React Express

GraphQL is a query language for APIs. It enables declarative data fetching and thus ties in perfectly with React as a declarative framework for building user interfaces. GraphQL can either complement or entirely replace the usage of REST APIs.
The main difference between REST and GraphQL is that RESTful APIs have multiple endpoints that return fixed data structures whereas a GraphQL server only exposes a single endpoint and returns flexible data structures. This works because a client that needs data from the server also submits its precise data requirements in each request which allows the server to tailor the response exactly according to the client’s needs.
