Tips

Debugging with Node.js inspector

Node.js's built-in inspector (node --inspect) works great for debugging Node.js with Chrome DevTools. Nodemon however restarts our Node.js server on every code change creating a new URL for debugging. To have your DevTools automatically reconnect with your new app you can use the NIM (Node Inspector Manager) Chrome extension.
