Install nodemon as globally first, using these commands

`npm install -g nodemon` or `sudo npm install -g nodemon` 

Next, ensure the "scripts" field of package.json file as this type

"scripts": { "start":"nodemon index.js", "devStart": "nodemon index.js" } 

If not as this type then change it and run npm run devStart

For this firstly install nodemon globally as

npm install -g nodemon 

Now go to your express.js project directory and in that open the package.json file. In the package.json file change "start": "node ./bin/www" to "start": "nodemon ./bin/www"

Now run your app using npm start

First of all you need to install nodemon, so give root privilege and install globally using following command:

sudo npm install nodemon -g 

Then, go to your node project directory and open package.json and change "node" to "nodemon" in start field of scripts field.Ex:

"scripts": { "start": "nodemon ./bin/www" } 

Another solution: after install nodemon just run your app with nodemon start .

first of all, install Nodemon

npm i nodemon 

after this, go to package.json and add a new key/value into scripts, like this

 "scripts": { "dev": "nodemon src/index.js" }, 

so now just start you app with npm run dev
