Open URL with custom protocol

[samanthal22031410]

I'm developing an extension that communicates with a separate app that the user is expected to have installed and running. This app has registered a custom URL protocol, like foo:// which opens the app. When this URL is entered from the browser, it correctly opens up the app. However, I'd like to also have a button in my extension that will open the app using that protocol. Using cep.util.openURLInDefaultBrowser will not work, because that function requires that the URL have either the HTTP or HTTPS protocols. I've tried using the npm open package, but that does not appear to do anything (totally possible I'm doing something wrong there). Is there a way to accomplish this?

I don't think CEP supports that.

In case anybody else is looking for this answer in the future, open does work, I just had a typo in my protocol 🤦‍:female_sign:

Confirming: Your custom protocol handler works?

Correct - not using CEP, but using the open npm module.
