I've seen a few node modules using require.extensions (such as js-yaml), but I haven't found it in the node docs. I'm checking here.
If this is a supported feature, then it should be documented. If it is undocumented because it was not meant to be documented, then perhaps it should be a read-only object (writable: false) instead.
I understand that no changes are being made to the module system at this time, but I think this should be documented.
Ya it should be documented. Patches welcome :)
Precisely because it's not going to change, yes. Patch welcome.
doc: add require.extensions to globals
Fixed in 718aa50.
