Keep 🐛🐜🐞 out of your app

Bugs can be really cool, but not when it comes to your app.

That's where sentry-expo comes in! Keep a close eye on your app, whether it's in development, staging, or production, by getting real-time insight into errors and bugs. That way, you can quickly reproduce, fix, and re-deploy!

🤔 How do I use this?

Hey- before you actually use Sentry, make sure you've created a Sentry project. How do you do that? Open this drop-down to find out!
🚨 Creating a Sentry project

Before getting real-time updates on errors and making your app generally incredible, you'll need to follow these steps:

  1. Sign up for Sentry (it's free), and create a project in your Dashboard. Take note of your organization name, and project name.
  2. Take note of your DSN, you'll need it later
  3. Go to the Sentry API section, and create an auth token (Ensure you have project:write selected under scopes). Save this, too.

Once you have each of these: organization name, project name, DSN, and auth token, you're all set!

Step 1: Installation

In your project directory, run

expo install sentry-expo

sentry-expo requires some additional dependencies, so you should also run

expo install expo-application expo-constants expo-device expo-updates @sentry/react-native

If you don't have expo-cli installed, you should! But you can also just install with yarn or npm.

Step 2: Code

Add the following to your app's main file (usually App.js):

import * as Sentry from 'sentry-expo';

Sentry.init({
  dsn: 'YOUR DSN HERE',
  enableInExpoDevelopment: true,
  debug: true, // If `true`, Sentry will try to print out useful debugging information if something goes wrong with sending the event. Set it to `false` in production
});

// Access any @sentry/react-native exports via:
Sentry.Native.*

// Access any @sentry/browser exports via:
Sentry.Browser.*

Step 3: App Config

Configure your postPublish hook

Add expo.hooks to your project's app.json (or app.config) file:

{
  "expo": {
    // ... your existing configuration
    "hooks": {
      "postPublish": [
        {
          "file": "sentry-expo/upload-sourcemaps",
          "config": {
            "organization": "your sentry organization slug here",
            "project": "your sentry project name here",
            "authToken": "your auth token here"
          }
        }
      ]
    }
  }
}

Add the Config Plugin

Note: Disregard the following if you're using the classic build system (expo build:[android|ios]).

Add expo.plugins to your project's app.json (or app.config) file:

{
  "expo": {
    // ... your existing configuration
    "plugins": ["sentry-expo"]
  }
}

If you directly edit your native ios/ and android/ directories (i.e. you have ejected your project, or have a bare workflow project), you should instead use yarn sentry-wizard -i reactNative -p ios android to configure your native projects.

"No publish builds"

Note: Disregard the following if you're using the classic build system (expo build:[android|ios]).

With expo-updates, release builds of both iOS and Android apps will create and embed a new update from your JavaScript source at build-time. This new update will not be published automatically and will exist only in the binary with which it was bundled. Since it isn't published, the sourcemaps aren't uploaded in the usual way like they are when you run expo publish (actually, we are relying on Sentry's native scripts to handle that). Because of this you have some extra things to be aware of:

  • Your release will automatically be set to Sentry's expected value- ${bundleIdentifier}@${version}+${buildNumber} (iOS) or ${androidPackage}@${version}+${versionCode} (Android).
  • Your dist will automatically be set to Sentry's expected value- ${buildNumber} (iOS) or ${versionCode} (Android).
  • The configuration for build time sourcemaps comes from the ios/sentry.properties and android/sentry.properties files. For more information, refer to Sentry's documentation. If you're using the managed workflow, then we handle setting these values for your via the plugin you added above.

Please note that configuration for expo publish and expo export in bare and managed is still done via app.json.

Skipping or misconfiguring either of these will result in sourcemaps not working, and thus you won't see proper stacktraces in your errors.

Self-hosting OTA?

If you're self-hosting your Over the Air Updates (this means you run expo export instead of expo publish), you need to:

  • replace hooks.postPublish in your app.json file with hooks.postExport (everything else stays the same)
  • add the RewriteFrames integration to your Sentry.init call like so:
Sentry.init({
  dsn: SENTRY_DSN,
  enableInExpoDevelopment: true,
  integrations: [
    new RewriteFrames({
      iteratee: (frame) => {
        if (frame.filename) {
          // the values depend on what names you give the bundle files you are uploading to Sentry
          frame.filename =
            Platform.OS === 'android' ? 'app:///index.android.bundle' : 'app:///main.jsbundle';
        }
        return frame;
      },
    }),
  ],
});
