mvc bundle功能(1)

现如今都提倡敏捷开发,快速开发,但是再要求速度的同时,还得保证质量!前端我是没办法,毕竟是直接要面向用户的,但是后台,解决方案那就多了,诸如extjs,bootstrap,kendoui,都可以解决。但是使用了这些第三方的东西,我们的后台是漂亮了,效果也炫了,新的问题就来了,大量的引用js、css。

 

这是我用bootstrap、kendoui搭的一个标准后台,代码非常简洁,但是引用了很多样式和js,加载完这个页面发送了又16个请求,耗时1.36s。

有没有一种方法可以把这些js和css合并起来并且压缩一下呢?这样我们的后台效果不就更好了吗?当然有,.net mvc自带的bundle功能。我们先看使用了该功能之后是什么效果

很明显,请求数减少了,响应时间也减少了,那我们来看看bundle到底是如何实现的。

 1 public class BundleConfig

74                         "~/Content/themes/base/jquery.ui.slider.css",
75                         "~/Content/themes/base/jquery.ui.tabs.css",
76                         "~/Content/themes/base/jquery.ui.datepicker.css",
77                         "~/Content/themes/base/jquery.ui.progressbar.css",
78                         "~/Content/themes/base/jquery.ui.theme.css"));
79         }
80     }

首先需要首先需要配置Bundle

 1 public class MvcApplication : System.Web.HttpApplication
 2     {
 3         protected void Application_Start()
 4         {
 5             AreaRegistration.RegisterAllAreas();
 6 
 7             WebApiConfig.Register(GlobalConfiguration.Configuration);
 8             FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
 9             RouteConfig.RegisterRoutes(RouteTable.Routes);
10             BundleConfig.RegisterBundles(BundleTable.Bundles);
11             AuthConfig.RegisterAuth();
12         }
13     }

再全局注册Bundles
