Is there a way in angular to know from where is my application been opened? I mean if my application is opened from another tab or window, how can I get the URL of window from where is doing the call? thanks
When a window/tab is opened from a different window/tab, you can access the address of opener using following js:
window.opener.location
The prerequisite to use that is that the link that opened the window has rel="opener" attribute, since modern browsers don't allow access to opener by default.
If the other app is also yours, add some "place_id" to the URL to open your app. Different "place_id" from different places. And analyze it in the app via "window.location" or via router parameters.
