Because an Arc plugin exists in the multi-tenanted environment of WordPress plugins we must avoid most of Laravel's global helpers to avoid collisions. For this reason the Plugin class of your plugin includes many nifty helper methods which are based on Laravel's own global helpers.
Returns the base URL of the Wordpress instance which is running the Arc plugin. For example:
// Returns "http://mywebsite.com"
\MyCompany\MyPluginName\Plugin::plugin()->baseUrl();
Returns the file path of the plugin's resources directory. For example:
// Returns "/var/www/localhost/wp-content/plugins/my-plugin-name/resources"
\MyCompany\MyPluginName\Plugin::plugin()->resourcePath();
