NodeJS Auto-reload server

This document was migrated from DigiDocs

Problem: Manually reloading the NodeJS server by hitting Ctrl + C and entering npm start repeatedly in development is exhausting.

Solution: Automatically reload the server each time there is a change!

Nodemon#

Nodemon is a utility that will monitor for any changes in your source and automatically restart your server.

npm i -g nodemon

Install nodemon: npm i -g nodemon.
Replace node with nodemon in your command. For example, change node index.js to nodemon index.js. That's it.

You can also add it to npm scripts to make life even easier.

{
  "scripts": {
    "start": "node index.js",
    "dev": "nodemon index.js"
  },
}

After doing so, you can enter npm run dev subsequently, which will resolve to nodemon index.js.
