Expo

To set up the Sentry React Native SDK in your Expo project, follow the steps on this page.

Prerequisities

• Expo SDK 50 or newer.
  • Expo SDK 49 and older are supported by the sentry-expo package.
• Migrate from sentry-expo to @sentry/react-native.
• Sign up for an account.

Install the Sentry SDK

Install the @sentry/react-native package:

npx expo install @sentry/react-native

Intialize the SDK

Import the @sentry/react-native package and call init with your DSN:

import { Text, View } from "react-native";
import * as Sentry from "@sentry/react-native";

Sentry.init({
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",

  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,
});

function App() {
  return (
    <View>
      <Text>Expo Example!</Text>
    </View>
  );
}

export default Sentry.wrap(App);

Wrap Your App

Wrap the root component of your application with Sentry.wrap:

export default Sentry.wrap(App);

Add the Sentry Expo Plugin

To ensure bundles and source maps are automatically uploaded during the native applications builds, add withSentry 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 Sentry Metro Plugin

To ensure unique Debug IDs get assigned to the generated bundles and source maps, add Sentry Serializer to the Metro 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;

Add Privacy Manifest

The SDK needs access to certain information about the device and the application for its essential functionality. Some of the APIs required for this are considered privacy-relevant. Add the privacy manifest to your Xcode project to ensure your app is compliant with Apple's guidelines. Read the Apple Privacy Manifest guide for more info on how to add records required for the Sentry SDKs.

Verify Setup

To verify that everything is working as expected, build the Release version of your application and send a test event to Sentry by adding:

<Button
  title="Try!"
  onPress={() => {
    Sentry.captureException(new Error("First error"));
  }}
/>;

• Add automatic performance monitoring with Expo Router

Notes

• Don't commit your auth token. Instead, use an environment variable like SENTRY_AUTH_TOKEN.
• Source maps for the Release version of your application are uploaded automatically during the native application build.
• During development, the source code is resolved using the Metro Server and source maps aren't used. This currently doesn't work on web.
