Gulp

    Gulp是一个自动化构建工具，可以帮助前端开发者通过自动化任务来管理工作流程。Gulp使用Node.js的代码编写，可以更加灵活地管理代码以及任务流程.

   对于Vue.js前端框架，使用Gulp并不是必须的，因为Vue.js提供了Vue-cli，可以帮助前端开发者快速搭建项目以及项目的构建环境。Vue-cli是一个基于Webpack的脚手架工具，可以快速创建Vue.js应用程序，并且帮助生成项目骨架以及构建系统。其内置了webpack、Babel、ESLint等工具，可以方便地进行模块打包、ES6转换、代码检查等。使用Vue-cli，可以弹性地对项目进行管理和构建。

   但是对于一些需要个性化开发的开发者来说，Vue-cli的功能是不够的。前端开发者需要使用其他的构建工具来满足他们的需求，比如Gulp。使用Gulp可以帮助开发者扩展Vue-cli的功能，同时使构建流程更加简单，例如使用Gulp可以定制SASS/LESS文件编译、CSS文件合并压缩、JS文件压缩混淆、图片压缩等等。这样可以方便地定制应用程序及其构建流程，同时减少重复操作。

   而且，使用Gulp也可以减少构建速度。Vue-cli虽然帮助我们构建了项目骨架以及构建环境，但是在打包大规模的代码时，打包速度较慢。使用Gulp可以在webpack后处理流程中进行Sass编译、Html统一压缩等操作，并提高构建速度。

   总之，对于Vue.js前端框架，使用Gulp并不是必须的，但是它提供了扩展功能、使构建流程更加简单、加快了打包速度等优点。使用Gulp进行项目的构建可以为前端开发者节省时间、精力，并且优化构建方式。因此，个性化开发需要Gulp的前端开发者可以使用它对Vue-cli进行扩展，而其余开发者可以继续使用Vue-cli快速构建Vue.js应用程序。

VUE使用Gulp

Vue安装Gulp

   首先，我们需要安装所需的依赖。我们需要全局安装Gulp，通过npm命令安装：

  npm install -g gulp-cli

    接下来，我们需要在项目根目录下安装Gulp和其他依赖（比如babel、browserify等）：

   npm install gulp babelify browserify gulp-babel gulp-rename gulp-sourcemaps gulp-uglify vinyl-buffer vinyl-source-stream vueify --save-dev

Vue定义Gulp.js

gulpfile.js代码如下：

var gulp = require('gulp');

var $    = require('gulp-load-plugins')();

var path = require('path');

var del  = require('del');

var version     = ''; // 版本号

var versionPath = ''; // 版本号路径

// prod-运行环境  qa-测试环境

var env         = process.env.npm_config_qa ? 'qa' : process.env.npm_config_uat ? 'uat' : 'prod';

// 文件夹

var distPath    = path.resolve('./dist');

// 创建版本号(年月日时分)

(function () {

  var d = new Date();

  var yy = d.getFullYear();

  var MM = d.getMonth() + 1 >= 10 ? (d.getMonth() + 1) : '0' + (d.getMonth() + 1);

  var DD = d.getDate() >= 10 ? d.getDate() : '0' + d.getDate();

  var h  = d.getHours() >= 10 ? d.getHours() : '0' + d.getHours();

  var mm = d.getMinutes() >= 10 ? d.getMinutes() : '0' + d.getMinutes();

  version = "" + yy + MM + DD + h + mm;

  versionPath = distPath + '/' + version;

})();

// 编译

if('qa'===env){

  gulp.task('build', $.shell.task([ 'node build/build-qa.js' ]));

}else if('prod'===env){

  gulp.task('build', $.shell.task([ 'node build/build-prod.js' ]));

}

// 创建版本号目录

gulp.task('create:versionCatalog', function () {

  return gulp.src(`${distPath}/static/**/*`)

    .pipe(gulp.dest(`${versionPath}/static/`))

});

// 替换${versionPath}/static/js/manifest.js window.SITE_CONFIG.cdnUrl占位变量

gulp.task('replace:cdnUrl', function () {

  return gulp.src(`${versionPath}/static/js/manifest.js`)

    .pipe($.replace(new RegExp(`"${require('./config').build.assetsPublicPath}"`, 'g'), 'window.SITE_CONFIG.cdnUrl + "/"'))

    .pipe(gulp.dest(`${versionPath}/static/js/`))

});

// 替换${versionPath}/static/config/index-${env}.js window.SITE_CONFIG['version']配置变量

gulp.task('replace:version', function () {

  return gulp.src(`${versionPath}/static/config/index-${env}.js`)

    .pipe($.replace(/window.SITE_CONFIG′version′ = '.*'/g, `window.SITE_CONFIG['version'] = '${version}'`))

    .pipe(gulp.dest(`${versionPath}/static/config/`))

});

// 合并${versionPath}/static/config/[index-${env}, init].js 至 ${distPath}/config/index.js

gulp.task('concat:config', function () {

  return gulp.src([`${versionPath}/static/config/index-${env}.js`, `${versionPath}/static/config/init.js`])

    .pipe($.concat('index.js'))

    .pipe(gulp.dest(`${distPath}/config/`))

});

//清除, 编译 / 处理项目中产生的文件

gulp.task('cleanBuild', function () {

  return del([`${distPath}/static`, `${versionPath}/static/config`])

});

// 清空

gulp.task('clean', function () {

  return del([versionPath])

});

//gulp.series|4.0 依赖

//gulp.parallel|4.0 多个依赖嵌套

gulp.task('default',gulp.series(gulp.series('build','create:versionCatalog','replace:cdnUrl','replace:version','concat:config','cleanBuild')));
