With config_devel, when you are editing a migration, you can just enter the name of the file being edited at admin/config/config_devel and on every request the module will check for changes and import the file into the active storage. The other direction works as well: say you are working on a contrib module and have a view. Provide the path of the file (this time in the auto export box) and on every change Drupal will automatically export. Once satisfied, just commit. Or perhaps you just want to follow what's in a config file as it's being edited -- provide sites/default/files/some.config.name.yml and it'll be right there on every save.
Both import and export are doable manually with the config module core provides. But I think the automatism makes life easier and I hope the module will be popular among D8 developers. Finally, let me thank beejeebus for cooking up the module originally and handing it over to me despite he knew I will rewrite it from the ground up.
Even though Drupal 7 core fell short of a proper way of handling its brand new entity system (we currently rely on the great Entity module for that), it did give us EntityFieldQuery. For those of you who don’t know, EntityFieldQuery is a very powerful querying class used to search Drupal entities programatically (nodes, users, etc).
It provides a number of methods that make it easy to query entities based on conditions such as field values or class properties. If you don’t know how it works, feel free to check out this documentation page or this great tutorial on the subject.
In this article I am going to talk about what we have in Drupal 8 for querying entities. There is no more EntityFieldQuery, but there’s an entity.query service that will instantiate a query object for a given entity type (and that implements the \Drupal\Core\Entity\Query\QueryInterface). We can access this service statically through the \Drupal namespace or using dependency injection.
First up, we’ll look at querying node entities and then we’ll see how to load them. The same techniques will work with other content entities as well (users, comments etc), but also with configuration entities, and that’s really cool.The entity query service
As mentioned, there are two ways we can access the entity.query service that we use for querying entities. Statically, we can do this:
