 To handle GraphQL queries, we need a schema that defines the `Query` type, and we need an API root with a function called a “resolver” for each API endpoint. For an API that just returns “Hello world!”, we can put this code in a file named `server.js`:
 
-```javascript
-let { graphql, buildSchema } = require('graphql');
-
-// Construct a schema, using GraphQL schema language
-let schema = buildSchema(`
-  type Query {
-    hello: String
-  }
-`);
-
-// The rootValue provides a resolver function for each API endpoint
-let rootValue = {
-  hello() {
-    return 'Hello world!';
-  },
-};
-
-// Run the GraphQL query '{ hello }' and print out the response
-graphql({
-  schema,
-  source: '{ hello }',
-  rootValue,
-}).then((response) => {
-  console.log(response);
-});
