ANSWER Since the announcement of React Hooks, hundreds, if not thousands of articles, libraries, and video courses about them have been released. If you look carefully into the sea of resources, you'll find an article I wrote a while back that involved building a sample application using Hooks. You can find that article here.

Based on that article, a lot (two actually) of people asked questions related to how State can be managed in a React application using just Context and Hooks, which led to me doing a little research on the subject.

So for this article, we will be working with a pattern for managing state using two very important Hooks, useContext and useReducer, to build a simple music gallery app. The application will have only two views: one for login and the other to list the songs in that gallery.

The main reason for the login page is to show how we can share the Auth state across the application, which is a common use case for applications that use a library like Redux.

By the time we are done we should have an application that looks like the images below:
