how to install node js dependencies from package.json

1. Open a terminal or command prompt.

2. Navigate to the root directory of your Node.js project using the cd command.

3. Run the following command to install the dependencies listed in your package.json file:

bash npm install

This command reads the dependencies from the package.json file and installs them in the node_modules directory.

1. Wait for the installation process to complete. npm will display progress messages and a summary of the installed packages.

Note: You can add the -g flag after npm install to install the packages globally if they are intended for global use.

That's it! Your Node.js project's dependencies are now installed and ready to use.
