# @sentry/expo-upload-sourcemaps
Command-line tool for uploading JavaScript bundles and source maps from Expo builds to Sentry, so that production error stack traces are symbolicated back to original source.
## Usage
```bash
SENTRY_AUTH_TOKEN= \
npx @sentry/expo-upload-sourcemaps dist
```
`dist` is the output directory produced by `npx expo export` or `eas update`.
## Environment variables
| Variable | Required | Description |
|---|---|---|
| `SENTRY_AUTH_TOKEN` | yes | Sentry auth token with `project:write` scope. |
| `SENTRY_ORG` | when no Expo plugin config is present | Sentry organization slug. Falls back to the `@sentry/react-native/expo` plugin config in `app.json` / `app.config.ts`, or the `defaults.org` entry in `android/sentry.properties` / `ios/sentry.properties`. |
| `SENTRY_PROJECT` | when no Expo plugin config is present | Sentry project slug. Same fallback order as above. |
| `SENTRY_URL` | optional | Sentry instance URL. Defaults to `https://sentry.io/`. |
| `SENTRY_CLI_EXECUTABLE` | optional | Path override for the `sentry-cli` binary. |
Environment variables are also read from `.env.sentry-build-plugin` at the project root.
## Relation to `@sentry/react-native`
The same CLI is re-exposed inside `@sentry/react-native` under the bin name `sentry-expo-upload-sourcemaps`. Projects that already have `@sentry/react-native` installed can invoke either form:
```bash
npx @sentry/expo-upload-sourcemaps dist
# or
npx sentry-expo-upload-sourcemaps dist
```
The new scoped form is preferred for new setups.
