React JS Setup

The React OneSignal package is a JavaScript module that can be used to easily include OneSignal code in a website or app that uses React for its front-end codebase.

Migration Guide

Version 2.0 was recently released. Read the Migration Guide here if you're coming from a version 1 release of the SDK.

Install

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.

//Example1
await OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });
// do other stuff

//Example2
const [initialized, setInitialized] = useState(false);
OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' }).then(() => {
  setInitialized(true);
  OneSignal.showSlidedownPrompt().then(() => {
    // do other stuff
  });
})

Local host example

When running locally, you can explicitly reference that you are connecting via an HTTP protocol. When configuring your integration in OneSignal, you will also need to set your domain to your local host and turn on local testing.

Create an async function that initializes OneSignal, and calls the showSlidedownPromp funciton.

import OneSignal from 'react-onesignal';

export default async function runOneSignal() {
  await OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx', allowLocalhostAsSecureOrigin: true});
  OneSignal.showSlidedownPrompt();
}

Then you can call this function within your application to capture subscription preference.

import runOneSignal from './onesignal';
import { useEffect } from 'react';

function App() {
  useEffect(() => {
    runOneSignal();
  })

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 Params
You can customize the location and filenames of service worker assets. You are also able to specify the specific scope that your service worker should control. You can read more here.

In this distribution, you can specify the parameters via the following:

FieldDetails
serviceWorkerParamUse to specify the scope, or the path the service worker has control of. Example: { scope: "/js/push/onesignal/" }
serviceWorkerPathThe path to the service worker file.

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).

The OneSignal SDK file must be publicly accessible. You can put them in your top-level root or a subdirectory. However, if you are placing the file not on top-level root make sure to specify the path via the service worker params in the init options (see section above).

Tip:
Visit https://yoursite.com/OneSignalSDKWorker.js in the address bar to make sure the files are being served successfully.

🚧

Service Worker Unregister

Make sure in your codebase, you are not calling the unregister() method. Usually this is in the index.js.

This will unregister the OneSignal Service Workers.

Advanced Usage

Events and Event Listeners

Use listeners to react to OneSignal-related events:

  • subscriptionChange
  • permissionPromptDisplay
  • notificationPermissionChange
  • popoverShown
  • customPromptClick
  • notificationDisplay
  • notificationDismiss
OneSignal.on('subscriptionChange', function(isSubscribed) {
  console.log("The user's subscription state is now:", isSubscribed);
});

See the OneSignal WebSDK Reference for all available event listeners.
