OneSignal custom button helper

Do you like the default OneSignal bell icon? You don't? Are promptyOptions.customLink options too limiting for you. Build your own subscribe button with onesignal-custom-button-helper.

Installation

Usage

Follow OneSignal documentation to init OneSignal SDK and add OneSignal service worker. Hide default subscribe button provided by OneSignal by setting notifyButton.enable to false.

Javascript (OneSignal SDK initialization)

var OneSignal = window.OneSignal || []
OneSignal.push(function() {
	OneSignal.init({
		appId: 'your-onesignal-app-id',
		notifyButton: {
			enable: false, // Hides OneSignal circular bell button
		},
	})
})

HTML

<button type="button" id="togglePush" style="display: none;"></button>

JavaScript (custom button handler)

import { onesignalCustomButtonHelper } from 'onesignal-custom-button-helper'

const $button = document.querySelector('#togglePush')

const toggle = onesignalCustomButtonHelper((state) => {
	if (state === 'not-supported') {
		// Keep toggle button hidden
		return
	}

	if (state === 'loading') {
		// Prevent user from clicking it
		$button.disabled = true
		$button.innerText = 'Loading…'
	} else {
		// Reenable and show button if not visible
		$button.disabled = false
		$button.style.display = 'inline-block'

		// Update text accordingly
		if (state === 'subscribed') {
			$button.innerText = 'Unsubscribe'
		}
		if (state === 'not-subscribed') {
			$button.innerText = 'Subscribe'
		}
	}
})

// Toggle subscription on button click
$button.addEventListener('click', toggle)
