npm is the package management tool for Node.js. Make sure it is installed. If it is not installed yet, run the following command in the terminal:

<code>npm install -g npm</code>

<code>node -v
npm -v</code>

Step 5: (Optional) Install Other tools

As needed, you can install other tools such as Yeoman, Webpack or ESLint. These tools can help you manage projects, build applications, or check for code errors.

Step 6: Create the project

Create a directory for the new Node.js project. Node.js applications and management packs can be run in this directory.

Step 7: Install packages

Use npm to install the packages required for the project. In the project directory, run the following command:

<code>npm install <package-name></code>

Step 8: Run the application
