The latest version of Dgraph 20.03.1 contains GraphQL endpoint. We're releasing few more features very soon, which would add object level auth, ability to trigger custom logic, call remote GraphQL endpoints to execute part of the query, and so on. So, you could put Dgraph directly in front of a frontend, without worry.

Dgraph can also be called via Apollo Gateway, as part of their federation.

We also have other very interesting stuff in the pipeline, which would cater a lot to front end development as well as backend. So, stay tuned.
