Twig Pre-Render

Twig Pre-render is a twig extension that allows you to pre-render and preprocess Drupal render arrays so you can get at all the contextual variables inside.

This is handy if you're trying to map Drupal elements to Drupal-independent Twig components. Have a paragraph that's supposed to be 1:1 with a component built by a non-Drupal developer? Just include the component twig into 'paragraph--myparagraph.html.twig' and call pre_render(field_myfield) to get access to all the variables inside of your field. Also includes a handy Image Attribute function that handles cleanly pulling variables from an image field.

You'll probably also want to use Component Libraries.

Things it currently does not do:

• Access checks
• Care about permissions
• Promise to emulate core in any way

But beyond that we've found it thoroughly useful in building component-based sites, especially if you use tools like KSS-Node and Pattern Lab.

If at some point core allows the ThemeManager::render() call to be split up, we'll probably want to refactor this module.
