I encountered an issue on a Drupal 11 site recently where I had a block that was rendering an entity to display on a page.
There was nothing unusual about what was going on in the rendering process, but in this case I needed to add some attributes to the entity markup and I found that this process wasn't that simple. The solution was to intercept the rendering process half way through using a pre-rendering callback method.
As it wasn't that simple I took some notes and decided to convert them into an article to show how to do the same. In this article we will look at using the view builder to generate a renderable view of an entity and then look at how to alter the attributes of the view mode without using a preprocess hook.
