Hi @dgbeck,
In my Node.js app, I have a directory, let's call it myPage (src/node_modules/myModule/myPage) symlinked in src/pages/myPage, but _getMainPathsFromEntryPointArgument only allows vanilla directory bundling by checking fs.lstatSync( entryPoints ).isDirectory().
It would be nice to include support for symbolic linking in the condition e.g. isSymbolicLink().
