How to detect platform using Ionic 4

How to get platform information using Ionic 4.

In Ionic 3 , we can do as mentioned below.

    if('android') ||'ios') ||'core'))

But this is not working in Ionic 4. Can anyone please help me how to do this in Ionic 4 or what can be the alternate for this?

Depending on what you want to do:

@Sujan12 How to detect desktop browser platform using this because when I tried with below it is not falling in ‘core’ condition.

      if ('core')) {
        alert('core platform');
      } else {
        alert('something else');

No idea, the link I posted only refers to a is('cordova').

Is there a workaround for this yet?
Detecting ‘core’ or desktop browser in any way other than screen size?

This just got updated yesterday. Looks like ‘core’ is supposed to work. I know it doesn’t now, but maybe in the next update?

I am using

this.isApp = (!document.URL.startsWith(‘http’) || document.URL.startsWith(‘http://localhost:8080’));

So if isApp is true I am running native on Android or IOS else it is in the browser

@btsiders Great, looking forward to it. Thanks for the heads up.
@developergeme Thanks for that too. I’ll try it tomorrow if there is no update.

Desktop is now detected in 4.0.0-beta.4

Your are still using beta.1.

Here is a post with some upgrade instructions;

Note: the current is Beta 5 but the desktop detection came in beta 4.

Thanks for upgrade instructions.

On Ionic 4 Platform is unber ‘@ionic/angular’

import { Platform } from ‘@ionic/angular’;

I did


to get the platform names when I was debugging on my browser. Note that this gives different platform names if you are testing from real android or ios device.

I also did

if('mobileweb')){ .... }

to check if my platform was a browser.

i get the result same :-1:
if (‘desktop’)) {
} else if (‘ios’)) {
} else if (‘android’)) {
// fallback to browser APIs
But default http://localhost:8100/home
show the result ‘android

I tried console.log(platform.platforms()); and tested this statement in different devices, once on browser and once on real device, it did return different platform values available.

i also use second way
But output get on browser

That’s the thing. It outputs different platforms based on the device. So we can’t predict accurately which platform we are actually on.
