title: How to make your own push notification service for your website
body: <p>I am working on a website, where I want to make a feature of notifications, when a user visits my website, they are asked for notifications permission and when they allow it, they will get notifications from my website, and whatever product I want them to get notified by.</p>
  
  <p>Like for example when I visit some websites, they ask me for notifications permissions and when I allow the, I get notified through notifications then. That's all I want for now.</p>
  
  <p>How can I achieve this functionality, I have follow <a href="https://thecodebarbarian.com/sending-web-push-notifications-from-node-js.html" rel="nofollow noreferrer">this</a> tutorial, but still confused how the users who allowed the notifications get detected and how all of them are notified then ? </p>
