Rails ActionCable

By Emiliano Coppo

DevSnack #40: Everything changes. It’s a fact. A few years ago web development was very rudimentary, it just comprehended to serve a bunch of files from a web server which then the browser would interpret and render as a web page. But as time goes on, new technologies and also new requirements have emerged, transforming web pages from their ‘static’ origins to very rich, interactive, real-time complex applications. With Rails 5, ActionCable promises to help developers to include these real-time features seamlessly into any Rails app. Let’s learn about it and discover all the cool things we can do with it!
