Key Differences between Eleventy (11ty) and Astro

When you rebuild your Eleventy (11ty) site in Astro, you will notice some important differences:

Eleventy supports a variety of templating languages. Astro supports including components from several popular JS Frameworks (e.g. React, Svelte, Vue, Solid), but uses Astro layouts, pages and components for most page templating.
Astro uses a src/ directory for all files, including site metadata, that are available for querying and processing during site build. Within this is a special src/pages/ folder for file-based routing.
Astro uses a public/ folder for static assets that do not need to be processed nor transformed during the build.
In Eleventy, bundling CSS, JavaScript, and other assets needs to be configured manually. Astro handles this for you out-of-the-box.

Your Eleventy project allowed you to use a variety of templating languages to build your site. In an Astro project, your page templating will mostly be achieved with Astro components, which can be used as UI elements, layouts and even full pages. You may want to explore Astro’s component syntax to see how to template in Astro using components.

To convert other types of sites, such as a portfolio or documentation site, see more official starter templates on astro.new.
