    >Does this mean that in theory i could skip the build/bundling step entirely?

    You can but you must write your app in something the browser understands (js not ts, css not sass etc) and use native modules. For example, here is the test harness for a custom module, written in pure html with no build step: https://github.com/javajosh/simpatico/blob/master/combine2.h.... Here is a more complex (and much older) example from Crockford: https://www.jslint.com/

    And yes, the experience developing this way is quite nice!

    *>...use types [at] runtime..."

    Two things. First, TS conceives of itself as having no runtime component. If it did, I think people (including the TS devs) would be more confused.

    Second, I'd say rather we need a runtime type system. In fact I've tried my hand at writing one in the most minimalist way possible, and have been working on it recently [1]. The type system is explicit in that a type is a JSON like object, similar to JSON schema, but 100x less code.

    [1] https://github.com/javajosh/simpatico/blob/master/friendly.h... This is effectively the test harness for the module.

    This downloads the ESM version of Observable Plot from the jsDelivr CDN, figures out its dependencies, downloads them as well (40 files total!) and rewrites their imports to be local, not CDN paths.

    More details here: https://simonwillison.net/2023/May/2/download-esm/

    I'm not considering adding import maps support: https://github.com/simonw/download-esm/issues/4
