You must make this change for the following videos to work correctly.

In the coming videos, I will show typing the characters rs at my terminal to restart the ts-node-dev instance.  The ts-node-dev library recently released a change that disables this restart behavior by default.  To enable it, you need to update the two scripts we added to the package.json file.  Update the two scripts to the following:

"scripts": {
  "publish": "ts-node-dev --rs --notify false src/publisher.ts",
  "listen": "ts-node-dev --rs --notify false src/listener.ts"
},

Just add in the --rs to each command.
