Lecture 238:- Nodemon, Automatic Server Restarts

Nodemon is a utility tool that monitors the file changes in your application and automatically restarts the server when a change is detected. This saves the developer from manually stopping and restarting the server every time they make a change to the code.

To use nodemon, you first need to install it globally using the Node Package Manager (npm) by running the following command:

Copy code

npm install -g nodemon

Once nodemon is installed, you can use it to start your Node.js application by running the following command:

Copy code

nodemon app.js

This command will start your Node.js application and watch for file changes in the current directory. If any changes are detected, nodemon will automatically restart the server.

You can also pass additional options to nodemon using the command line arguments. For example, to watch for changes in a specific directory, you can run the following command:

cssCopy code

nodemon --watch /path/to/directory app.js

This will start nodemon and watch for changes in the /path/to/directory directory.

Using nodemon is a good practice in Node.js development as it helps to increase productivity and reduces the time required for manual server restarts.
