Feature request: Resolve bare module specifiers in JS modules

[justinfagnani]

This dev server would be a lot more useful for projects with client-side JS if it could resolve bare module specifiers so that they load correctly in browsers.

It's not too terribly complicated to do this with middleware and a dependency on something like enhanced-resolve. Here's a single-file implementation in my own server framework that could be adopted: https://github.com/justinfagnani/zipadee/blob/main/packages/javascript/src/lib/serve.ts

I think the biggest question I’d have here is that if we added resolution for this stuff, this creates a dev-server/build discrepancy, no? It’d work nicely in the dev server, but would be “broken” in the full static build (without additional work)

The thing about module resolution is that so many tools do it, so you'd have your choice of how to handle this in non-dev. The 11ty rollup plugin would pair very nicely with this.
