Angular.js factory to load preload templates.

preload-templates.js

app.factory('$preload', ['$templateCache', '$http',
  function ($templateCache, $http) {
    // angular.js preload template factory, the purpose of this
    // is to preload all of your applications templates, once.
    // all callbacks should fire with (err, data) node.js style
    // flow.
    var internalHttpRequest = function (url, fn) {
      $http.get(url).success(function (data) {
        return fn(data);
      });
    };
    var preload = function (templates, fn) {
      var templates = templates || [];
      if (templates.length) {
        templates.forEach(function (template) {
          internalHttpRequest(template, function (html) {
            $templateCache.put(template, html);
          });
        });
        return fn(null, true);
      } else {
        return fn(true, null);
      }
    };
    return preload;
  }]);

How do I get all URLs templates?
You use an array of URLs...

I'm doing this but I have too many.

$http.get('views/asistente/historial.html', { cache: $templateCache }).then(() => { }, error)
$http.get('views/asistente/historial.pedidointerno.html', { cache: $templateCache }).then(() => { }, error) $http.get('views/asistente/historial.recetas.html', { cache: $templateCache }).then(() => { }, error) $http.get('views/asistente/historial.transferencias.html', { cache: $templateCache }).then(() => { }, error)
