Install

You can use yarn or npm.

Yarn

yarn add react-onesignal

npm

npm install --save react-onesignal

---

Usage

Initialize OneSignal with your appId via the options parameter:

import OneSignal from 'react-onesignal';

OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });

The init function returns a promise that resolves when OneSignal is loaded.

Examples

await OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });
// do other stuff

---

const [initialized, setInitialized] = useState(false);
OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' }).then(() => {
  setInitialized(true);
  OneSignal.Slidedown.promptPush();
  // do other stuff
})

Init Options

You can pass other options to the init function. Use these options to configure personalized prompt options, auto-resubscribe, and more.

Service Worker File

If you haven't done so already, you will need to add the OneSignal Service Worker file to your site (learn more).

window.OneSignal already defined as 'object'!

You will get this error if you initialize twice. Make sure you are only initializing one time. When wrapped with React.StrictMode, your app might be rendering twice.

Example App

This repo includes an example React application implementing OneSignal. It was created using create-react-app. The app uses this repository's root level directory as the react-onesignal package and will bundle any changes on every run.
