How to open a desktop app from Angular application?

Question

I have an Angular App running in my browser (Chrome, IE and Firefox). On Click of a button , it should open a local app, which is a stand alone desktop app, already installed in my system.

First of all, Is it possible? Will Angular / Browser allow such actions?

If possible, which all are the possible ways?

Can somebody help me?

it is restricted by the browser. only some IE hacks can run files on your machine. — Andrei, Mar 10 '20 at 11:28
If your browser allows a page to run an executable from JavaScript then it sounds like you should patch or replace your browser. — David, Mar 10 '20 at 11:30
Do you understand the security risks of a browser that would allow this? — Stultuske, Mar 10 '20 at 11:31

It is possible to do that using protocols, by default browser supports file:// and some other custom protocols that opens up the files in the browser window, applications like slack and discord use custom protocols that are built using electron into the applications and in the machine registry that chrome can trigger to open up an application from the web application.

Yes, it is possible via calling application protocol, registered at the time of installation time in our system.

Example:

You can open postman app installed via snapcraft from the browser

syntax:

postman:///

Note: You should know the registered protocol of the app and the app should not portable

via HTML:

<a href="postman:///">Open Postman</a>
