知识点

这个配置方案，支持less、postcss的autoprefixer、代码压缩、es6、模板引用等。
下面是部分知识点的说明。

设置及使用环境变量

cross-env

1. 下载 npm install --save-dev cross-env
2. 配置

// package.json
{
  // ...
  "scripts": {
    "dev": "cross-env NODE_ENV=development gulp serve",
    "build": "cross-env NODE_ENV=production gulp serve"
  }
}

1. 使用

// gulpfile.js
var isDev = !(process.env.NODE_ENV === 'production');

支持es6

webpack-stream
babel-loader

模板引用

复用 html 公用部分
gulp-file-include

html 中路径前缀使用变量

gulp-template
本项目中，主要用来处理 html 文件中，不同环境下 js、css文件引入路径前缀的动态编译问题。

开发过程中请求跨域解决方案

http-proxy-middleware

上传至服务器

gulp-sftp

// 测试 - 上传至服务器
gulp.task('dev-build', () => {
  return gulp.src('./dist/**')  // 上传 dist 文件夹下所有内容
    .pipe(sftp({
      remotePath: '/App/web/phpcms/test/yxb-web',  // 上传目录
      host: '192.168.11.11',  // 服务器地址
      user: 'root',  // 用户名
      pass: '123456'  // 密码
    }))
})
