Add-on dependencies#

Sometimes your addon depends on another addon. You can declare addon dependency in your addon's addons key, just like you do in your project. By doing so, that other addon's configuration loader is executed first, so you can depend on the configuration being already applied. Another benefit is that you'll have to declare only the "top level" addon in your project, the dependencies will be discovered and automatically treated as Volto addons. For example, volto-slate depends on volto-object-widget's configuration being already applied, so volto-slate can declare in its package.json:

{
  "name": "volto-slate",
  ...
  "addons": ['@eeacms/volto-object-widget']
}

And of course, the dependency addon can depend, on its turn, on other addons which will be loaded as well. Circular dependencies should be avoided.
