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
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。
