lib: domin some circumstance https://twitter.com/_brotzky/status/1016915341694255104?s=19Wesley Wigham (@weswigham) it will be nice to try to get this in sooner than 3.1 if we can.
Possibly some common NodeJS imports:
EventEmitter,Readable,Writable,fs(add a namespace import for "fs" module),path(namespace import for "path" module).In the vein of
pathandfs, possibly suggestions for module names we can detect. For example, if you have the "vinyl" package and referencevinylwithout an import, we could suggest the namespace import.For things like
EventEmitter, if we know that type exists in a module not imported, we could suggest the import (similar to how we already have a quick fix).- locked as resolved and limited conversation to collaborators
