This came up in ember-auto-import, which uses this utility, but it's probably relevant to embroider too.
We use
packageName
to tests whether a given module specifier is trying to address an NPM package. It shouldn't treat!../../whatever!../stuff
as containing a package named!..
.I tried to use validate-npm-package-name for this, but it turns out a lot of very weird names are actually totally legal from its perspective, so I'm going with the more narrow case of identifying known prefix characters that webpack injects.
