Today I learned… that you don’t have to navigate to Terminal, press CTRL + C to stop the server, and re-enter node server.js to start up the express server again in order to see your latest work in the browser.
There’s a better way: get Nodemon and automate this repetitive process!
Nodemon will watch the files in the directory you run it in and restart your server automatically when it detects a change.
To install Nodemon:
$ npm -g install nodemon
To get Nodemon running:
$ nodemon server.js
Leave that Terminal window open and let Nodemon work its magic.
