sync conditional
2. **Always debounce IPC handlers** - prevent UI thrashing
3. **Refresh read atoms after mutations** - `set(singleFetchAtom)`

## Quick Example

```typescript
// Hybrid selector (sync, NOT async)
export const usersAtom = atom((get) => {
  const stream = get(streamAtom);
  return stream !== undefined ? stream.value : get(singleFetchAtom);
});
```
