For packages like @feathersjs/transport-commons, adapter-commons or even @feathersjs/feathers on npmjs.com I had trouble to find the corresponding folder in this monorepo. package.json allows a repository.directory property to define the subdirectory in a mono-repo. By doing that, the click on the repository on npmjs.com lead directly to the sub directory of the package. On https://www.npmjs.com/package/@feathersjs/adapter-commons it's even worse because it leads to https://github.com/feathersjs/databases...

npm docs say:

If the package.json for your package is not in the root directory (for example if it is part of a monorepo), you can specify the directory in which it lives:

{
  "repository": {
    "type": "git",
    "url": "https://github.com/facebook/react.git",
    "directory": "packages/react-dom"
  }
}

So, the repository url on each @feathersjs/... package leads to the subdirectory of the github repo.
