Console output viewer for Office.js add-ins
Fergus McDowall commented
Vorlon and f12 sort of kind of work, but they are a bit of a fiddle, and dont catch fatal errors (bugs that kill an app), and therefore can't be used to fix the worst bugs.
Ideally all Add-ins should run in edge, and the developer should have access to the developer console.

Thanks, Sameera. However, at first glance, I see that Vorlon needs some non-trivial setup as well as a change to the target add-in. This seems fairly intrusive. So, I still hope to see the suggestion above implemented at some point.
If console output is what you are after, you can use Vorlon.js as described at https://github.com/OfficeDev/office-js-docs/blob/master/docs/testing/debug-office-add-ins-on-ipad-and-mac.md
