basic angularjs/angular1 graphql query using $http

app.js

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope, $http) {
  query = `{ allItems {
             id
           }}`
  $http
    .post('<graphql endpoint>', { query: query })
    .then(function(resp) {
      $scope.response = resp.data
    })
});

This works with a graph.cool endpoint. Not tested anywhere else.
