dcr_renderer

The DCR Renderer module provides a Twig extension and Single Directory Component (SDC) for fetching and rendering content from Drupal Content Repository URLs or local file paths. It has multiple processing options for proxying urls and assets.

It works hand in hand with the Drupal Content Repository module which makes URLs available for Drupal Entity which can be used to embed the entity in a Single Directory Component (SDC). The Drupal Content Repository it draws from can be on a remote Drupal server or on the same server.

Features

• Twig Extension: dcr_get_contents() function for fetching and processing remote/local content
• SDC Component: dcr-render component for embedding content with fallback options
• Multiple Processing Types: Raw, proxied, hardened, and full processing options
• Asset Extraction: Automatically handles CSS and JavaScript from fetched content
• Security Controls: Domain restrictions, file extension filtering, and content sanitization
• Caching: Configurable caching for improved performance
• Error Handling: Graceful fallbacks when content cannot be fetched
