Third party packages, libraries and/or plugins can easily be added to the pattern library for additional features and functionality.
New packages can be added to your project by running npm install example-package --save-dev.
This command does the following:
installs example-package into the node_modules directory at the project root.
saves example-package as a project dependency in package.json
After installation you will need to follow the directions for each package in order to set up within your project. These can usually be found in the package's README file.
