Yet Another Minifier for Hexo. Minify and compress html, js and css. xml and json are compressed only. Support gzip and [brotli](https://en.wikipedia.org/wiki/Brotli) [compressions](https://en.wikipedia.org/wiki/HTTP_compression).

The original package has not been [updated](https://www.npmjs.com/package/hexo-neat) for a while. I update the [dependencies](https://github.com/weyusi/hexo-yam/blob/master/package.json) and add compression support.

All the options are the same, so you can use this as a drop-in replacement.

*Note:* See [HTTP Compression](#http-compression) section below for more info on using brotli.

## HTTP Compression
While most modern web browsers [support](https://www.caniuse.com/#feat=brotli) 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 2018, GitHub/GitLab Pages and Netlify *do not* support brotli. You can generate `.br` files, but they won't be serving those files.

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), e.g.

- [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.
- [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.
