Building Data-Driven Web Applications with WordPress (WordPress App Design part 3)

In the last post in this series, we built a REST interface to our server data, which consists of Events and Venues. The REST interface provides the functionality to perform all the necessary CRUD (Create, Read, Update and Delete) operations from a client (e.g. a browser or Curl from a command line) and makes use of WordPress roles and capabilities to determine whether the user making the request has the necessary permissions to perform the requested operation.

Our goal in this post is to create a well-structured data-driven Web Application embedded in a WordPress page that makes use of good modern design patterns and leverages the REST interface we built in the previous tutorial. Continue reading

The list will obviously change as new libaries are developed and old ones go by the wayside.  I’m sure I’ve missed off a few as well and so I apologize in advance.  Let me know and I’ll update as I can.  I will try to keep this up to date, but you know how these things go…
