The API returns a result corresponding to the query in JSON format.

Queries define what type of data and what fields of the data are requested. Queries are written in GraphQL language and sent to the API in request body of a HTTP POST request with either 'application/graphql' or 'application/json' as Content-Type. Using GraphQL Creating and sending queries Response Regardless of the method by which the query and variables were sent, the response should be returned in the body of the request in JSON. If you're using express-graphql, you already get these behaviors for free. The server then parses the query, executes it, and returns the results back to client. json-to-graphql-query - npm json-to-graphql-query This is a simple module that takes a JavaScript object and turns it into a GraphQL query to be sent to a GraphQL server. If the 'application/graphql' Content-Type header is present, treat the HTTP POST body contents as the GraphQL query string. Instead of the client calling REST-like urls, it generates different GraphQL queries and sends these queries to the single endpoint of the API.

When implementing a GraphQL API, server developers specify a GraphQL schema that defines what can be queried. Basically, you can think of it as “client side SQL”. GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data.
