Use mobile devices to scan QR codes and open Internal URLs.
The app is available at https://darongmean.com/internal-url/app .
Why do you want to use the app?
An Internal URL is a URL that is hosted on a private network.
For example, http://localhost:3000 or http://127.0.0.1:3000.
I usually run a web server on my laptop and open http://localhost:3000 when developing web applications.
Then I want to test the applications on mobile devices.
The issue is it takes more steps than I wanted to open the URL on mobile devices. I might be in the zone, or I am too lazy to switch context.
