Big v3.0.0 Project Slipstream Changes

[zachleat]

Per feedback from the survey https://www.11ty.dev/blog/community-survey-results/ we’re making a few big changes in Eleventy v3.0.

• Requires Node 18+
• Working support for ESM Modify Eleventy to work with ECMAScript Modules (ESM) by default #836. To be clear, this adds ESM support to all JavaScript files:
  • Configuration Files
  • JavaScript Data Files (Global, Directory, or Template)
  • .11ty.js (and .11ty.mjs) Template Files
  • and importantly we will not require you to upgrade your projects to ESM either. Eleventy 3.0 will continue to support CommonJS Eleventy projects.
• Adds support for Async config (in both CommonJS and ESM) Allow configuration to return a promise (async-friendly) #614
• Removes Netlify-specific Serverless and Edge plugins as we rededicate to the Jamstack. You will still be able to run Eleventy in serverless environments, but Eleventy core will not manage this code. We’ll have some docs around this for the stable release.
• Removes pug, hbs, mustache, ejs, and haml from core. We are open to moving this code into plugins for the stable release, but please let us know! The survey indicated that these were the lowest priority template languages for most folks.

When is the release?

@mahnunchik Haven't heard much lately but it's probably going to be somewhat soon. The core team is small and does this pro-bono in their off-hours so it'll be ready when it's ready.

That said, 3.0.0-alpha.5 has been out for a while and although it's not tagged as a "stable" release, I (and I can only assume many others) have been running it in production for a few months now with very few issues. If you'd like to get up and running with the canary builds you can check out https://www.11ty.dev/blog/canary-eleventy-v3/ for instructions and a high-level overview of breaking changes. Hope this helps!

@noelforte thank you for the clarification.

I will try to use 3.0.0 alpha in one of new project 😉
