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:

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
