Eleventy v3.0.0: Possums ❤️ ESM Latest
Latest

We did it. After 22 pre-releases and over a year of work, Eleventy 3.0.0 is now available. You can try it out now on your project using:

npm install @11ty/eleventy@latest

If you’re upgrading from a previous version of Eleventy, use the Upgrade Help plugin for automated checks and help with your upgrade!

Why should you use Eleventy? Eleventy is a flexible and production-ready site generator known for its zero-client JavaScript footprint, speedy sites, speedy builds, and full control over the output.

A few numbers on the best version of Eleventy yet:

Stats v2.0.1 v3.0.0
20% smaller 35.2 MB 28.1 MB
11% fewer dependencies 213 189
9% faster npm install 4.511s* 4.103s*

*fastest time of 3 runs (bypassing local cache)

Flagship 3.0 features

  1. Eleventy is now written in ESM with full support for ESM in your projects: configuration, data files, 11ty.js templates, etc. For many projects this won’t be a breaking change and we’ll continue to support CommonJS too. Every example on the docs now includes both a CommonJS and ESM version. Docs: https://v3.11ty.dev/docs/cjs-esm/
// ESM
export default function(eleventyConfig) {}

// We’ll keep supporting CommonJS:
module.exports = function(eleventyConfig) {}
  1. Supporting more package managers and runtimes: pnpm, yarn, Deno. More examples on the docs! https://v3.11ty.dev/docs/
  2. Asynchronous configuration #614 Docs: https://v3.11ty.dev/docs/config/
// ESM
export default async function(eleventyConfig) {}

// CommonJS
module.exports = async function(eleventyConfig) {}
  1. For-free performance improvement to built-in slugify, inputPathToUrl universal filters (via memoization) #840 Docs: https://v3.11ty.dev/docs/memoize/

  eleventyConfig.setOutputDirectory("_site");
};

export const config = {
  dir: {
    input: ".",
    output: "_site"
  },
};
  1. Virtual Templates, configuration API to add content (great for plugins, used by the new RSS plugin!) #1612 Docs: https://v3.11ty.dev/docs/virtual-templates/
export default function(eleventyConfig) {
  eleventyConfig.addTemplate("robots.njk", "User-agent: *\nAllow: /", {
    permalink: "/robots.txt",
  });
};
  1. IdAttribute plugin adds id attributes to headings for on-page anchor links (supports all template-languages) #3363 Docs: https://v3.11ty.dev/docs/plugins/id-attribute/

  eleventyConfig.addBundle("css"); // Adds {% css %} paired shortcode to create per-page CSS bundles
};
  1. InputPath to URL plugin lets you link directly to an input file path (and we’ll output the right URL) Docs: https://www.11ty.dev/docs/plugins/inputpath-to-url/
<a href="my-template.md">Home</a> becomes <a href="/my-template/">Home</a>
  1. Use arbitrary JavaScript with the js Front Matter #2819 Docs: https://v3.11ty.dev/docs/data-frontmatter/#javascript-front-matter
---js
const hello = "hi";
---
{{ hello }}

  3. addDateParsing configuration API to add your own custom date parsing logic #867 Docs: https://v3.11ty.dev/docs/dates/#configuration-api-for-custom-date-parsing
  4. eleventyDataSchema data option to validate data cascade values #879 Docs: https://v3.11ty.dev/docs/data-validate/

Breaking Changes and Upgrade Path

Rather than navigating this list manually, use the Upgrade Help plugin for automated project checks and upgrade help!

  • Requires Node 18 or newer.
  • Removes Serverless and Edge plugins.
  • Use of bundled Eleventy plugins from CommonJS requires changing require("@11ty/eleventy") to await import("@11ty/eleventy") for ESM reasons. We provide helpful error messaging for this.
  • pug, ejs, haml, mustache, and handlebars plugins moved from core to official plugins
  • Throw errors if --config= command line file is missing #3373
  • The htmlOutputSuffix feature was removed #3327
  • Aliased custom templates must be declared in active formats #3302
  • --formats= and --formats="" on command line means no formats (previously aliased to *) #3255
  • Custom Template Language compileOptions.permalink option changed from true to "raw" #2780
  • Major semver updates of dependencies:
  • Full list of breaking changes

Minutiae

  • Packages are now published using npm package provenance.
  • The code base isn’t just ESM, it’s using tabs instead of spaces too 😱😈 #3098
