安装

requirejs

npm install -g requirejs

安装好后：

找到刚刚requirejs的安装目录，在该目录下找到r.js，并拷贝待压缩合并项目的根目录下
在项目根目录下创建build.js

build.js 示例

{
    //The directory path to save the output.
    //All relative paths are relative to the build file.
    dir: "./build",
    //All modules are located relative to this path
    baseUrl: "./src",
    //the main script of the project which contain the configuration for the app
    //if set, all config below is not neccesory
    mainConfigFile: './src/js/app.js',
    //module you want to optimize(the entry file which require modules)
    //path relative to the baseUrl
    name: "js/app/rtest",
    //out: 'js/app/build.js', //used in optimize one file
    //fileExclusionRegExp: /^(app)\.js$/, //file which will be skipped
    paths: { //path of files
        'lodash': 'js/lib/lodash/dist/lodash',
        'jquery': 'js/lib/jquery/dist/jquery.min',
        'when': 'js/lib/when/when'
    },
    shim: {
        'jquery': {
            exports: '$'
        }
    }
}
