This chapter is from the book


In this hour, you answered a fundamental question about human nature using Node.js, Twitter, and Socket.IO. Not bad for an hour’s work! At the time of writing, there is more love in the world, so if you take nothing else from this hour, rejoice! You learned how a Node.js server can receive large amounts of data from a third-party service and push it out to the browser in real-time using Socket.IO. You saw how to manipulate the data to extract meaning from it and performed simple calculations on the data to extract percentage values. Finally, you added some client-side JavaScript to receive the data and create a real-time graph. This hour showcased many of the strengths of Node.js, including the ease that data can be sent between the server and browser, the ability to process large amounts of data, and the strong support for networking.
