Globbing

Use "globOptions" to customise how glob patterns match files. Refer to micromatch 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,

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,

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, 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.
