grunt之easy demo

首先安装grunt-cli

cnpm install -g grunt-cli

接下来创建package.json,内容如下

    {
      "name": "demo",
      "file": "zepto",
      "version": "0.1.0",
      "description": "demo",
      "license": "MIT",
      "devDependencies": {
        "grunt": "~0.4.1",
        "grunt-contrib-jshint": "~0.6.3",
        "grunt-contrib-concat": "~0.5.0",
        "grunt-contrib-uglify": "~0.2.1",
        "grunt-contrib-requirejs": "~0.4.1",
        "grunt-contrib-copy": "~0.4.1",
        "grunt-contrib-clean": "~0.5.0",
        "grunt-strip": "~0.2.1"
      },
      "dependencies": {
        "express": "3.x"
      }
    }

也可以使用npm init来进行初始化

创建Gruntfile.js,只做合并和压缩

    module.exports = function (grunt) {
      grunt.initConfig({
      concat: {
        options: {
        },
        dist: {
          src: ['src/**/*.js'],//src文件夹下包括子文件夹下的所有文件
          dest: 'dist/built.js'//合并文件在dist下名为built.js的文件
        }
      },
      uglify: {
         build: {
            src: 'dist/built.js',//压缩源文件是之前合并的buildt.js文件
            dest: 'dist/built.min.js'//压缩文件为built.min.js
          }
       }
    });
      grunt.loadNpmTasks('grunt-contrib-uglify');
      grunt.loadNpmTasks('grunt-contrib-concat');

      grunt.registerTask('default', ['concat','uglify']);
    }
