A hexo plugin that optimize the pages loading speed.
It will automatically filter your html file, find the tag and make optimizations on demand, for example:
- Inline the main.css into the html page, to speed up your site's First Contentful Paint. (Useful when HTTP/2 Server Push is not available on your web server)
- Load CSS asynchronously or deferred.
It will help you get a higher score in the Google PageSpeed Insights.

Here is a result from GTmetrix to show you the changes between before and after. (Same web server located in Tokyo, Japan, vultr.com)
* Remove query strings from static resources - let all the proxies could cache resources well. (https://gtmetrix.com/remove-query-strings-from-static-resources.html)
* Make fewer HTTP requests - through combined the loaded js files into the one.
* Prefer asynchronous resources - change the css delivery method using a script block instead of link tag.
* And TODOs ...
