Use ESM-only version of `luxon` (our biggest dep at 4.6 MB)

[zachleat]

luxon includes 4 different versions of compiled code in the build

It’d be nice to have an ES6-only version of luxon.

I'm thinking luxon as a dependency could be removed entirely, along with some of the other large dependencies (nunjucks at 1.8MB, liquidjs at 1.7MB, even markdown-it at 767KB). Luxon is only used for content date parsing, and might be better suited as a plugin (@11ty/eleventy-plugin-dates?). Additionally, like the more esoteric templating languages that were moved out of core to plugins with v3, Nunjucks and Liquid should also be plugins - so that I, someone who uses neither of those two (I use Vento), am not installing an extra 3MB every time.

Do you mind to open a new issue regarding this?

(I'm using Nunjucks and feel the support for different template languages is something that contributes to Eleventy's uniqueness - but this discussion is better held in a new issue).

Multi-export CJS/ESM luxon caused a bug! #3674

Probably a year or two away yet but the long term vision will likely be to use the Temporal API instead of luxon, eventually! https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal
