Minimal graphql example

graphql-exmaple.js

const {
  graphql,
  GraphQLSchema,
  GraphQLObjectType,
  GraphQLString,
} = require('graphql');

const schema = new GraphQLSchema({
  query: new GraphQLObjectType({
    name: 'Query',
    fields: {
      serverTime: {
        type: GraphQLString,
        resolve() {
          return (new Date).toLocaleString();
        }
      }
    },
  })
});

const query = `{
  serverTime
}`;

graphql(schema, query).then(result => {console.log(result);});

// Prints:
// {data: {serverTime: "9/5/2016, 6:28:46 PM"}}
