Instagram realtime demo

This Node.js application implements a client of Instagram realtime API:

• it receives notifications of new activity in a given geography (in this case, the center of Madrid, Spain),
• and, if the notification is valid, the last photo of the geography is fetched from the traditional API,
• and, if this photo is valid, it is send through a websocket channel named 'photos',
• then, a websocket in the frontend view (index.html) gets the photo and represents it in a map

Each of these two functionalities is performed in the files:

• app.js: which contains the main Node.js application
• index.html: which renders the map and gets notifications through a websocket from the Node.js application
