[Question] how to automatically get JavaScript source files by package.json file ?

Hi, I'm working on some TS/JS projects, and this tool really helped me, in the meantime I'm working with projects that may contain JS/TS or both of them, on that purpose I hope to find a way of getting JS files on project by passing the package.json path the same way as for tsconfig.json (I haven't found any function like addSourceFilesFromPackage as addSourceFilesFromTsConfig), currently I'm adding files using glob patterns.
