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

Requirements

OneSignal Account
Your OneSignal App Id, available in Settings > Keys & IDs.

If you have not done so already, you may benefit from following our Web Push Quickstart first.

Vue Compatibility

Make sure you install a plugin version compatible with your Vue environment.

Vue	OneSignal Plugin
2	onesignal-vue
3	onesignal-vue3

Install

Yarn

yarn add onesignal-vue

# or

yarn add @onesignal/onesignal-vue3

npm

npm install --save onesignal-vue

# or

npm install --save @onesignal/onesignal-vue3

Usage

Plugin setup

Vue2

import Vue from 'vue'
import OneSignalVue from 'onesignal-vue'

Vue.use(OneSignalVue);

Initialize OneSignal with your appId via the options parameter:

new Vue({
  render: h => h(App),
  beforeMount() {
    this.$OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });
  }
}).$mount('#app')

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

//Example 1
await this.$OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });
// do other stuff

//Example 2
this.$OneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' }).then(() => {
  // do other stuff
});

Vue3

In Vue 3, you can pass in the OneSignal initialization options directly as an argument to the use function. You can still initialize separately if you prefer editor benefits like code completion.

// main
import { createApp } from 'vue'
import OneSignalVuePlugin from '@onesignal/onesignal-vue3'

createApp(App).use(OneSignalVuePlugin, {
  appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
}).mount('#app');

//main
import { createApp } from 'vue'
import OneSignalVuePlugin from '@onesignal/onesignal-vue3'

createApp(App).use(OneSignalVuePlugin).mount('#app');

// component
this.$OneSignal.init({
  appId: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
});

The OneSignal plugin automatically exposes a $OneSignal global property accessible inside the application.

Composition API

You can also leverage Vue's Composition API via the useOneSignal function that can be called from within setup.

Reference

Code completion

If IntelliSense is not working as expected in your .vue file, try adding an import from the OneSignal plugin.

<script>
import OneSignalVue from 'onesignal-vue';

export default {
  name: 'HelloWorld',
  props: {
    msg: String
  },
  beforeCreate() {
    this.$OneSignal.showSlidedownPrompt()
  }
}
</script>

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 not placing the file on the 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 file is being served successfully.

Advanced Usage

Events and Event Listeners

Use listeners to react to OneSignal-related events:

subscriptionChange
permissionPromptDisplay
notificationPermissionChange
popoverShown
customPromptClick
notificationDisplay
notificationDismiss

this.$OneSignal.on('subscriptionChange', function(isSubscribed) {
  console.log("The user's subscription state is now:", isSubscribed);
});
