How To Use Amplitude With React Native
Integrating Amplitude into your React Native application is relatively straightforward and can unlock valuable insights. Here are the steps to follow:
Setting Up Your React Native Project
Before integrating Amplitude into your mobile app, you need a React Native project. If you are beginning a new project, first set up the development environment. Install:
- Node.js
- React Native command-line interface (CLI)
- A JDK
- Android Studio (for Android development) or Xcode (for iOS)
Then open a terminal and run this command:
Replace the ‘ProjectName’ with the desired name of your app. If you are going to integrate Amplitude into an existing project, make sure to:
- Run the latest React Native version
- Resolve any outstanding dependencies
- Clean the build folders
Once your React Native project is in good shape, you’re ready to add Amplitude.
Installing Amplitude SDK
Integrating Amplitude into your React Native project requires adding the Amplitude SDK, which lets your app communicate with Amplitude’s services. Here’s how:
Using npm
If you prefer to use npm (Node Package Manager), you can install the Amplitude SDK with the following command:
You will also need to install the async storage for the SDK to work properly. That can be done with this command:
For iOS development, you’ll also need to install the native modules:
Using yarn or expo
Alternatively, if you’re using yarn or expo as your package manager, you can install the SDK with these commands:
These commands will add the Amplitude SDK to your project’s ‘node_modules’ directory and update the ‘package.json’ file to include the dependency.
Initializing Amplitude with React Native
Once the Amplitude SDK is installed in your React Native project, the next step is to initialize it with your unique Amplitude API key. This key connects events tracked from your app to the correct Amplitude project.
Locating Your Amplitude API Key
You can find your API key in the Amplitude dashboard.
- Log into your Amplitude account.
- Navigate to the settings page by clicking the gear icon in the top-right corner.
- Click ‘Organization Settings’ then ‘Projects’ and select the project you want to integrate.
- Open the ‘General’ tab with the API key marked.
Only admins and managers will see the API key, so ensure you have the right permissions.
Adding the Initializing Code
You'll typically want to initialize Amplitude as soon as your app starts up. You can also pass a user ID and config object during this call. Here are three examples:
Remember to replace “API_KEY” with the actual key you obtained from the Amplitude dashboard. Keep it secure and avoid committing it directly to your version control system.
Event Tracking in Amplitude with React Native
With Amplitude initialized in your React Native application, you can now begin to track events. Events are the core of Amplitude’s analytics and represent any action a user might perform.
This could be anything from opening the app, clicking a button, completing a level, or making a purchase.
To track an event, you’ll use the instance of Amplitude you set up and code like this:
Make sure that the string you use to identify the event (‘Button Clicked’ in this case) is descriptive enough to make sense when analyzing the data later. Keeping consistent naming conventions is crucial for interpreting your event data accurately.
Tracking User Properties Using React Native
Sometimes, events themselves don’t tell the whole story and need additional context to be useful. Amplitude allows you to add extra data points, known as user properties, to give more detail into the circumstances under which an event was triggered.
The ‘Identify’ object is used to control user properties, and the SDK supports the operations:
- set
- set0nce
- unset
- add
- append
- prepend
- preInsert
- postInsert
- remove
An example of tracking user properties might look something like this:
You can chain multiple operations into a single object, which is then passed to the Amplitude client.
Analyzing Data in Amplitude
Tracking data isn’t very useful without thorough analysis. The Amplitude dashboard can be set up to display your most-used metrics or dig into granular details about your user base.
On the dashboard, you can create charts for:
- User and event segments
- Conversion funnels
- Retention metrics
- User journeys
Or a more comprehensive data table that compares and breaks down multiple metrics. Create user personas, view the stickiness of new features, or get a high-level revenue breakdown for long-term planning.
There are also templates available for several different use cases:
- Funnel analysis: Used to understand drop-off points
- Feature adoption: Measuring the impact of a feature on various metrics.
- Product KPIs: Overall health of your product.
- Session engagement: A detailed look at how users interact with your app.
- Marketing analytics: Reports on bounce rates, conversion paths, and web traffic.
- User activity: View active and unique user rates to see product and feature adoption.
Regularly reviewing and acting upon the data is key to maintaining a user-centric approach and fostering a successful app lifecycle.
Troubleshooting Common Issues with Amplitude and React Native
While Amplitude is designed to be as straightforward as possible to integrate with React Native, developers may occasionally encounter issues. Here's how to troubleshoot some of the most common problems you might face during the setup and use of Amplitude in your React Native project.
SDK Does Not Install Properly
Run npm install @amplitude/analytics-react-native again to ensure all files were installed correctly. Check your internet connection, as disruptions can sometimes cause package installation to fail.
Native Dependencies Don’t Link Automatically
For React Native versions prior to 0.60, manually link the Amplitude SDK by running this command line:
Make sure to rebuild your project after manually linking dependencies.
Missing API Key Error
Ensure you have correctly placed your Amplitude API Key in the initialization code. Verify there are no typos in your API Key and that it is current by refreshing your Amplitude dashboard.
Amplitude Instance Not Recognized
Check if the Amplitude SDK import statement is correct and if the package name matches the one in your ‘node_modules’ folder. Ensure you’ve created the Amplitude instance and called the .init() method at the top level of your app.
User Properties Not Associating Properly
Ensure you are using the correct ‘Identify’ instance methods (set, add, etc) to define user properties. Double-check that the user properties are being sent before or together with corresponding events.
Slowdowns or Crashes after SDK Integration
Profile your app’s performance to identify any bottlenecks. React Native’s own profiling tools or Chrome’s DevTools can be helpful. Look for any loops or excessive event tracking causing performance degradation.
Final Thoughts
Amplitude can empower your React Native apps with robust analytics capabilities, providing deep insights into user behavior and app performance. Follow the steps above to integrate the two and lay the groundwork for a data-driven approach to user engagement and product growth.
Remember, the power of Amplitude isn’t just in measuring what users do but in helping you understand why they do it.
