## Overview

This repository is an Auth0 React quickstart sample. A user enters the browser app, uses Auth0-backed login, navigates to a profile or protected API example, and can send an access-token-bearing request to the local API. The graph also includes the home-page guidance and profile display. The API server's implementation was not sampled, so its internal behavior is not expanded; its validation role is documented by the API view.

Main entry points: [`Sample-01/src/App.jsx`](https://github.com/auth0-samples/auth0-react-samples/blob/master/Sample-01/src/App.jsx) (App routes), [`Sample-01/src/views/ExternalApi.jsx`](https://github.com/auth0-samples/auth0-react-samples/blob/master/Sample-01/src/views/ExternalApi.jsx) (External API view), [`Sample-01/src/index.jsx`](https://github.com/auth0-samples/auth0-react-samples/blob/master/Sample-01/src/index.jsx) (Browser bootstrap), [`Sample-01/src/views/Home.jsx`](https://github.com/auth0-samples/auth0-react-samples/blob/master/Sample-01/src/views/Home.jsx) (Home view)
