如何利用 gulp 压缩混淆 “上古”时期的项目文件

最近一段时间，在做一个很古老的项目，简直是上古时期的写作方式了。

还是那些传统的方式，一个页面从上到下引入几十个「js」文件，里面到处充斥着 jquery 的 DOM 操作，维护起来相当的糟糕，变量与函数之间跨文件引用。

虽然很难，但是经过一段时间的努力吧，算是有个稳定的版本了，所以在上线之前呢，我们是需要把代码给压缩混淆一下，一来是减少文件的体积，二来是去掉源码的可读性。

接下来，我们就直接进入主题，废话不多少，如何利用 gulp 去做代码的压缩与混淆。

至于 gulp 是什么我就不做过多的解释了，它是一个自动化的构建工具。

安装

全局安装 gulp

npm install --global gulp

作为项目的依赖安装

npm install --save-dev gulp

创建文件

在项目的根目录下，创建名为 gulpfile.js 的文件

var gulp = require('gulp');

gulp.task('default', function() {
  //需要处理的任务
});

运行

gulp taskname

压缩html

//压缩html
gulp.task("minhtml", function () {
  gulp.src("./src/*.html")
    .pipe(htmlmin({
      collapseWhitespace: true, //去空格
      removeComments: true //去注释
    }))
    .pipe(gulp.dest("./dist"))
});

压缩css

//压缩css
gulp.task("mincss", function () {
  gulp.src("./src/*.css")
    .pipe(cssmin())
    .pipe(gulp.dest("./dist/css"));
});

压缩混淆js

//压缩js
gulp.task("minjs", function () {
  return gulp.src("./src/js/*.js")
    .pipe(uglify())
    .pipe(gulp.dest("./dist/js")
});

以上，就可以愉快的一键压缩我们的代码了，当然项目中肯定不止这么简单的需求，还有更多更玩的，大家可以根据自己的需求定制一些个性话东西。
