Rabbit Hole is a module that adds the ability to control what should happen when an entity is being viewed at its own page.

Entity Query API fills the gap between Drupal 8's built-in RESTful Services and Views with an easy to use, out-of-the-box means for loading, filtering and paging entities in a RESTful style. Essentially, this module provides an API to the Entity QueryInterface.

This provides user interface integration for the simple yet powerful Replicate API. Most notably, this provides integration with Drupal actions which means that you can start to replicate things via the user interfaces with built in support for:

Drupal core nodes
Drupal core actions
"Any" Drupal Entity available to Entity API (see hook_menu)
Views
Views Bulk Operations
Rules
Field Collections
