# Expo + React Native

> Feature-driven Expo app with useInject, memory storage, and RN error rendering.

Same feature-driven layout as the Vite example. Entry at `index.js` → `src/providers/root`.

**Source:** [examples/expo](https://github.com/brushysuite/brushy-librarys/tree/main/examples/expo) · [README.md](https://github.com/brushysuite/brushy-librarys/blob/main/examples/expo/README.md)

## What it demonstrates

* `useInject` and `useStorage` in React Native
* Memory-backed storage (no local persist)
* Custom React Native error renderer via component injection

## Run

From the repository root, build libraries first:

```bash theme={null}
npm run build-packages
```

Then from `examples/expo`:

```bash theme={null}
npm start
```

This clears the Metro cache and sets `EXPO_NO_METRO_WORKSPACE_ROOT=1`.

Or use the root shortcut:

```bash theme={null}
npm run example:expo
```

Requires **Expo Go SDK 57** (matches `expo` \~57 in `package.json`). If you see an SDK mismatch:

1. Stop every Metro process (`Ctrl+C`, or `lsof -i :8081`).
2. Run `npm start` again from `examples/expo`.
3. In Expo Go, remove the old project from **Recently opened** and scan the new QR code.

<Note>
  The Expo dev server is not run in CI. Validate locally with `npx expo start`.
</Note>

## Layout

```text theme={null}
index.js
src/
  container.ts
  screens/App.tsx
  features/users/
  shared/logger/
  providers/
```
