How to Install Nodemon as a DevDependency?

Nodemon is a development tool that is used to automatically restart your Node.js application when it detects changes to your code. You do not need to have Nodemon installed in production, as your application will be running continuously.

To install Nodemon as a development dependency, simply open a terminal window and navigate to the directory of your project and run one of the following commands:

npm install --save-dev nodemon
ORnpm i -D nodemon

This will install Nodemon and add it to your project's devDependencies section in the package.json file.

This means that Nodemon will only be installed in your project's node_modules directory if you are using a package manager, such as npm or Yarn. It will not be installed if you are deploying your project to production.

Once Nodemon is installed, you can start your Node.js application in development mode by running the following command:

nodemon

This will start Nodemon and watch for changes to your application files. When it detects a change, Nodemon will automatically restart your application.

This can be very useful for development, as it saves you from having to manually restart your application every time you make a change.

You can also use Nodemon to start specific scripts in your project. For example, if you have a script called server.js, you can start it in development mode by running the following command:

nodemon server.js

This will start Nodemon and watch for changes to the server.js file. When it detects a change, Nodemon will automatically restart the script.

Nodemon is a powerful tool that can help you save time and improve your development workflow. I highly recommend using it for all of your Node.js projects.
