Follow these steps to get your EUM App Key and instrument your React Native application.


  • React Native >= 0.60

    The React Native Agent has been tested and certified to work with React Native >= 0.60. React Native is in rapid development; thereby any minor update to React Native could potentially affect the functionality of the React Native Agent.

  • (iOS only): Pod target and Xcode deployment target must both be >= 11. Find the pod target version in the podfile located in <your_react_native_app>/ios/.

Get Your Application Key

From the Controller's Getting Started Wizard, create either an iOS or an Android application. You will be given an EUM App Key that you will use to instrument your application. In some cases, multiple mobile applications can share the same key.

If you have completed the Getting Started Wizard, but don't have your EUM App Key, see Get Your Application Key.

Eject Your React Native Application

 If you created your React Native application with one of the commands in the following table, you will need to eject the application:

CommandWhy Ejection Is Needed


This command enables you to quickly set up and run a Native React application with no configuration but does not provide the full development environment required by the React Native Agent.

expo init

Expo projects do not currently support the React Native Agent module. 

If you created your app with create-react-native-app, use npm to eject the app. If you used expo, run the expo command below to eject the app.

From your project directory, run the command appropriate for your use case:

 npm run eject
expo eject

Install the React Native Agent

This module injects the native AppDynamics agents into your application and offers a JavaScript bridge to the Instrumentation management interface.

  1. Install the React Native Agent:

    npm install --save @appdynamics/react-native-agent
  2. Build the configuration to enable the build-time instrumentation of your application:

    node node_modules/@appdynamics/react-native-agent/bin/cli.js install

    The React Native Agent CLI assumes you've kept the default project structure created with the react-native CLI tools.

If the above commands failed, see Manually Install the React Native Package. Otherwise, process to (Android only) Add Permissions

(Only If Required) Manually Install the React Native Package

Most users do not have to manually install the package, but the command above may fail if you heavily modified your iOS and Android projects.

Follow these steps to manually install the React Native package:

  1. Add the following line to your android/build.gradle:

    apply from: '../node_modules/@appdynamics/react-native-agent/android/adeum.gradle'
  2. Make sure the file settings.gradle contains a reference to the Appdynamics agent module as shown below.

    include ':@appdynamics_react-native-agent'
    project(':@appdynamics_react-native-agent').projectDir = new File(rootProject.projectDir, '../node_modules/@appdynamics/react-native-agent/android')
  3. Also, android/app/build.gradle should contain a reference to the Appdynamics agent module.

    dependencies {
        implementation project(':@appdynamics_react-native-agent')
        // ...

For iOS, confirm that the following files exist:

FileFile LocationExample

Libraries or node_modules directory


From Xcode, the file should be listed on the Build Phases > Link Binary With Libraries tab
or in the following directory:<your_react_native_app>/ios/build/<your_react_native_app>/Build/Products/Debug-iphonesimulator/


(Android only) Add Permissions

Add the following permissions to your app's AndroidManifest.xml (which should be located under android/app/src/main/).

  <manifest xmlns:android=""

    // Add the following:
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    // ...

The React Native Agent tries to minimize its network footprint. Without this permission, the agent always assumes poor network conditions and some metrics may not get reported.

Instrument Your Application Code

In the index.js file of your React application:

  1. At the top of the file near the other import statements, add the following line of code to import the Native React Agent:

     import { Instrumentation } from '@appdynamics/react-native-agent';
  2. In the same file and in the global scope, initialize the instrumentation with the following, making sure to replace <EUM_APP_KEY> with a string containing your EUM App Key.

        appKey: <EUM_APP_KEY>,
  3. Verify that your index.js file looks similar to the following:

    import {AppRegistry} from 'react-native';
    import App from './App';
    // === Add the following to import the React Native Agent
    import { Instrumentation } from '@appdynamics/react-native-agent';
    // Initialize the instrumentation
        appKey: 'YOUR-APP-KEY',
    // Create a component
    const App = () => (
      // Other components
    // Register the App component
    AppRegistry.registerComponent('my-application', () => App);


Build and Run Your React Native Applications (Optional) 

  1. Run the command to build and run the app for your platform.

     react-native run-android
    react-native run-ios 
  2. From the Controller UI, verify that the instrumentation was successful.

Point to an On-Premises EUM Server (Optional)

 To use an on-premises EUM Server, pass the URL to the on-premises EUM Server when you initialize the instrumentation with the EUM App Key from Get Your Application Key

     appKey: <EUM_APP_KEY>,
     collectorURL: <COLLECTOR_URL>
