Basic GraphQL example using the GitHub API

import { graphql, GraphQLString, GraphQLInt } from 'graphql'; import { objectType, enumType, schemaFrom, listOf } from 'graphql-schema'; import request from 'promisingagent';

const repositorySortEnum = enumType('RepositorySort') .value('CREATED', 'created') .value('UPDATED', 'updated') .value('PUSHED', 'pushed') .value('FULL_NAME', 'full_name') .end();

const repositoryType = objectType('Repository') .field('id', GraphQLString) .field('name', GraphQLString) .field('owner', () => userType) .field('description', GraphQLString) .end();

const userType = objectType('User') .field('id', GraphQLString) .field('name', GraphQLString) .field('login', GraphQLString) .field('location', GraphQLString) .field('repositories', listOf(repositoryType)) .arg('first', GraphQLInt) .arg('orderby', repositorySortEnum) .resolve((user, {first, orderby}) => fetchRepositoriesFor(user.name, first, orderby)) .end();

const queryType = objectType('Query') .field('user', userType) .arg('name', GraphQLString) .resolve((root, {name}) => fetchUser(name)) .end();

const query = { user(name: "facebook") { name, repositories(first: 5, orderby: FULL_NAME) { name, description } } };

graphql(schemaFrom(queryType), query).then(result => { console.log(JSON.stringify(result)); });

function fetchUser(name) { return request .get(https://api.github.com/users/${name}) .end().then(result => { return result.body; }); }

function fetchRepositoriesFor(name, first, orderby) { return request .get(https://api.github.com/users/${name}/repos?per_page=${first}&sort=${orderby}) .end().then(result => { return result.body; }); }
