Small World is a web appication written entirely by Jordan Smith. The application uses Instagram's API to update users' photos to the site in real time which were added by the use of certain hashtags in their caption. The application follows hastags that are associated with different colleges in America. These photos are generated only by those who have public Instagram acounts.
I'm glad you're here to peak under the hood. You can take a look at the source code of this project on github
This is application was inspired by This Is Now! made by Lexical Gap and lollagram made by Michael Landcaster. Likewise small world was built using Node.js on Express. For communication between the server and the client, Small World uses socket.io which is a powerful node library that uses websockets. Finally to help out with the complication of Instagram's API, the module "instagram-node-lib" was used. On the first run of the node server, the app subscribes to the hashtags for each college. Instagram notifies the app each time there is a new post. The server then polls instagram for the json object of the new post. The connection between the client and the server is then used to send the object to the browser. A great deal of templating is done and the picture is displayed to the client. When the user picks a new feed, the page is wiped and the most recent photos from the new feed are displayed while it listens for new ones to come in.
