We generally type following command for starting NodeJs server:
node server.js
In this case, if we make any changes to the project then we will have to restart the server by killing it using CTRL+C and then typing the same command again.
node server.js
It is a very hectic task for the development process.
Nodemon is a package for handling this restart process automatically when changes occur in the project file.
Installing nodemon: nodemon should be installed globally in our system:
Windows system: npm i nodemon -g Linux system: sudo npm i nodemon -g
Now, let’s check that nodemon has been installed properly to the system by typing the following command in terminal or command prompt:
nodemon -v
It will show the version of nodemon as shown in the below screenshot.
Starting node server with nodemon:
nodemon [Your node application]
Now, when we make changes to our nodejs application, the server automatically restarts by nodemon as shown in the below screenshot.
In this way with nodemon server automatically restarts.
