WordPress is an awesome tool for setting up a blog. With its vast sea of plugins and themes, combined with an API that spans into every corner of the system, you can build nearly any kind of web application with it. This advances it from a content management system to a full-fledged platform for creating web applications.
In this tutorial, you will learn how to make a WordPress plugin that hooks into the API. It will then present a simple, AJAX-ed todo list application on the /todo URL of your WordPress site. The best thing is that this is a plugin and not a theme, which means you can use it on any WordPress site regardless of the theme.
