gulp中文API地址:http://www.gulpjs.com.cn/docs/api/

一些gulp插件的介绍:https://juejin.im/entry/55c8dbb160b22a3ebdf34d57

1.新建一个空项目文件夹，cd到该目录下初始化npm配置文件

此时在目录下多出一个package.json文件：

2.接下来我们需要初始化gulp依赖

npm install gulp --save-dev

运行完后会看到项目目录下多了一个node\_modules文件夹

并且在package.json里已经加上了dev的gulp属性项：

3.在项目根目录下添加一个gulpfile.js文件，这个是gulp的主文件

4.在gulpfile中抽象我们的任务

要实现这些任务需要安装对应的插件

5.gulpfile.js:

/**
     * Created by dyk-pc on 2017/5/31.
     */
    
    'user strict'
    
    //在gulpfile中先载入gulp包 因为这个包提供了一些api
    var gulp = require("gulp");
    var less = require('gulp-less');
    var cssnano = require('gulp-cssnano');
    var concat = require('gulp-concat');
    var uglify = require('gulp-uglify');
    var htmlmin = require('gulp-htmlmin');
    var browserSync = require('browser-sync');//浏览器同步
    
    //任务一：Less编译 压缩 合并
    gulp.task('style',function () {
        //这里是在执行style任务的时候自动执行的
        gulp.src('src/styles/*.less')
            .pipe(less())//把less编译为css
            .pipe(cssnano())//压缩
            .pipe(gulp.dest('dist/styles'))
            .pipe(browserSync.reload({
                stream:true
            }))
    })
    
    //任务二:Js合并 压缩 混淆
    gulp.task('script',function () {
        gulp.src('src/scripts/*.js')
            .pipe(concat('all.js'))
            .pipe(uglify())
            .pipe(gulp.dest('dist/scripts'))
            .pipe(browserSync.reload({
                stream:true
            }))
    })
    
    //任务三:img复制
    gulp.task('image',function () {
        gulp.src('src/images/*.*')
            .pipe(gulp.dest('dist/images'))
            .pipe(browserSync.reload({
                stream:true
            }))
    })
    
    //任务四:html压缩
    gulp.task('html',function () {
        gulp.src('src/*.html')
            .pipe(htmlmin({
                collapseWhitespace:true,
                removeComments:true
            }))
            .pipe(gulp.dest('dist'))
            .pipe(browserSync.reload({
                stream:true
            }))
    })
    
    //把任务架设在服务器 实现浏览器同步操作
    gulp.task('server',function () {
        browserSync({
            server:{
                baseDir:['dist']
            },
        },function (err,bs) {
            
        });
        gulp.watch('src/styles/*.less',['style']);
        gulp.watch('src/scripts/*.js',['script']);
        gulp.watch('src/images/*.*',['image']);
        gulp.watch('src/*.html',['html']);
    });
