Manual:Hooks/ResourceLoaderGetConfigVars

ResourceLoaderGetConfigVars
Available from version 1.17.0 Called right before ResourceLoaderStartUpModule::getConfig returns, to set static (not request-specific) configuration variables
Define function:	public static function onResourceLoaderGetConfigVars( &$vars ) { ... }
Attach hook:	$wgHooks['ResourceLoaderGetConfigVars'][] = 'MyExtensionHooks::onResourceLoaderGetConfigVars';
Called from:	ResourceLoaderStartUpModule.php

For more information about attaching hooks, see Manual:Hooks.
For examples of extensions using this hook, see Category:ResourceLoaderGetConfigVars extensions.

Details

ResourceLoaderStartUpModule::getConfig() runs this hook. Use it to export static configuration variables to JavaScript. Values that depend on the current page, user or request state must be added through MakeGlobalVariablesScript instead.

• &$vars: Array of variables to be added into the output of the startup module.

Example

Register the configuration variables from the hook:

class VisualEditorHooks {
	public static function onResourceLoaderGetConfigVars( array &$vars ) {
		global $wgVisualEditorDisableForAnons, $wgVisualEditorEnableExperimentalCode;
 
 
		$vars['wgVisualEditor'] = array(
			'disableForAnons' => $wgVisualEditorDisableForAnons,
			'enableExperimentalCode' => $wgVisualEditorEnableExperimentalCode,
		);
 
		return true;
	}
}

Retrieve them using mw.config, like:

conf = mw.config.get( 'wgVisualEditor' );
if ( conf.disableForAnons ) {
	// Do stuff
}
