Abstract
The web is no longer about retrieving documents interlinked to each other, as it was envisioned decades ago. With the explosion of the Web 2.0, AJAX led the way towards efficient communication and just retrieving or sending what was necessary. HTML5 introduces a new range of APIs that make the creation of full-fledged interactive applications easier than ever. With that comes WebSocket, which exposes a very basic channel of bi-directional communication with little overhead. WebSocket enables the transmission of data in real time faster and easier than ever before. Projects like Socket.IO, subject of this talk, have been working hard on bringing this API to everyone, in the same way jQuery did for the DOM and AJAX. Not only do we make WebSocket ready for real-world usage, but it comes with fallbacks for every browser. This talk will explore the creation and deployment of a realtime application the audience can interact with from their laptops and mobile devices.
