Drupal 8's render pipeline

published on November 7, 2014

In Drupal 8, we’ve significantly improved the way pages are rendered. This talk explains the entire render pipeline, in some detail. But it also covers:

  • render caching — blocks and entities are now render cached automatically!
  • cache tags — finally we have the cache invalidation system we’ve always needed!
  • assets — only the necessary assets are loaded anymore, thanks to asset dependencies!
  • bubbling — rather than relying on global statics that broke caching, we now correctly bubble up all attached metadata — no more frustrations!

Besides that, I also cover a few of the most interesting new possibilities in Drupal 8:

  • anonymous page loads: invalidating Varnish/CDNs with perfect precision
  • authenticated page loads: not completely regenerated on every page load, but assembled from render cached parts
  • alternative render strategies, like Big Pipe

Update (November 14, 2014): since I gave this talk, https://www.drupal.org/node/2352155 was committed, so this talk is now indeed a comprehensive, correct talk about the finalized Drupal 8 render pipeline!

Update (March 20, 2015): there is now an official Drupal 8 documentation page: https://www.drupal.org/developing/api/8/render/pipeline.
