ngx-electron | A simple Angular wrapper for electron 's Renderer API

Ok so basically to answer in a bit more detail:

Electrun is a multi process architecture. Basically, there are 2 processes, the main processes which is a nodeJS process and the renderer process which is a BrowserWindow running chromium. https://www.electronjs.org/docs/tutorial/application-architecture#differences-between-main-process-and-renderer-process

Angular runs in the renderer. Since that is basically browser environment you can only perform javascript code that also works in a normal browser context. In a browser you can not perform scripts that directly open an application on your PC or something like a shell script. That would be a security nightmare (imagine visiting a website which could then execute arbitrary scripts on your PC. they could just run rm -rf / or open like e.g. 1000 instances of word.exe). You can indirectly open some apps with mailto: or tel: links etc...

Since the main process is running nodeJS, you can include standard nodeJS libraries like child_process https://nodejs.org/api/child_process.html.

So to get stuff working for you:

In your code, you should forward the request to open the external application from the renderer (angular) process to the main (nodeJS) process. Checkout https://www.electronjs.org/docs/api/ipc-main and https://www.electronjs.org/docs/api/ipc-renderer on how to do that specifically.
