Hexo Next 主题优化：使用 hexo-all-minifier 插件压缩代码

今天我对 Hexo 进行了一些优化，需要进行代码压缩。在网上找了很多的教程，大多数都使用 gulp 这个插件进行代码压缩，但我不建议大家使用。 因为我使用的过程中发现这个可能无法压缩部分 JS。导致出错，原因是较旧的 uglify 不支持 ES6。 所以我个人建议大家使用 hexo-all-minifier

hexo-all-minifier 介绍

hexo-all-minifier 项目地址：在 Github 查看 hexo-all-minifier 项目 引用一下官方说明：

Integrate all the official minifier plugins of HEXO and a imagemin plugin: 译：本插件集成了 Hexo 官方 minifier 插件和 imagemin 插件：

• hexo-html-minifier, 基于 HTMLMinifier
• hexo-clean-css, 基于 clean-css
• hexo-uglify, 基于 UglifyJS
• hexo-imagemin, 基于 imagemin

hexo-all-minifier 安装

在 hexo 目录中运行下面的命令

npm install hexo-all-minifier --save

在 hexo 配置文件中插入下面的代码

all_minifier: true

执行代码刷新，查看效果

hexo g
hexo d

hexo-all-minifier 配置
