# nodejs

Node.js and npm as a module (novox/hq ADR 0477 §4, issue 1573).

- **Owns the packages `nodejs` and `npm`.** No other module declares them (`checks/toolchains` refuses one that
  does).
- **Provides `node-toolchain` with the machine's reach**: dev-tools, lab and mesh-build-node require it, and the
  requirement is met only by this module on the same machine. It is never pulled in for whatever asked, so
  `nodejs` is assigned to a node on purpose, and a node without it refuses a module that needs it at resolution.
- Holds no long-running resource, so it adds nothing to `health-undeclared`.

The node-engine never uninstalls a package, so moving the declaration here removes nothing from a node.
