@nolanx/svelte-onesignal

The package cloned from react-onesignal and modified to work with svelte.

Welcome to svelte-onesignal 👋

This 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.

• 🏠 Homepage
• 🖤 npm

OneSignal is the world's leader for Mobile Push Notifications, Web Push, and In-App Messaging. It is trusted by 800k businesses to send 5 billion Push Notifications per day.

You can find more information on OneSignal here.

Migration Guide

Install

You can use yarn or npm.

Yarn

yarn add @nolanx/svelte-onesignal

npm

npm install --save @nolanx/svelte-onesignal

---

Usage

Initialize OneSignal with your appId via the options parameter:

import OneSignal from '@nolanx/svelte-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

---

let initialized = false
OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' }).then(() => {
  initialized = true
  OneSignal.showSlidedownPrompt().then(() => {
    // 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 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:

Field	Details
serviceWorkerParam	Use to specify the scope, or the path the service worker has control of. Example: { scope: "/js/push/onesignal/" }
serviceWorkerPath	The 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.

OneSignal API

See the official OneSignal WebSDK reference for information on all available SDK functions.

Advanced Usage

Events and Event Listeners

Use listeners to react to OneSignal-related events:

• subscriptionChange
• permissionPromptDisplay
• notificationPermissionChange
• popoverShown
• customPromptClick
• notificationDisplay
• notificationDismiss

Example

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.

Troubleshooting

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.
