[![lic-image]](LICENSE)

A hexo plugin that optimize the pages loading speed.

It will auto filter your html file, find the `` block and replace them into a javascript to [optimize CSS delivery](https://developers.google.com/speed/docs/insights/OptimizeCSSDelivery).

And inline the `main.css` into the html page like [@maple3142 does](https://github.com/maple3142/Blog/blob/master/gulpfile.js).

It will improve your pages loading and get a higher score in the [Google PageSpeed Insights](https://developers.google.com/speed/pagespeed/insights/).

**Known Issues:** This plugin may cause Font Awesome and PJAX to fail to load.

[![dt-image]][npm-url]

```bash
npm install hexo-filter-optimize
```

## Usage

Activate the plugin in hexo's `_config.yml` like this:
```yml
filter_optimize:
enable: true
# remove the surrounding comments in each of the bundled files
remove_comments: false
css:
# minify all css files
minify: true
# bundle loaded css files into one
bundle: true
# use a script block to load css elements dynamically
delivery: true
# make specific css content inline into the html page
# - only support the full path
# - default is ['css/main.css']
inlines:
excludes:
js:
# minify all js files
minify: true
# bundle loaded js files into one
bundle: true
excludes:
# set the priority of this plugin,
# lower means it will be executed first, default of Hexo is 10
priority: 12
```

This plugin can be disabled by `NODE_ENV` in development to boost `hexo generate`:
```
export NODE_ENV=development
```

## Comparison

Here is a [result](https://gtmetrix.com/compare/Z7BnLaPX/qSMKtzBY) from [GTmetrix](https://gtmetrix.com) 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 ...
