WebStorm学习笔记002---grunt-watch插件的使用-修改html,css,js文件实现自动编译更新

配置css和js文件发生变化就重新合并压缩css和js文件

package.json

{
  "name": "AngularAndRequire",
  "version": "0.1.0",
  "description" : "AngularAndRequire1.0",
  "author": "Mario.Li",  
  "devDependencies": {

    "grunt-contrib-concat": "~0.1.1",
    "grunt-contrib-watch": "~0.6.1",
    "grunt-css": "~0.5.4"
  }
}

Gruntfile.js

'use strict'  
module.exports = function(grunt) {
    // 配置
    grunt.initConfig({
        pkg : grunt.file.readJSON('package.json'),
        concat : {
            libs : {
                src: ['frontend/libs/*.js', '!frontend/libs/require.js'],
                dest: 'dest/libs.js'
            },
            custs: {
                src: ['frontend/**/*.js', '!frontend/libs/*.js'],
                dest: 'dest/cust.js'
            },
            css : {
                src : ['frontend/styles/*.css', '!frontend/styles/index.css'],
                dest : 'dest/index.css'
            }
        },
        uglify : {
            options : {
                banner : '/*! <%= pkg.name %> <%= grunt.template.today("yyyy-mm-dd") %> */\n'
            },
            buildlibs : {
                src : 'dest/libs.js',
                dest : 'dest/libs.min.js'
            },
            buildcusts : {
                src : 'dest/cust.js',
                dest : 'dest/cust.min.js'
            },
        },
        cssmin : {
            buildCss : {
                src : 'dest/index.css',
                dest : 'dest/index.min.css'
            }
        },
        watch : {
            all : {
                files :['**/*.js', '**/*.css'],
                tasks : ['concat', 'uglify', 'cssmin']
            }
        }
    });
    // 载入concat和uglify插件，分别对于合并和压缩
    grunt.loadNpmTasks('grunt-contrib-watch');  
    grunt.loadNpmTasks('grunt-css');
    grunt.loadNpmTasks('grunt-contrib-concat');
    grunt.loadNpmTasks('grunt-contrib-uglify');
    // 注册任务
    grunt.registerTask('default', ['concat', 'uglify', 'cssmin', 'watch']);
};
