Hexo-使用gulp插件压缩页面静态资源

安装 gulp

$ npm install gulp -g
$ npm install gulp-minify-css gulp-uglify gulp-htmlmin gulp-htmlclean gulp --save

或者使用yarn 
yarn global add gulp
yarn add gulp-minify-css gulp-uglify gulp-htmlmin gulp-htmlclean gulp

配置 gulpfile.js

在hexo根目录新增 gulpfile.js

var gulp = require('gulp');

//Plugins模块获取
var minifycss = require('gulp-minify-css');
var uglify = require('gulp-uglify');
var htmlmin = require('gulp-htmlmin');
var htmlclean = require('gulp-htmlclean');
//压缩css
gulp.task('minify-css', function () {
  return gulp.src('./public/**/*.css')
  .pipe(minifycss())
  .pipe(gulp.dest('./public'));
});
//压缩html
gulp.task('minify-html', function () {
  return gulp.src('./public/**/*.html')
  .pipe(htmlclean())
  .pipe(htmlmin({
    removeComments: true,
    minifyJS: true,
    minifyCSS: true,
    minifyURLs: true,
  }))

  .pipe(gulp.dest('./public'))
});
//压缩js 不压缩min.js
gulp.task('minify-js', function () {
  return gulp.src(['./public/**/*.js', '!./public/**/*.min.js'])
  .pipe(uglify())
  .pipe(gulp.dest('./public'));
});

//4.0以前的写法 
//gulp.task('default', [
  //  'minify-html', 'minify-css', 'minify-js'
//]);
//4.0以后的写法
// 执行 gulp 命令时执行的任务
gulp.task('default', gulp.parallel('minify-html', 'minify-css', 'minify-js', function() {
  // Do something after a, b, and c are finished.
  return new Promise(function(resolve, reject) {
    console.log("gulp finished");
    resolve();
  }
  )}
  ));

以后生成博文时执行 hexo g && gulp 就会根据 gulpfile.js 中的配置，对 public 目录中的静态资源文件进行压缩。
