jekyll-tailwindcss

Jekyll plugin to use tailwindcss without node

Download

Jekyll::Tailwindcss

Bring the joy of building with TailwindCSS into your Jekyll project (without any JavaScript)

TL;DR This gem uses tailwindcss-ruby to provide platform-specific tailwind executables and enables a smooth developer experience in Jekyll projects

"Because building a great Jekyll site shouldn't require a node_modules folder"

Installation

Add the gem to your Jekyll project's Gemfile

# Gemfile
# ...
group :jekyll_plugins do
 # ...
 gem "jekyll-tailwindcss"
end

Run bundle install

[!TIP] By adding this gem to the :jekyll_plugins group, you don't need to explicitly configure it in _config.yml.

Optional: Choosing a specific version of tailwindcss

This gem uses the latest TailwindCSS by default. However since CLI versions are managed by the tailwindcss-ruby gem, it supports older versions as well.

You can use an older Tailwind version by specifying it in your Gemfile:

# Gemfile
# ...
group :jekyll_plugins do
 # ...
 gem "jekyll-tailwindcss"
end
# gem versions track against tailwind releases
gem "tailwindcss-ruby", "~> 3.4"
Tailwind Version 3 Setup

Tailwind V3 required a tailwind configuration file (tailwind.config.js), which needs to be specified in _config.yml:

tailwindcss:
  config: "./tailwind.config.js"

Tailwind will generate CSS for the classes found in content directories. For most Jekyll sites, this would work well.

// ./tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./_drafts/**/*.md",
    "./_includes/**/*.html",
    "./_layouts/**/*.html",
    "./_pages/*.{html,md}",
    "./_posts/*.md",
    "./*.{html,md}",
  ],
  // ...
};

Example CSS

Any CSS file with frontmatter and @tailwind directives will be converted.

/* assets/css/styles.css */
---
# This yaml frontmatter is required for Jekyll to process the file
---

@tailwind base;
@tailwind components;
@tailwind utilities;

.btn {
  @apply font-bold py-2 px-4 rounded !important;
}

will be converted to

/* _site/assets/css/styles.css */

/*
 * Tailwind generated CSS
 * ...
 */

PostCSS Support

[!WARNING] PostCSS configuration is considered an advanced use case and is outside the scope of this gem. It is possible that support be removed in future versions of this gem. If needed, you should look to run your Tailwind builds with node.

That said... This gem includes basic PostCSS support. If a postcss.config.js file is included in your _config.yml, the Tailwind CLI will be invoked with the --postcss flag.

Users should verify their PostCSS setup outside this gem by running: bundle exec tailwindcss --postcss postcss.config.js

tailwindcss:
  config: "./tailwind.config.js" # this is the default location
  postcss: "./postcss.config.js" # OPTIONAL, only if you have a postcss config file

Usage

See an example repo at https://github.com/vormwald/jekyll-blahg

Setup

You'll need 2 files to make this work:

File 1: ./_tailwind.css

This file acts as your tailwind configuration file. Import "tailwindcss" and any custom CSS here.

@import "tailwindcss";

/* ... any other imports or css classes */

File 2: ./assets/css/styles.tailwindcss

Place this file wherever you'd like your site's tailwind CLI generated content to go: assets/css/your_css_file.tailwindcss -> __site/assets/css/your_css_file.css

It must contain yaml frontmatter to be processed by Jekyll [^1]

---
# This file will be converted to __site/assets/css/styles.css
---
This file is just a placeholder. It's content will be replaced by output from the tailwindcss CLI.

[!NOTE] Why the 2 files?

This is a compromise to allow the TailwindCSS intellisense plugin to work. (It cannot parse a CSS file with frontmatter, so we keep it seperate)

The _tailwind.css file serves as the tailwindcss config file. If you'd rather set keep this file somewhere else, you can do so by setting the tailwindcss.config_file option in _config.yml:

tailwindcss:
  css_path: ./_data/tailwind.css

Building the Jekyll site

bundle exec jekyll serve

[^1]: Jekyll will process any file that begins with yaml frontmatter
