Reactive workshop

Today we're building Instagram image scraper.

Instagram has an API to poll for recent media to get media's attributes, including URL and location. Your program will be sending that information to a pre-cooked web UI for display.

Step zero: Necessary evil

Please login into Instagram, go to https://instagram.com/developer/ and create an app (Manage Client > Register a New Client) to obtain Client ID that is required to call Instagram's API. You may put http://rxdisplay.neueda.lv/ into Website and http://rxdisplay.neueda.lv/oauth into OAuth redirect uri. Any other URL-s would do too.
