• Sass/Scss: Scss files are compiled before Eleventy builds the site. The files are compiled in the ./src/styles folder and then will be passed through copy (see .eleventy.js) to the new site created under ./dist/. For Netlify users, an alternative option with plugins is explained here: https://css-tricks.com/making-my-netlify-build-run-sass/.
• Critical CSS: Critical CSS is automatically included in the head of the document using the eleventy-critical-css plugin.
• PostCSS (Autoprefixer and PurgeCSS): Both dependencies have been set up to run through the main css stylesheet after Eleventy has generated the dist folder.
• Persistent dark mode using local storage as seen here: https://css-tricks.com/a-complete-guide-to-dark-mode-on-the-web/
• Cache busting via filter based on https://rob.cogit8.org/posts/2020-10-28-simple-11ty-cache-busting/.
• HTML minified on prooduction with https://www.npmjs.com/package/html-minifier package.
• PWA using https://github.com/okitavera/eleventy-plugin-pwa plugin.
• JS compilation and minification with Webpack CLI.
• Image processing with eleventy-img plugin. Generates multiple sizes images in two different formats (jpg and webp), and markup with <figure>, <picture> and native lazy loading.
• Modernizr CLI: To build a custom and minified version of the library as seen here: https://v2.14islands.com/blog/2016/04/20/better-way-to-use-modernizr-with-command-line-config/. Yetty is using it to detect if the browser supports Webp as background-image in CSS.

• Node.js v10 or higher must be installed to run this program.
• npm 7.20.0 or higher must be also installed.

git clone https://github.com/ygoex/yetty.git my-new-project

or, if you are currently signed in to GitHub, generate a repo from this template.

cd my-new-project

Specifically have a look at .eleventy.js to see if you want to configure any Eleventy options differently.

npm install

For local development:

npm start

To build a production version:

npm run build

For debug mode:

DEBUG=* npx eleventy

• about/index.md shows how to add a new content page.
• posts/ has the blog posts but really they can live in any directory. They need only the post tag to be added to this collection.
• Add the nav tag to add a template to the top level site navigation. For example, this is in use on index.njk and about/index.md.
• The blog post feed template is in feed/feed.njk. This is also a good example of using a global data files in that it uses _data/metadata.json.
• This example uses three layouts:
  • _includes/layouts/base.njk: the top level HTML structure
  • _includes/layouts/home.njk: the home page template (wrapped into base.njk)
  • _includes/layouts/post.njk: the blog post template (wrapped into base.njk)
• _includes/postlist.njk is a Nunjucks include and is a reusable component used to display a list of all the posts. index.njk has an example of how to use it.

• Inline CSS: If you require further control over the above the fold & common style inlined by CriticalCSS, you can inline the style manually as follows:

  1. Add the following code between the head tags in the base.njk file:

     {% set css %}
       {% include "inline_style/inline_style.css" %}
     {% endset %}
     <style>
       {{css | cssmin | safe}}
     </style>
     

  2. Create a scss file with the name inline_style.scss under _includes/inline_style/scss/inline_style.scss

  3. Add the following command to the beginning of the sass:prod script in package.json:

     node-sass src/_includes/inline_style/scss/ --output src/_includes/inline_style/ --output-style compressed &&
     

     And also, the following command to the beginning of the sass:dev script:

     node-sass src/_includes/inline_style/scss/ --output src/_includes/inline_style/ --source-map true --source-map-contents true &&
