Do you have an example where version.matches("^[.~]*/.*") indicates a local node module is being used?

@jeremylong

I am using vaadin to build a web app and it automatically generates js files in the node_modules folder. It then puts the following local path in the package.json (without prefixing it with file:)

According to the npm docs, local paths can use four forms:

../foo/bar
~/foo/bar
./foo/bar
/foo/bar

Therefore, the regex ^[.~]*/.* matches all four of them:

Thanks for the detailed response! I made one very minor change to the regex (s/*/{0,2}/).

Great!
