The ng add command in an Angular project is specifically designed to add a package or library while also configuring it adequately for the project. When you run this command, it not only installs the specified package but also takes care of all necessary configurations and adjustments needed for that package to function properly within your Angular application. This ensures that any required peer dependencies are installed, and it may also modify application files such as angular.json or environment files to seamlessly integrate the new functionality into your project.

This is a key distinction from other operations you might perform using Angular CLI commands, such as removing or updating packages, or listing installed packages, which have different commands and purposes. The ng add command streamlines the process of package integration—making it much easier for developers to enhance functionality without needing to manually handle configuration details.
