GraphQL is a emerging technology developed internally by Facebook and open-sourced right after. It is aimed to be a replacement of the REST API and more and more developers are buying the idea. GraphQL poses a declarative way of fetching and update data and thus simplifying the process of doing so on the front-end. Dealing with the server side of a GraphQL stack might be a bit more complex than building REST API endpoints, but the benefit is worth the challenge and fortunately there are several libraries out there that can help you build GraphQL servers.
