Takes your tree and checks for package.json in every folder and runs yarn in every folder.
You can add arguments when running the command
$ yarn-recursive --cmd upgrade
yarn upgrade v1.1.0
success All of your dependencies are up to date.
Done in 0.22s.
Current yarn path: YOUR_PATH/yarn-recursive/package.json...
End of yarns
$ yarn-recursive --cmd upgrade --opt <package-name>
If you want to skip the root directory of your project, add the --skipRoot option:
$ yarn-recursive --skipRoot --cmd test
This is useful if, for example, you want to run yarn-recursive from a script in your root package.json, which would otherwise cause infinite recursion.
