Crom – A package manager without the package registry

As far as I know there are channels with nix-expressions (which are the package definitions), which are descriptions of how gather the source-code or binaries from specific URLs.

npm2nix for example only uses npm to gather the the packages from the registry, but uses Nix for all the other stuff. [0]

It’s hard to tell how much overlap there is.

One of way of looking at Crom is that it provides a more convenient interface than a URL, yet without the centralization that comes from using names in a registry.

Crom helps you go from a name to a URL (via search heuristics), but it’s the URL that ultimately serves as the identifier. So, if you author a package.json with a name like “d3-format”, that gets expanded to a full URL, perhaps with interactive confirmation. (Or not, because it’s trivial to undo and redo.)

Also, unlike a URL to the ZIP file directly, a package URL in Crom supports semantic versioning: it refers to all versions of a project, and thus you can upgrade or specify a desired version range.
