App is not updating when I save changes to app.js NodeJs

Question

I'm building my first NodeJs app, and I was hoping that the browser would update whenever I hit Control+S on my app.js file. For example, initially I have it outputting Hello world, then I do node app.js, visit http://localhost:3000 in my browser. If I go back to editing app.js and update it to be Hello world2, I have to cancel node via Control+C, then node app.js to see my updates. Not even doing F5 in my browser will get the latest changes.

You can use Nodemon to auto-restart your server when files are changed

Install:

npm install -g nodemon

Run:

nodemon ./server.js localhost 3000
