TYPO3: How could I add css and js files via controller initialize action and page renderer?

Question

I am using the new page renderer from TYPO3 8 on controller level to add extension specific css and js files via an initializeAction:

public function initial         


        

Answer 1

Notice that there is a different approach available in TYPO3 v8 using the HeaderAssets and FooterAssets sections in your template. Thus your action template could look like this:

Your template code

<f:section name="FooterAssets">
  <link rel="stylesheet" href="{f:uri.resource(path: 'Css/ext_booking_manager.css')}"/>
  <script src="{f:uri.resource(path: 'Js/ext_booking_manager.min.js')}"></script>
</f:section>

This way you don't need any resource logic in your controller, thus your initializeAction() method can be dropped.

BTW: I'd recommend using JavaScript as directory name for JavaScript resources to stay in line with TYPO3 conventions.

Answer 2

In TYPO3 8 getPageRenderer() Method is Deprecated. You can see here Deprecated Methods.

Now you can use this methods in TYPO3 8 Like this solution
