gulp 压缩

gulp is a toolkit for automating painful or time-consuming tasks in your development workflow, so you can stop messing around and build something.

我们可以使用 gulp 压缩 hexo 站点使用的静态资源,从而提高站点的访问速度。

安装过程:

npm install gulp -g

同时需要安装下面这些用到的模块:

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

然后我们需要在博客根目录新建gulpfile.js文件来编写gulp task对应的函数:

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');
var imagemin = require('gulp-imagemin');

// 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 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-html','minify-css','minify-js','minify-images'
));

需要注意的是在默认任务中,gulp.parallel()gulp4中的新写法。

然后每次执行 hexo clean && hexo g && gulp && nohup hexo s &
