installing-a-dependency	Installing a Dependency

The generated project includes React and ReactDOM as dependencies. It also includes a set of scripts used by Create React App as a development dependency. You may install other dependencies (for example, React Router) with npm:

npm install --save react-router-dom

Alternatively you may use yarn:

yarn add react-router-dom

This works for any library, not just react-router-dom.
