hexo-yam

Yet Another Minifier for Hexo. Minify and compress HTML, JS, CSS and SVG. XML, JSON and many more are also compressed. Support gzip and brotli compressions.

Version 4

In v4, logger: option has been renamed to verbose:

Example:

minify:
  html:
    logger: true

needs to be updated to

minify:
  html:
    verbose: true

Installation

$ npm install hexo-yam --save

Options

minify:
  enable: true

enable - Enable the plugin. Defaults to true.

minify:
  html:
    enable: true
    exclude:

enable - Enable the plugin. Defaults to true.
priority - Plugin's priority. Defaults to 10. Set lower value to set higher priority and vice versa.
verbose - Verbose output. Defaults to false.
exclude - Exclude files.
- Support one-liner, exclude: [*.min.html, *.note.html].
- Test glob pattern on the web using Globtester.
globOptions - micromatch options to customise how glob patterns match files.
- Defaults to { basename: true }, unless the pattern has a slash.
  - basename is disabled depending on each pattern.
  - When specifying an array of patterns, e.g. exclude: ['*foo.html', '**/bar.html'], basename applies to '*foo.html', but not '**/bar.html'.
  - basename would stay disabled, if explicitly disabled in globOptions:.
  - However, basename option applies to all patterns in include:

HTTP Compression

While most modern web browsers support Brotli, you also need to consider whether the web/app server, hosting platform, reverse proxy or CDN (whichever relevant to you) support it.

As of May 2019, GitHub Pages, GitLab Pages and Netlify do not support brotli yet. You can generate .br files, but they won't serve those files.

Name	Status (May 8, 2019)
GitHub Pages	In consideration
GitLab Pages	In progress
Netlify	In consideration
Hexo Server	In progress

If you have access to the web server config, you should disable on-the-fly compression for static files (that are already compressed by this plugin),

nginx: Make sure both filter and static modules are enabled. This way pre-compressed .br files will be served while dynamic content can be compressed on-the-fly. Protip: brotli_types text/plain text/css application/javascript application/json image/svg+xml application/xml+rss; to prevent compressing media files (which are already compressed anyway).
Apache: See 'Serving pre-compressed content' section of mod_brotli.
Caddy: 0.9.4+ by default support pre-compressed .gz .br files and on-the-fly gzip compress dynamic files.
express/connect: Use pre-compressed-assets. You still can continue to use compression/shrink-ray-current for dynamic files.
