Is your feature request related to a problem? Please describe.
I would like to have a JS function (util?) or a gloval variable that lets me know if we are in edit mode. Sometimes we do things differently in edit mode. For instance, maybe a login form needs to auto redirect if already logged in. This is hard to edit/debug if it is always redirecting. I would like to do something like (if (!editMode) redirectToNewURL

Describe the solution you'd like
Either a function in utils or a global variable

Describe alternatives you've considered
Parse the URL. This is hacky and is impossible to make a global JS function to do this as the url object is not available at the global level.
