Hexo使用gulp压缩静态资源

hexo作为静态页面来说加载速度已经很快了，但是我们仍然可以通过基于Node.js名为gulp的自动化构建工具实现对html、css、js等静态资源的压缩，进一步优化博客访问速度。

先安装gulp

npm install gulp -g

安装gulp所需要的模块

要实现gulp压缩需要安装以下五个模块

• gulp-htmlclean：清理html
• gulp-htmlmin：压缩html
• gulp-minify-css：压缩css
• gulp-uglify：混淆js
• gulp-imagemin：压缩图片

npm install gulp-htmlclean gulp-htmlmin gulp-minify-css gulp-uglify gulp-imagemin --save

创建gulpfile.js文件

在博客根目录下，新建gulpfile.js文件，文件内容如下

//Plugins模块获取
var gulp = require('gulp');
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',  async function () {
return gulp.src('./public/**/*.css')
.pipe(minifycss())
.pipe(gulp.dest('./public'));
});

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

// 压缩 public/images 目录内图片(Version>3)
gulp.task('minify-images', async function (done) {
    gulp.src('./public/images/**/*.*')
        .pipe(imagemin([
            imagemin.gifsicle({interlaced: true}),
            imagemin.jpegtran({progressive: true}),
            imagemin.optipng({optimizationLevel: 5}),
            imagemin.svgo({
                plugins: [
                    {removeViewBox: true},
                    {cleanupIDs: false}
                ]
            })
        ]))
        .pipe(gulp.dest('./public/images'));
    done();
});
// 开始任务
gulp.task('default', gulp.parallel('minify-html', 'minify-css',  async function() {
  // Do something after a, b, and c are finished.
}));
