A note on Composer

Composer is a popular way to manage library dependencies in projects. Although PHPDevShell itself or its GUI don’t directly use Composer, your plugins/site may of course rely on it.

However the framework cannot handle that task for you for two reasons:

• the developers of Composer don’t allow it
• each plugin/site may depend on different versions of one library
  

That means each plugin/site is responsible for its own composer.json file, vendor folder, etc.

One of the standard plugins provided with PHPDevShell, named “PHPMailer”, uses Composer to stay up-to-date with the upstream version of PHPMailer.
