RestToRender Mobile页面的加载性能整体解决方案 One-Request，基于Node/Grunt的自动化Watch和Build，将外联资源可配置的Combo成One-Request Page。 实践证明：在Mobile端，合理有效的减少http请求数是极其重要的加载性能优化方法。

Useage

$ npm install -g yo
$ npm install -g generator-onereq
$ yo onereq

接下来，就可以启动grunt进行愉快的编码了。

$ grunt

grunt 默认会启动 watch 模式，less/文件下的less文件会自动编译到build/css/文件下，js/文件夹下的js会自动压缩至build/js/目录下。

$ grunt build

grunt build 会自动将 带有 data-onereq 属性并引用本地文件的 <link> 和 <script> 标签自动替换为 css 和js的内容。Combo到html一起。在dest/目录下。

如果你有特殊需求，可以自行去修改增加 Gruntfile.js 和 package.json 的配置。

如果你不想用工程模板，可以直接使用独立的grunt插件 grunt-contrib-onereq

Gruntfile.js 配置类似：

onereq:  {
            options: {
                scriptClass: ['onereq'],
                minify: true
            },
            html: {
                files: [
                    {
                        cwd: './',
                        src: ['*.html', '*.htm'],
                        dest: 'dest/',
                        ext: '.html'
                    }
                ]
            }
        }

    |- js/
        - main.js
    |- less/

** grunt build **

$ cd app-name
$ grunt build

会自动生成 build/ 和 dest/ 目录。 build/ 目录 会把 js/ 和 less/ 目录下的 js 和 less文件分别编译压缩至 build/js/ 和 build/css/ 目录下 dest/ 目录下 会 自动把 根目录下的 .html 和 .htm 文件中引入的 带 data-onereq 的 css link 和 js 内容压缩并Combo至 dest/ 目录下。

dest/ 目录下 Combo 后的文件类似

One-Request的特性

  • 整合无线最新rem方案，直接在640宽的设计稿内量出设计尺寸a，less中对应尺寸直接a/40rem 即可。方便快捷适配所有mobile机型
  • Combo资源可选择性配置
  • images/下被less引用的图片将自动批量无损压缩，然后上传至cdn，并自动替换为绝对路径，省下太多力气【待完成...】
  • 根目录下的html文件自动检查，独立Combo
  • 同时完整兼容gitlab发布方案，css/*.less 和 src/*.js 经过编译和压缩后，会自动build至 build/ 目录下。
