How to use pusher.js in service worker

Question

I want to use pusher.js in service worker for sending notification to user when the app(pwa) is closed. But I get below error in pusher.js:

window is not defined

Answer 1

I got the answer, in service worker you can not import pusher as below:

import Pusher from 'pusher-js';

Instead import as below:

importScripts("https://js.pusher.com/7.0/pusher.worker.min.js");

Or

import Pusher from 'pusher-js/worker';
