Check if the user is connected to the internet

Question

I need to know if the user is connected to the internet, and if not, I need to show a screen, but my case is that I created an app from a responsive site that I have, in my app has no file, only the config.xml pointing to the site, when installing the plugin, I have no way to call because the app has nothing, all the files are on the server, it is possible to install the plugin on the server?

Answer 1

You can check the connection via the command Navigator.

Example taken from MDN Web Docs website

if (navigator.onLine) {
  console.log('online');
} else {
  console.log('offline');
}

Another example via Event listeners allows you to manipulate the connection status as you change:

window.addEventListener('offline', function(e) { console.log('offline'); });

window.addEventListener('online', function(e) { console.log('online'); });
