At WordCamp Miami this year, I showed how and why, I use AngularJS for building WordPress plugin admin interfaces. For our A/B Testing plugin Ingot we chose to build our interface in Angular beacuse it was the fastest and best way to build an interface that had to be highly dynamic.
I gave two talks, one on Angular basics, and then the second one dove into my specific use case. With this information & with a knowledge of how to extend the WordPress REST API you should be able to start creating new & exciting WordPress user experiences.
It was awesome to be a part of a day full of developers explaining why they made their choice in framework. I hope this type of sharing will lead people away from “What framework should I use?” to understanding the strengths and weaknesses of each framework and make that decision on a per project basis.
In Ingot, Angular is a thin UI layer on top of what is mainly a PHP codebase. I needed a really solid AJAX interface — sorry jQuery — that would allow the interface to have lots of different UI states easily available. Angular provides that.
I want to add that while the focus of these talks was Angular, building this way, in my opinion, requires an API-first approach to the PHP code. I wrote extensively about this before. The short version is that it requires keeping the code required for reading and writing to the database totally decoupled from the front-end use, and API code.
