├── webpack.config.js
└── package-lock.json

You can see above the basic structure of the boilerplate and the main differences with the official Jekyll folder structure


  • The required configurations are all in _config.yml
  • Also edit package.json the name is used in the meta tags
  • If you want a manifest.json file please edit config/manifest.json
  • Replace the different icon by yours in _images and in the root folder


  • SCSS partials should be located in _scss for better reading
  • Put all your images in _images the content of this folder will be moved to the _site/assets/images so you can access them with this path /assets/images/** in your templates, check the examples
  • Put all your Javascript files inside _src and import them from index.js or you can also add them as a new entry point in your webpack configuration file


  • All the posts should be there in inside _i18n folder inside its language, check the boilerplate examples
  • You can put your variables inside _i18n/en.yml (replace en with your language) and call them in your template with {% t variable_name.sub_variable %}
  • You can remove the plugin by removing gem 'jekyll-multiple-languages-plugin' from gemfile and jekyll-multiple-languages-plugin from plugins in _config.yml
  • We invite you to read the very good official documentation of the plugin Jekyll multiple language plugin


Optimized website

To build the website run the following line

npm run build

The built website will be in _site folder.

You can also run a local server to test it with this command

npm run serve:dist


If you want to build a PWA (including the manifest.json and the service worker) run the following. Please ensure to have configured this file config/manifest.json The built website will be in _site folder.

npm run build:pwa

Clean assets & _site folders

This will remove the generated folders

npm run clean:project

Known issues

  • Jekyll watch doesn't reload / rebuild when a translation file is updated inside _i18n folder, I recommand to remove jekyll-multiple-languages-plugin if you don't want a multi language website and if you want to watch / rebuild faster. Otherwise close and start npm run start to rebuild and see your changes from _i18n
  • Wsl2 requires to run sudo apt install -y build-essential libpng-dev in order to fix the pngquant failed to build, make sure that libpng-dev is installed issue
