The "npm:" import does not appear to have even started development, although it has been planned for a long time: https://github.com/denoland/deno/issues/13703

Core features for npm compatibility though (like implementing most of the npm api, including require(), and its special globals) has been making progress for a long time.

There is even a near complete project to support Node's native api (which bun also supports): https://github.com/denoland/deno/pull/13633

Relative to the the existing node compat efforts, the url import (and accompanying package download code) will be fairly small. The most difficult part is probably the extra stuff that node throws in the global namespace. How to handle that without having to pollute the global namespace for all programs (even those that do not import from node) is unclear.

Ideally these globals would be visible only from code in modules imported from npm. But the spec does not really allow for this unless the npm code is loaded in a different realm, but cross realm code causes a lot of headaches, which could only be avoided by having the realms share most globals and intrinsics (and sharing intrisics is not allowed by the spec).

There may be some other way to hack this into working, or perhaps programs with such imports that actually use NPM specific objects will need to be run with the "--compat" flag. It is really unclear at the moment.

The development is well under way, we expect to ship first iteration of this feature in the next release (v1.25) in the coming weeks.
