Exploring the Powerful Features of Eleventy (11ty)

As a UI designer who loves minimalist workflows and blazing-fast websites, Eleventy (also known as 11ty) has become one of my go-to tools for building static websites. It’s not just a static site generator — Eleventy’s power lies in its flexibility, speed, and ease of use. In this post, I’ll walk you through some of Eleventy’s standout features and why they’re so valuable for developers, designers, and content creators alike.

1. Simplicity and Flexibility

Eleventy doesn’t force you into a rigid structure or a specific JavaScript framework. It’s a zero-config, flexible framework that lets you work with the tools you already know and love. Whether you prefer Markdown, Liquid, Nunjucks, or other templating languages, Eleventy accommodates them all.

  • Template Flexibility: Use HTML, Markdown, Nunjucks, Liquid, Handlebars, or even JavaScript templates.
  • Customizability: Eleventy is highly customizable, letting you adjust build processes and configurations to your needs without any unnecessary bloat.

2. File-based Routing

One of the most intuitive features of Eleventy is its file-based routing system. The framework automatically generates URLs based on your folder structure and file names. No need to set up complex routing systems or configuration files — Eleventy does it for you.

  • Automatic URL generation: For example, a file located at /src/posts/my-first-post.md will automatically be available at /posts/my-first-post/ on the final site.
  • Clean URLs: No need for .html file extensions in your URLs. Eleventy strips them out, giving your site a clean and user-friendly URL structure.

3. Data Files for Dynamic Content

Eleventy shines when it comes to dynamic content. You can create and manage reusable data files in JSON, YAML, or JavaScript formats, and use them across your site. This is perfect for displaying lists, blog posts, or any other type of data that’s stored separately from your templates.

  • Centralized Data Storage: Store all your site’s content in data files (e.g., posts, metadata, navigation, etc.).
  • Customizable Data: Eleventy allows you to inject site-wide data into templates, making it easy to create dynamic layouts.

4. Template Inheritance

Eleventy makes it easy to create a consistent site layout through template inheritance. This feature allows you to create a base layout file (e.g., a general header, footer, and structure) and extend it in other templates, saving you time and effort in the design process.

  • Base Templates: Create a “master” layout that other pages inherit, so you don’t need to duplicate HTML code across your site.
  • Partial Templates: Use reusable components like headers, footers, or sidebars that can be included across different pages.

5. Incremental Builds

For large sites, Eleventy’s incremental builds feature is a game changer. It allows Eleventy to only rebuild the pages that have changed, rather than rebuilding the entire site. This dramatically speeds up the build process, especially on larger projects.

  • Speed Boost: Reduces build times by focusing only on modified content.
  • Efficient Development Workflow: Makes development more efficient by updating the site with minimal wait time.

6. Highly Configurable Build Process

Eleventy gives you full control over the build process, from customizing the input and output directories to adding custom filters or even creating new data files. You can also extend Eleventy’s capabilities with plugins.

  • Custom Filters: Add custom functions to manipulate your content, such as formatting dates, generating URLs, etc.
  • Plugin Support: Eleventy has an ecosystem of plugins for SEO, image optimization, markdown processing, and more. You can also build your own plugins if needed.

7. Support for Static & Dynamic Content

While Eleventy is primarily a static site generator, it doesn’t leave you high and dry if you need dynamic functionality. With its support for serverless functions (via integrations like Netlify Functions), you can add dynamic elements (like form submissions or API calls) to your otherwise static site.

  • Serverless Functions: Integrate dynamic features like contact forms, search functionality, or even a blog comment system.
  • Integration with Modern Tools: Seamlessly integrates with tools like Netlify, making it simple to deploy and extend with serverless features.

8. Preconfigured SEO and Performance Best Practices

Eleventy automatically helps you build SEO-friendly, fast-loading websites by following web best practices, such as generating clean, semantic HTML and automatically optimizing images. It also integrates easily with third-party services like Netlify, where you can enable advanced performance optimizations.

  • Image Optimization: Eleventy integrates with image optimization plugins that automatically resize and compress your images.
  • SEO-Friendly HTML: Built-in support for structured data and SEO best practices, including meta tags and sitemap generation.

9. Template and Asset Minification

Eleventy can automatically minify and optimize HTML, CSS, and JavaScript files during the build process, reducing page load times and improving the user experience. This helps ensure that your site is lightweight and performs well on both desktop and mobile devices.

  • Automatic Minification: Minify HTML, CSS, and JS files to reduce their size.
  • Optimize Assets: Minify and optimize assets to ensure that your site loads as quickly as possible.

10. Easy Deployment with Netlify

While Eleventy is all about static site generation, it pairs incredibly well with modern deployment platforms like Netlify. With one-click deployments, automatic builds, and continuous integration, Netlify takes care of deploying your Eleventy site without any hassle.

  • Automatic Builds: Whenever you push changes to your GitHub repository, Netlify automatically builds and deploys your Eleventy site.
  • Custom Domains and SSL: Easily set up custom domains, SSL certificates, and other advanced deployment features.

Conclusion

Eleventy’s simplicity, flexibility, and performance optimizations make it an ideal choice for anyone looking to create fast, clean, and efficient static websites. Whether you’re a designer, developer, or content creator, Eleventy provides the right tools to build exactly what you need without unnecessary complexity.

If you’re looking for a static site generator that offers complete control, speed, and easy configuration, Eleventy is an excellent choice. Plus, with its seamless integration with platforms like Netlify, you can deploy your site with just a few clicks!
