GraphQL is a technology that helps developers across the board to build more robust software more quickly. The ability to request all of the information you need in a single request is a game-changer. It has simplified my backend development of APIs for consumption by mobile and web applications that would normally rely on RESTful APIs. A normal RESTful API may have several endpoints for various entities (e.g. users, submissions, etc.); with GraphQL, you can get all of this information in a single go using GraphQL’s query language, also known as GQL.
