Hexo使用gulp优化

//用到的各个插件
var gulp = require('gulp');
var cleanCSS = require('gulp-clean-css');
var htmlmin = require('gulp-html-minifier-terser');
var htmlclean = require('gulp-htmlclean');
// gulp-tester
var terser = require('gulp-terser');
// 压缩js
gulp.task('compress', () =>
  gulp.src(['./public/**/*.js', '!./public/**/*.min.js'])
    .pipe(terser())
    .pipe(gulp.dest('./public'))
)
//压缩css
gulp.task('minify-css', () => {
    return gulp.src(['./public/**/*.css'])
        .pipe(cleanCSS({
            compatibility: 'ie11'
        }))
        .pipe(gulp.dest('./public'));
});
//压缩html
gulp.task('minify-html', () => {
    return gulp.src('./public/**/*.html')
        .pipe(htmlclean())
        .pipe(htmlmin({
            removeComments: true, //清除html注释
            collapseWhitespace: true, //压缩html
            collapseBooleanAttributes: true,
            //省略布尔属性的值，例如：<input checked="true"/> ==> <input />
            removeEmptyAttributes: true,
            //删除所有空格作属性值，例如：<input id="" /> ==> <input />
            removeScriptTypeAttributes: true,
            //删除<script>的type="text/javascript"
            removeStyleLinkTypeAttributes: true,
            //删除<style>和<link>的 type="text/css"
            minifyJS: true, //压缩页面 JS
            minifyCSS: true, //压缩页面 CSS
            minifyURLs: true  //压缩页面URL
        }))
        .pipe(gulp.dest('./public'))
});

// 运行gulp命令时依次执行以下任务
gulp.task('default', gulp.parallel(
  'compress', 'minify-css', 'minify-html'
))
