# Additional Dependency Library Support

The difference with third-party support is that most of the functions here are implemented by installing plug-ins or introducing CDN, and are simply adapted by themes.

# Word Count

Install hexo-wordcount(opens new window)

npm install hexo-wordcount
# or
# yarn add hexo-wordcount

Enter the configuration file source/_data/yun.yml in the root directory of the blog

  • count: Word Count
  • time: Read Time
  enable: true
  count: true
  time: true


Install hexo-generator-feed(opens new window) .

npm install hexo-generator-feed --save

Configure the default icon as icon-rss-line. If you need to customize, enter source/_data /yun.yml to configure.

It can be configured in the social field of yun.yml, such as:

  - name: RSS
    link: /atom.xml # config.feed.path
    icon: icon-rss-line
    color: orange

For more configuration, please refer to Official Document(opens new window) (in _config.yml in the Hexo working directory).

# Sticky

Run the following command in the root directory of Hexo to remove the default index generator and use the sticky index generator.

The sticky feature of the original plugin has not been merged for a long time. # 26(opens new window)

npm uninstall hexo-generator-index --save
npm install hexo-generator-index-pin-top --save

You can reference hexo-generator-index-pin-top(opens new window) Note that when using hexo-generator-index-pin-top, the sorting function according to updated will be invalid. (The only way out is to wait for the official one to be merged.)

By setting the top property in the article Front Matter. After setting sticky, the sticky icon will appear in the upper right corner of the article card.

title: xxx
top: true

You can also set the level of priority to achieve the order of multiple sticky articles.

title: xxx
top: 1
title: xxx
top: 2

At this time, the articles of top: 2 will be arranged above the articles of top: 1.


You can also set the sorting according to updated, and then set the date of updated to a future date to achieve the sticky effect.

# live2d

There is no need to modify the theme to adding live2d, nor does it need to configure the theme. It is just a plug-in for Hexo. You can configure it in _config.yml in the root directory. The reason it appears here is to illustrate the recommended settings (in short, it is best to use CDN).

Install hexo-helper-live2d(opens new window)

npm install --save hexo-helper-live2d

Configure in _config.yml in Hexo root directory:

For more options, please refer to hexo-helper-live2d(opens new window)

  enable: true

  pluginRootPath: live2dw/

    opacity: 0.7
  # dialog:
  #   # whether to open the dialog box
  #   enable: true
  #   # whether to use hitokoto
  #   hitokoto: true

# Tag Cloud (Word Cloud)

Config in `yun.yml, use colorful word cloud instead of native tag cloud.

  • enable: enable word cloud
  • height: set height of word cloud

# player

# hexo-tag-aplayer(opens new window)

Install hexo-tag-aplayer(opens new window)

npm install hexo-tag-aplayer

See Official Document(opens new window)

Recommended configuration (in _config.yml in the root directory of Hexo):

  cdn: https://cdn.jsdelivr.net/npm/[email protected]/dist/APlayer.min.js
  style_cdn: https://cdn.jsdelivr.net/npm/[email protected]/dist/APlayer.min.css
  meting: true
  meting_cdn: https://cdn.jsdelivr.net/npm/[email protected]/dist/Meting.min.js


If you find that Aplayer sometimes introduces header files repeatedly in irrelevant files. Remember to turn off automatic script insertion.

Duplicate APlayer.JS loading(opens new window)

  asset_inject: false

Then decide at the head of the article whether to enable aplayer:


title: xxx
aplayer: true

You can also set it globally in yun.yml. (When you set up a global player, you can use it.)

  global: true

Insert a song from NetEase Cloud Music

{% meting "497572729" "netease" "song" "theme: # C20C0C"%}

# Global Music Player

You can set it global enable in yun.yml.

  • meting: enable meting(opens new window) , whether to introduce meting resources (pay attention to the difference between this and widget)
  • widget: set widget.enable true to enable global player (aplayer.global must be true)
    • meting.enable: whether to open meting for global widget. When open, it will load option; When close, will use cutsom audio.
    • audio: default config can be referred. More info see Official Documentation(opens new window)

Open pjax, it can realize that the music player is not interrupted when switching pages. (In order to load the music player correctly, when there is a music player in the article page that you switch to, Meting will reload.)

Since hexo-tag-aplayer is so fragrant, I decided to remove the original media package script. Students who are really in need can add it by themselves.

embeddedVideoTransformer: function () {
  let iframes = document.getElementsByTagName ("iframe");
  for (let i = 0; i <iframes.length; i ++) {

# KaTeX

Some simple mathematical formulas are shown in the article, using KaTeX. For details, please refer to Official Document(opens new window) .

  • copy_tex: copy katex text, enabled by default
  • global: If you want to use KaTex on the global page (such as the article summary on the homepage), then you can enable it. (Of course, this also means that your page needs to load more resources each time.)
  copy_tex: true
  global: false

KaTeX libraries will be loaded only in articles or pages that use katex, so you need to set them in articles or headers using KaTeX. (When you turn on global loading, you will no longer need to set this option.)


title: xxx
katex: true

You can wrap the formula in the following way.

In the following, the formula will be displayed in the center.

$$ E = mc^2 $$
\[ E = mc^2 \]

In the following, the formula will be displayed in line.

$E = mc^2$
\( E = mc^2 \)


Note that when writing directly in a Markdown file, you need an extra \ to translate \.

Use \\[E = mc ^ 2 \\] instead of \[E = mc ^ 2 \].

If you have too many characters that need to be translated, you can directly wrap it with HTML tags (internal characters will not be parsed as Markdown), without using multiple \ to translate. (Or use $E=mc^2$)

For example:

  \[E = mc ^ 2 \]

As shown below, the formula will be displayed in the center.

$$ E = mc ^ 2 $$
\[E = mc ^ 2 \]

As shown in the following package, the formula will be displayed in line.

\(E = mc ^ 2 \)

You can visit Yun Test(opens new window) to see the actual effect. You may need some time to wait for the KaTeX library to load, or refresh and try again.

# pjax

Use pjax(opens new window)

  enable: true

The following plug-in configuration and usage have nothing to do with the theme, you can refer to its documentation configuration yourself.

Because when you want some features that the theme does not provide, they can actually be implemented directly through plugins.

# hexo-blog-encrypt(opens new window)

You can use it to encrypt some private article pages.
