Cant find variable firebase react native

Q: Cant find variable Idbindex Firebase react native?

Its because you have enabled Google Analytics for your app. Disable Analytics from the Firebase settings and again copy the Firebase file data from Firebase and replace it with the old firebase.

I’ve been working with Firebase Cloud Messaging for the last couple of months and it has been a pure pleasure! I always enjoy using Firebase, since I find it so user-friendly combined with great documentation.

Does Firebase work with react native?

But something went completely wrong.

Since I’ve been during all the development on my MacBook and even made the messaging look great on phone using inspect mode, it was ready for launching.

After it went out on the staging URL, I tested it on an android tablet. It looked just the way it should.

But then I took my iPhone… And got a blank page.

Why? What? But how? What is happening?

First in Safari, then I opened with Chrome - still blank.

Since this was running just fine in inspect mode on the laptop, I was really curious about what went wrong. So I connected with USB and opened Safari console from iPhone. And saw this error message.

ReferenceError: Can't find variable: Notification

Of course, I went straight to Google. How could this be, when it works on every other device I’ve tested on.

It didn’t take long before I found this documentation, telling me that iOS Safari is not supported using Firebase Cloud Messaging

See supported environments here: https://firebase.google.com/docs/web/environments-js-sdk

Well, this was of course terrible news. But I was lucky, because most users of this internal web application, are using a laptop.

But it happens rarely, that users are visiting the website on iPhone and we want to prevent blank page - well aware that Cloud Messaging is not an option.

To solve this, I need to figure out if it was iOS or not. I did this with these few lines of code

function isIOS() {
  const browserInfo = navigator.userAgent.toLowerCase();    if (browserInfo.match('iphone') || browserInfo.match('ipad')) {
    return true;
  }  if (['iPad Simulator', 'iPhone Simulator', 'iPod Simulator', 'iPad', 'iPhone', 'iPod'].includes(navigator.platform)) {
    return true;
  }   return false;
}

I use this function, every time I need to use the Notification variable.

Let’s say I need to check if Notification permission is granted

function isGranted() {
  if (isIOS()) return;  return Notification.permission === "granted"
}

And you will avoid your app crashing.
