# loadWithXhr

#### loadWithXhr(options) → Promise.<Object>

  Asynchronously loads the given URL. Returns a promise that will resolve to the result once loaded, or reject if the URL failed to load. The data is loaded using XMLHttpRequest, which means that in order to make requests to another origin, the server must have Cross-Origin Resource Sharing (CORS) headers enabled.

          responseType : 'blob'
      }).then(function(blob) {

      }).otherwise(function(error) {
          // an error occurred
      });
