Module 4 Introduction

Module 3: Completed Code

In the last module, we configured our development environment to handle a client/server architecture and passed our Spotify auth token to our React app from our Node server with query params.

In this module, we'll learn how to store our Spotify access token in local storage so users don't have to go through the auth flow every time they visit our app. We'll also set up a way to automatically refresh the access token when it expires, without interrupting the user experience.
