There is a standard Auth0 JavaScript library for single-page applications that we can leverage that will interact nicely with Auth0. The npm package for the library is called @auth0/auth0-spa-js. Let's install this by running the following command in the Visual Studio Code Terminal:

> npm install @auth0/auth0-spa-js

TypeScript types are included in this library, so the Auth0 client library for single-page applications is now installed into our project.
