We can emulate different operating systems, browsers, and devices within a desktop operating system. We’re going to discuss iOS and Android options we have available to us, and how to debug on those devices.

 

More than often we want to test what we have seen is what user see our app. To do that we need to use device to test our web application.

To enable device testing, the easiest to do it:

Install:

npm install ngrok -D

 

Suppose our application is running on localhost:8000, then we can run the command:

ngrok http 8000

 

Of course this is only one way to test web application on mobile device.

You can also use Remote debuging with Chrome: 

chrome://inspect/#devices

 

To test on difference brwoswers, we can also use.
