Netlify and Jekyll are a match made in static site heaven, but the real magic is how they democratize web publishing.
Let’s see it in action. Imagine you’ve got a blog powered by Jekyll. You write your posts in Markdown, Jekyll compiles them into static HTML, CSS, and JS files, and then Netlify takes those files and serves them to the world at lightning speed.
Here’s a typical Jekyll project structure:
my-jekyll-site/
├── _config.yml
├── _posts/
│ ├── 2023-10-27-my-first-post.md
│ └── 2023-10-28-another-post.md
├── assets/
│ ├── css/
│ │ └── style.css
│ └── js/
│ └── script.js
├── index.md
└── Gemfile
When you push this to a Git repository (like GitHub, GitLab, or Bitbucket), Netlify hooks in. It sees your .git directory, clones the repo, and then, based on your configuration, it knows how to build your site.
The core problem Jekyll and Netlify solve together is the complexity of dynamic web applications for content-heavy sites. Instead of managing servers, databases, and application runtimes, you just manage your content and code. Jekyll handles the "building" part, turning your source files into static assets. Netlify handles the "serving" part, making those assets available globally with incredible performance and reliability.
Here’s how the build process generally works on Netlify:
- Git Push: You commit your changes to your Git repository.
- Netlify Webhook: Netlify detects the push via a webhook.
- Build Environment: Netlify spins up a clean build environment.
- Dependency Installation: It installs your project’s dependencies. For Jekyll, this primarily means installing Ruby and the necessary gems specified in your
Gemfile. - Build Command Execution: Netlify runs your configured build command. For Jekyll, this is typically
bundle exec jekyll build. This command tells Jekyll to process your Markdown files, apply your theme, and generate the static_sitedirectory. - Deployment: Netlify takes the contents of the
_sitedirectory and deploys them to its global CDN.
To configure this on Netlify, you’ll go to your site’s settings and set the following:
- Build command:
bundle exec jekyll build - Publish directory:
_site
This tells Netlify exactly what to do. It knows to use bundle exec to ensure it’s running the Jekyll version specified in your Gemfile.lock, and it knows that the output of the build will be in the _site folder.
The levers you control are your Jekyll configuration (_config.yml), your content (_posts/, etc.), your theme, and any custom plugins you add. Netlify manages the rest: hosting, SSL certificates, continuous deployment, and even features like forms and functions if you need them.
The real power comes from the seamless integration of Git and Netlify. Every git push to your main branch automatically triggers a new build and deployment. If something goes wrong, you can easily revert to a previous commit. It’s a robust, scalable, and incredibly developer-friendly workflow for static websites.
The most surprising thing about this setup is how much Netlify abstracts away the underlying infrastructure while giving you granular control over the build process itself. You’re not just deploying files; you’re orchestrating a build pipeline.
One of the most impactful, yet often overlooked, aspects of Jekyll is its Liquid templating engine. You can embed complex logic directly within your static files. For instance, to display the current year in your footer dynamically, you wouldn’t hardcode 2023. Instead, you’d use {{ 'now' | date: "%Y" }} within your layout file. This means your static site can feel dynamic without sacrificing the performance benefits of static hosting, and Jekyll handles rendering this server-side (during the build) before Netlify serves the final HTML.
The next step in optimizing your Netlify + Jekyll workflow is exploring Netlify’s advanced features like deploy previews for pull requests or integrating Netlify Functions for serverless backend logic.
