Push Notifications In React With OneSignal

It’s no secret that push notifications can help you engage and retain app users. In this tutorial, we'll show you how to integrate with the React-OneSignal NPM package to leverage push notifications in your React app.

Install OneSignal NPM package

Inside of your project folder, open your terminal and run the following command to install the React OneSignal NPM package.

npm i react-onesignal

Import OneSignal NPM

After you have successfully installed the npm package, open your App.js file, you will enter the following line of code at the top of the file:

import OneSignal from 'react-onesignal';

Use OneSignal NPM

The code above will make the OneSignal object accessible and will allow you to have access to the OneSignal SDK properties. In the same file, we will create a useEffect hook. This hook will have the initialization code needed to trigger OneSignal. Remember to add the dependency array [] to your useEffect hook. The init() method from OneSignal can only be called once and the dependency array will help us to avoid that the useEffect gets triggered multiple times firing the init() method.

useEffect(() => {
   OneSignal.init({
     appId: "YOUR-APP-ID-HERE"
   });
 }, []);
