使用r.js进行前端repuirejs的合并压缩

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$/, //file which will be skipped
paths: { //path of files
'lodash': 'js/lib/lodash/dist/lodash',
'jquery': 'js/lib/jquery/dist/jquery.min',
'when': 'js/lib/when/when'
},
shim: {
'jquery': {
exports: '$'
}
}
}

配置

doc of build.js

运行

node r.js -o build.js

你会看到:build文件夹被创建,同步引入的文件被合并到入口文件中,异步文件保留。目录下的所有文件都被压缩。
