Expo

Sentry's React Native SDK works out of the box with Expo applications. To see readable stack traces in the product, you must upload source maps to Sentry. This guide explains how to upload source maps for Expo applications.

Prerequisities

• Sign up for an account
• Migrate from sentry-expo to @sentry/react-native
• Set up Sentry React Native SDK version 5.16.0-alpha.4 or newer

Common Setup

To upload source maps, the Sentry Expo Plugin and the Sentry Metro Plugin need to be added to the Expo application.

Add the Sentry Expo Plugin

To ensure bundles and source maps are automatically uploaded during the local and EAS native applications builds, add the @sentry/react-native/expo config plugin to the Expo application configuration:

{
  "expo": {
    "plugins": [
      [
        "@sentry/react-native/expo",
        {
          "url": "https://sentry.io/",
          "note": "Use SENTRY_AUTH_TOKEN env to authenticate with Sentry.",
          "project": "example-project",
          "organization": "example-org"
        }
      ]
    ]
  }
}

Add auth token to your environment:

# DO NOT COMMIT YOUR AUTH TOKEN
export SENTRY_AUTH_TOKEN=sntrys_YOUR_TOKEN_HERE

Add the Sentry Metro Plugin

To ensure unique Debug IDs are assigned to the generated bundles and source maps, add the Sentry Metro Plugin to the configuration:

// const { getDefaultConfig } = require("expo/metro-config");
const { getSentryExpoConfig } = require("@sentry/react-native/metro");

// const config = getDefaultConfig(__dirname);
const config = getSentryExpoConfig(__dirname);

module.exports = config;

Automatic Upload for Release

When the Sentry Expo Plugin @sentry/react-native/expo and the Sentry Metro Pugin are added to your application configuration, source maps for the native builds are uploaded automatically during EAS Builds and when building the native application release locally using npx expo prebuild.

Manual Upload for EAS Updates

To upload source maps for EAS Updates and npx expo export, set up the Sentry Expo Plugin, the Sentry Metro plugin and execute the sentry-expo-upload-sourcemaps command.

Create Update

To create an update for the application use the following command:

# npx expo export --dump-sourcemap
eas update

Upload Source Maps

To upload source maps for all platforms use the following command:

SENTRY_PROJECT=example-project \
SENTRY_ORG=example-org \
SENTRY_AUTH_TOKEN=sntrys_YOUR_TOKEN_HERE \
npx sentry-expo-upload-sourcemaps dist

Notes

• dist is the default output directory of eas update.
• Uploaded source maps have no associated releases. This is expected as updates can apply to multiple releases.

Notes
