To my knowledge what node implements is nearly a superset of CommonJS. It is true that a pure CommonJS implementation cannot handle many node packages due to additional features that node has added to the module descriptor, or due to use of node specific built-in packages/globals/extra properties on require, etc. But I was under the impression that node could generally import and handle strictly conformant CommonJS packages just fine in practice. Of course, I won't argue that many npm packages not being conformant CommonJS packages makes things difficult for non-node server-side javascript environments, since they either need to add additional node compatibility, or might need their own package repository.
