Use systemjs/plugin-text to import html directly to $routeProvider or $templateCache, works great with jspm bundle.

directive.js

import somethingHTML from './something.html!text';

angular.module('myApp',[])
  .directive('myDirective', function() {
    return {
      template: somethingHTML
    }
  });

includes.js

import somethingHTML from 'components/something/something.html!text';

angular.module('myApp',[])
  .run(function($templateCache) {
    $templateCache.put('components/something/something.html', somethingHTML);
  });

routes.js

import somethingHTML from 'components/something/something.html!text';

angular.module('myApp',[])
  .config(function($routeProvider) {
    $routeProvider
    .when('/something', {
      template: somethingHTML,
    })
  });

they are all different examples of the same thing
