Environments in Jekyll

Jekyll is a simple, blog-aware, static site generator perfect for personal, project, or organization sites. Jekyll takes your content, renders Markdown and Liquid templates, and spits out a complete, static website ready to be served by Apache, Nginx or another web server.

In the build (or serve) arguments, you can specify a Jekyll environment and value. The build will then apply this value in any conditional statements in your content. For example, if you need to separate production from development (for example comments), you can use liquid variable jekyll.environment which can be exported or used inline with JEKYLL_ENV=development jekyll serve --watch.

Example:

{% if jekyll.environment == "production" %}
  <script>
    // JavaScript snippet...
  </script>
{% endif %}

When you build your Jekyll site, the content inside the if statement won’t be run unless you also specify a production environment in the build command.
