gulp优化hexo方法

gulp通过对站点使用的静态资源进行压缩，来优化网站的访问速度。

首先安装gulp以及所需要的模块：

npm install gulp -g

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

然后在博客的根目录下创建gulpfile.js文件写入代码：

var gulp = require('gulp');
var minifycss = require('gulp-minify-css');
var uglify = require('gulp-uglify');
var imagemin = require('gulp-imagemin');
 
// 压缩css
gulp.task('minify-css', function() {
    return gulp.src('./public/**/*.css')
        .pipe(minifycss({
            compatibility: 'ie8'
        }))
        .pipe(gulp.dest('./public'));
});
// 压缩js
gulp.task('minify-js', function() {
    return gulp.src('./public/js/**/*.js')
        .pipe(uglify())
        .pipe(gulp.dest('./public'));
});
// 压缩图片
gulp.task('minify-images', function() {
    return gulp.src('./public/images/**/*.*')
        .pipe(imagemin(
        [imagemin.gifsicle({'optimizationLevel': 3}),
        imagemin.jpegtran({'progressive': true}),
        imagemin.optipng({'optimizationLevel': 7}),
        imagemin.svgo()],
        {'verbose': true}))
        .pipe(gulp.dest('./public/images'))
});
// 默认任务
gulp.task('default', gulp.parallel(
    'minify-css','minify-js','minify-images'
));

最后执行命令，上传GitHub
