Developing your first WP Ultimo Add-on


One of the coolest things about WordPress is how forgiving it can be when it comes to development. The amount of customizations you can make by pasting snippets inside a theme’s functions.php file is a testimony to that fact.

Things change a little when you need to develop production-grade software on-top of WordPress – or WP Ultimo, for that matter. Other factors such as performance, following best-practices, readability all come into play.

The goal of this course is to teach you how to get started with add-on development for WP Ultimo and to share what we’ve learn in the past 5 years of maintaining such a huge project.

We’ll go over some of the internal tools we use – and that we’ve open-sourced – to save time and guarantee code quality, such as our add-on boilerplate generator and MPB – our internal task runner, responsible for minifying files, formatting code, generating the final .zip, among other things.
