We never have any test case but seems everything's ok 😘

I wonder why replace cheerio with regex..?

[stevenjoezhang]

hexojs/hexo#3850

"dependencies": {
-    "cheerio": "0.22.0",
  },
  "devDependencies": {
+    "cheerio": "0.22.0",
  }

But... use regex to handle html? Why not just a use another html parser or similar tools such as jsdom or other lightweight alternative?
Regex shouldn't be used to parse html for any serious purpose.

Please note: Currently the theme is installed via git clone instead of npm install. Using any non-Hexo dependent package will get the same result: Error: Cannot find module xxx

另一个方案是，重写md渲染器
优点：更快
缺点：特定的功能模块只能使用内置的md渲染器，维护成本增加

比如：jiangtj/hexo-theme-cake#28 提供了disable_cake_marked禁用内置的md渲染，但禁用后，图片懒加载功能失效

维护一个主题已经很累了。渲染器不关我的事，谁爱管谁管。

😂 这几天在研究这个，hexo如果只用一个固定的md渲染器，整体性能应该能提高至少50%

确实如此，而且像 hexo-renderer-kramed 这种已经几年没更新了 https://www.npmjs.com/package/hexo-renderer-kramed 有兴趣的话可以发邮件给npm接手这个包。
如果Hexo的渲染器有插件的接口，并且给主题调用的方法，那么就可以高效地解决问题。但这还没有被纳入Hexo的标准，有兴趣的话可以向Hexo提一下建议。
