Jekyll::Gzip

Generate gzipped assets and files for your Jekyll site at build time.

Performance in web applications is important. You know that, which is why you have created a static site using Jekyll. But you want a bit more performance. You're serving your assets and files gzipped, but you're making your webserver do it?

Why not just generate those gzip files at build time? And with the maximum compression too?

Jekyll::Gzip does just that. Add the gem to your Jekyll application and when you build your site it will generate gzip files for all text based files (HTML, CSS, JavaScript, etc).

Installation

Add this line to your application's Gemfile:

gem 'jekyll-gzip'

And then execute:

bundle install

Usage

Once you have the gem installed, run bundle exec jekyll build. In your destination directory (_site by default) you will find gzipped files.

Serving pre-compiled gzip files

You will likely need to adjust your web server config to serve these precomputed gzip files. See below for common server configurations:

nginx

For nginx, you need to turn on the gzip_static module. Add the following in the relevant http, server or location block:

gzip_static on;

The ngx_http_gzip_static_module module is not built by default, so you may need to enable using the --with-http_gzip_static_module configuration parameter.

Other web servers

TODO: instructions for other web servers like Apache, HAProxy, etc.

Do you know how to do this for a different server? Please open a pull request or an issue with the details!

Development

After checking out the repo, run bundle install to install dependencies. Then, run bundle exec rspec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
