Yet Another Minifier for Hexo. Minify and compress HTML, JS, CSS, SVG, XML and JSON. [Other files](https://github.com/curbengh/hexo-yam/blob/ba77db0094a7c07ea9f70f010bfc15541d4105ca/index.js#L64) are also compressed. Support gzip and [brotli](https://en.wikipedia.org/wiki/Brotli) [compressions](https://en.wikipedia.org/wiki/HTTP_compression).

## Version 6
|
|
In v6, `svg.plugins:` option should be the following syntax:
|
|
|
|
``` diff
|
|
minify:
|
|
svg:
|
|
plugins:
|
|
# v6
|
|
+ removeComments: false
|
|
+ cleanupIDs: false
|
|
+ builtinPluginName:
|
|
+ optionName: 'optionValue'
|
|
|
|
# v5
|
|
- - name: 'removeComments'
|
|
- active: false
|
|
- - name: 'cleanupIDs'
|
|
- active: false
|
|
|
|
# v4
|
|
- - removeComments: false
|
|
- - cleanupIDs: false
|
|
```
|
|
|
|
The option only overrides svgo's default plugins, other options are not supported.

|
|

|
## Globbing
|
|
|
|
Use "globOptions" to customise how glob patterns match files. Refer to [micromatch](https://github.com/micromatch/micromatch#options) for available options.
|
|
|
|
- basename is enabled by default, unless the pattern has a slash.
|
|
- basename is disabled depending on each pattern.
|
|
- This means the following options would work,
|
|
|
|
``` yml
|
|
exclude:
|
|
- '*foo.html' # basename is enabled
|
|
- '**/bar/*/*.html' # basename is automatically disabled
|
|
- '*baz.css' # basename is enabled
|
|
globOptions:
|
|
basename: true # default
|
|
```
|
|
|
|
- This behaviour doesn't apply to pattern that starts with `!` (negation).
|
|
- This limitation only applies to `include:` option used in svg, gzip and brotli.
|
|
- This means the following options would *not* work,
|
|
|
|
``` yml
|
|
include:
|
|
- '!foo.svg'
|
|
- '!**/bar/*/*.svg'
|
|
globOptions:
|
|
basename: true
|
|
```
|
|
|
|
- basename will stay disabled, if explicitly disabled in "globOptions".
|
|
|
|
|
|
## HTTP Compression
|
|
|
|
While most modern web browsers [support Brotli](https://www.caniuse.com/#feat=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 Sep 2020, GitHub Pages and GitLab Pages *do not* support brotli yet. You can generate `.br` files, but they won't serve those files.
|
|
|
|
Name | Brotli support
|
|
--- | ---
|
|
GitHub Pages | [In consideration](https://github.community/t5/GitHub-Pages/Support-for-pre-compressed-assets-and-brotli-compression/m-p/22055)
|
|
GitLab Pages | Yes
|
|
Netlify | Yes
|
|
Hexo Server | [In progress](https://github.com/hexojs/hexo-server/pull/100)
|
|
|
|
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](https://github.com/google/ngx_brotli): 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](https://httpd.apache.org/docs/2.4/en/mod/mod_brotli.html): See 'Serving pre-compressed content' section of [mod_brotli](https://httpd.apache.org/docs/2.4/en/mod/mod_brotli.html).
|
|
- [Caddy](https://caddyserver.com/features): [0.9.4+](https://caddyserver.com/blog/caddy-0_9_4-released) by default support pre-compressed `.gz` `.br` files and on-the-fly gzip compress dynamic files. v2 requires [manual configuration](https://mdleom.com/blog/2020/11/12/caddy2-pre-compressed/), serving them automatically to be supported [in future](https://github.com/caddyserver/caddy/issues/2665).
|
|
- [express](https://github.com/expressjs/express)/[connect](https://github.com/senchalabs/connect): Use [pre-compressed-assets](https://github.com/domadams/pre-compressed-assets). You still can continue to use [compression](https://github.com/expressjs/compression)/[shrink-ray-current](https://github.com/Alorel/shrink-ray) for dynamic files.
