To auto-reload a Node.js application using nodemon, you need to install nodemon as a development dependency of your project, and then configure it to run your application.

To install nodemon, open a terminal and navigate to the root directory of your project. Then, run the following command:

npm install --save-dev nodemon

This will install nodemon and add it to the devDependencies section of your package.json file.

Once nodemon is installed, you can configure it to run your application by adding a script to the scripts section of your package.json file.

For example, if your main file is called index.js, you can add the following script:

"scripts": {
  "start": "nodemon index.js"

Then, to start the auto-reloading server, you can run the following command:

npm start

This will start nodemon, which will run your application and automatically reload it whenever it detects changes to your code.

You can also pass additional options to nodemon by adding them after the script name. For example, you can use the --inspect option to enable the Node.js debugger, or the --watch option to specify a list of files or directories to watch for changes.
