Grunt是一个JavaScript任务运行器
Grunt基于Node.js，用JS 开发，这样就可以借助Node.js实现跨系统跨平台的桌面端的操作，例如文件操作等等。此外，Grunt以及它的插件们，都作为一个包，可以用 NPM 安装进行管理。
操作步骤
npm install -g grunt-cli 安装grunt的命令行工具
npm init 生成package.json文件
npm install grunt --save-dev 安装grunt并加入到依赖
npm install --save-dev grunt-contrib-concat grunt-contrib-jshint grunt-contrib-sass grunt-contrib-uglify grunt-contrib-watch grunt-contrib-connect 安装常用插件并加入到依赖
其中 :
合并文件：grunt-contrib-concat
语法检查：grunt-contrib-jshint
Scss 编译：grunt-contrib-sass
压缩文件：grunt-contrib-uglify
监听文件变动：grunt-contrib-watch
建立本地服务器：grunt-contrib-connect
angular 缓存模板 : grunt-angular-templates
复制文件 : grunt-contrib-copy
删除文件 : grunt-contrib-clean
压缩以及合并CSS文件 : grunt-contrib-cssmin
图像压缩模块 : grunt-contrib-imagemin主目录下创建Gruntfile.js,并进行配置
输入grunt执行default,或 grunt 对应名 执行对应操作
js压缩uglify示例:
module.exports = function(grunt) {
// 配置任务
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),//固定写法
uglify: {
options: {//通用配置(会被私有配置覆盖)
banner: '/*! <%= pkg.name %> <%= grunt.template.today("yyyy-mm-dd") %> */\n',
footer:'\n/*! 我是footer */'
},
builda: {//按原目录批量压缩
expand:true,//允许使用占位符*代替其他字符
cwd:'oldjs',//只压缩该目录下的文件
src: '**/*.js',//**表示任意包括/和空,因此可以用于表示多层文件
dest: 'newjs',//目标文件夹
ext:'.min.js'//压缩文件后缀名
},
buildb:{
options:{//私有配置
mangle:false,//不进行代码混淆
banner:'//hello nihao\n'
},
files:{
'out/out.js':['jss/**/*.js','src/hello.js']//合并压缩
}
}
}
});
//加载插件
grunt.loadNpmTasks('grunt-contrib-uglify');//加载插件
//任务注册
grunt.registerTask('aa', ['uglify:builda']);
grunt.registerTask('bb', ['uglify:buildb']);//输入grunt bb则运行uglify中的buildb方法
grunt.registerTask('default', ['uglify']);//输入grunt 即可运行整个uglify
};
