Jekyll::Webpack

This plugin will allow you to build your assets with Webpack after Jekyll has compiled your site to the _site folder. You will need to have Webpack installed at the root of your project in order for this to work.

Why?

This adds Webpack at a sane point in the build pipeline and will also allow you to parameterize your webpack and other JS config files by prepending them with front matter, before the compilation occurs. You can see a functioning example in the spec/fixtures folder:-

Installation

Add this line to your application's Gemfile:

gem 'jekyll-webpack'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install jekyll-webpack

And add the following to your site's _config.yml

plugins:
  - jekyll/webpack

NOTE the / - the - variant is not available yet.

ALSO NOTE - it's probably advisable to place this plugin as the very last one in the build pipe. EG:-

plugins:
  - jekyll-otherplug
  ...
  - jekyll/webpack

Usage

In your root Jekyll project folder you need to have Webpack installed, so:-

yarn add webpack webpack-cli --dev

And the basic JS entrypoint mkdir src && touch src/index.js

And you're away! Just run the jekyll serve or jekyll build commands with whatever env you need.

Config

Configuring JS config files

There is a _data/tailwind.yml file in the fixure site that's picked up by adding a frontmatter declaration in tailwind.config.js. This Tailwind config is in turn picked up by the outputted webpack config and parsed when webpack runs.

Debouncing Webpack runs

Sometimes the webpack build can take a long time. You can configure jekyll-webpack to debounce the build in a number of ways. The options are:-

  • run once (when you first run serve)
  • run every n iterations (specify a number of iterations to skip webpack compilation)
  • run on watch folder changes (specific a folder to watch and only run webpack when a file in the folder has changed)

Add the following entries into _config.yml

// _config.yml

webpack:
  debounce:
    run_once: true

// or ...
webpack:
  debounce:
    every: 10

// or ...
webpack:
  debounce:
    watch: src

This is very useful if you plan to use jekyll serve with the --livereload option as it can speed up your development time significantly.

Cleanup

If you wish to clean out unused source files after webpack has run that got included in the compiled site, you need to add an entry into your _config.yml like:

// _config.yml

webpack:
  cleanup_files: src

// or an array

webpack:
  cleanup_files:
    - src
    - node_modules

Dest inclusion (excluding

If want to ensure that webpack only runs in a specific site dest (eg _site only, and no subdirectories) you can pass a single path value or an inclusion list of paths you want webpack to run in, at config time, by modifiying the _config.yml like so:

// _config.yml

webpack:
  only_in: _site

// or as a list
webpack:
  only_in:
    - _site
    - _build

Example _config.yml

You can have a look at the possible configuration options in the fixtures config file at spec/fixtures/_config.yml in this repo.

Development

After checking out the repo, run bin/setup to install dependencies. Then cd spec/fixtures && yarn to install required JS dependencies for specs. Then, run rake spec 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.
