RESTful, JSON-delivering APIs are today’s default choice when building an API. GraphiQL is an excellent tool which generates documentation of the query and its schema. A GraphQL query, on the other hand, returns exactly what a client asks for and no more. On the server, we configure the GraphQL system to map queries to underlying data-fetching code. First, this gets at a very specific problem that comes up in implementations using GraphQL ; so in order to understand the problem you have to have a decent understanding of GraphQL. In an example, if the client needs a field, they request it, and if the API adds a new field, clients don't get it, unless it's being added into the GraphQL query.
