How to use the graphql function from graphql

graphql.graphql is a function in the graphql library that takes a schema and a query and returns the result of executing that query against the schema.

How does graphql.graphql work?

graphql.graphql is a function in the graphql library that executes a GraphQL query against a given schema. Here is the basic syntax of using graphql.graphql: javascript Copy code {{{{{{{ const { graphql } = require('graphql'); graphql(schema, query) .then((result) => { // handle the result of the query }); In this example, graphql.graphql is being called with a GraphQL schema and a query string as its two arguments. The schema argument is an instance of the GraphQLSchema class, which represents the entire GraphQL schema of the application. The query argument is a string representing the GraphQL query that will be executed against the schema. The graphql.graphql function then returns a promise that resolves to the result of executing the query against the schema. The result of the query is an object that contains the data returned by the query as well as any errors that occurred during execution. Overall, graphql.graphql provides a simple and convenient way to execute GraphQL queries against a given schema, making it a key part of any GraphQL server implementation.

const { graphql, buildSchema } = require("graphql");

// Define a schema for a simple "Hello World" query
const schema = buildSchema(`
type Query {
hello: String
}
`);

// Define a resolver function for the "hello" field
const rootValue = {
  hello: () => "Hello World!",
};

// Execute the "hello" query against the schema
graphql(schema, "{ hello }", rootValue).then((result) => {
  console.log(result.data.hello); // Outputs "Hello World!"
});

In this example, we first define a GraphQL schema that includes a single field called "hello". We then define a resolver function for the "hello" field that returns the string "Hello World!". We then call graphql.graphql with the schema, the query { hello }, and the resolver function rootValue. The result of executing the query is returned as a promise, which we handle in the .then block by logging the value of the hello field in the query result. This is a simple example, but it demonstrates the basic mechanics of using graphql.graphql to execute GraphQL queries against a schema.
