This module provides a Views filter to only show the nodes that the current user is allowed to edit. This is typically useful as an UX improvement for editors on the /admin/content page.
This project provides a service and context to determine if the current route match is owned by a particular entity type, by way of link templates.
A context is also provided for plugins and other to consume. For example you may want to create a block, or DsField, that relies on a particular entity from the route. It operates similar to the node.node_route_context context, but in an entity type agnostic way. Entity type specific contexts are also available in case a plugin is designed to take any entity type, but as a site builder you may choose for it to respond to a particular entity type.
