A plugin for integrating imgix into Jekyll sites
Ruby 46 16 days ago imgix/jekyll-imgix

Installation

First, add liquid and jekyll-imgix to the :jekyll_plugins group in your Gemfile:

group :jekyll_plugins do
  gem 'rouge'
  gem 'kramdown'
  gem 'liquid'
  gem 'jekyll-imgix'
end

Then include jekyll-imgix in the plugins: section of your _config.yml file:

plugins: [jekyll/imgix]

Configuration

jekyll-imgix requires a configuration block in your _config.yml:

imgix:
  source: assets.imgix.net # Your imgix source address
  secure_url_token: FACEBEEF12 # (optional) The Secure URL Token associated with your source
  include_library_param: true  # (optional) If `true` all the URLs will include `ixlib` parameter

Multi-source configuration

In addition to the standard configuration flags, the following options can be used to serve images across different sources.

imgix:
  sources:  # imgix source-secure_url_token key-value pairs.
    assets.imgix.net: FACEBEEF12
    assets2.imgix.net:            # Will generate unsigned URLs
  default_source: assets.imgix.net  # (optional) specify a default source for generating URLs.

Note: sources and source cannot be used together.

Usage

jekyll-imgix does not do anything unless JEKYLL_ENV is set to production. For example, you will want to run JEKYLL_ENV=production jekyll build before deploying your site to production.

jekyll-imgix exposes its functionality as a single Jekyll Filter, imgix_url.

Pass an existing image path to it to activate it:

<img src={{ "/images/bear.jpg" | imgix_url }} />

That will generate the following HTML in your output:

<img src="https://assets.imgix.net/images/bear.jpg" />

You can also pass parameters to the imgix_url helper like so:

<img src={{ "/images/bear.jpg" | imgix_url: w: 400, h: 300 }} />

Which would result in the following HTML:

<img src="https://assets.imgix.net/images/bear.jpg?w=400&h=300" />

Multi-source usage

To use jekyll-imgix in a multi-source setup:

<img src={{ "/images/bear.jpg" | imgix_url: "assets2.imgix.net", w: 400, h: 300 }} />
<img src={{ "/images/bear.jpg" | imgix_url: w: 400, h: 300 }} />  <!-- will use default_source from config -->

Which would generate:

<img src="https://assets2.imgix.net/images/bear.jpg?w=400&h=300" />
<img src="https://assets.imgix.net/images/bear.jpg?w=400&h=300" />

In absence of correctly configured default_source, imgix_url will report RuntimeError if it's used without specifying a valid source.
