Using Composer with WordPress Scott Walkinshaw · August 18, 2013
Composer is a dependency manager for PHP that has been gaining steam lately. Your first question is most likely “what is a dependency manager and why do I need one?”. Almost any code you write probably ends up depending on 3rd party libraries. All of these libraries (projects, frameworks, files, etc) become dependencies of your project. Composer lets you declare the dependencies for a project and it will install and manage them.
If there is one issue that virtually all of my clients ask me about within their first 30 days of getting to know WordPress, it’s how to work with images. For all the amazing bells and whistles WordPress provides users, images still continue to be a bit of a sticking point for folks.
