Create a nodemon.js file in your project folder, and add the following configuration.
mern-simplesetup/nodemon.js:
{ "verbose": false, "watch": [ "./server" ], "exec": "webpack --mode=development --config webpack.config.server.js && node ./dist/server.generated.js"}
This configuration will set up nodemon to watch for changes in the server files during development, then execute compile and build commands as necessary.
