* ViewHelper to add JavaScript modules to the TYPO3 AssetCollector.

|
|
* Examples
|
|
* ========
|
|
*
|
|
* ::
|
|
*
|
|
* <f:asset.module identifier="@my/package/filename.js"/>
|
|
*
|
|
* Details
|
|
* =======
|
|
*
|
|
* In the AssetCollector, the "identifier" attribute is used as a unique identifier. Thus, if modules are added multiple
|
|
* times using the same module identifier, the asset will only be served once.
