swPushListener.js

self.addEventListener("push", event => {
  const data = event.data.json()
  const { title } = data

  const body = {
    body: data.body,
    icon: data.icon
  }

  event.waitUntil(self.registration.showNotification(title, body))
})

Hey Jasmina ! I liked your article about using webpush notifications I am just wondering

Where would I add this ?
"self" refers to what in this context

@bidorboocrew This is exactly the question I have, too. Did you find out where to add this?

you add it to your service worker file in your react code
