For almost a year, WordPress has had a REST API. The gradual merge began with WordPress 4.4, released on 8 December 2015. This development makes it easier than ever before for developers working on mobile devices, gaming consoles and many other platforms to work with WordPress websites.
It also makes it much easier for web developers to work with WordPress in all-new ways, such as building themes that use new technologies via JavaScript.
This talk is an introduction to what the REST API is, how it works, and how you can start working with it today in your plugins and themes.
