legacy babel-node has been removed - projet not working anymore!

I have this error when trying to launch npm start : "babel-node: not found"

The module has been replaced by https://github.com/npm/security-holdere, therefore you'll have to adapt your project or it won't fit the 'advanced redux' course anymore...

Start by reproducing the failure with npm start and tracing the start script's babel-node reference. Update the project for the replacement module, then verify that npm start launches the messenger service successfully and remains suitable for the Advanced Redux course.
