Today we'll be adding authentication (via Google Authentication and Firebase) to our Fun Food Friends app, so that only users that are signed in can view who is bringing what to the potluck, as well as be able to contribute their own items. When users are not signed in, they will be unable to see what people are bringing to the potluck, nor will they be able to add their own items.
Let's take a look at building something using Firebase and React. We'll be building something called Fun Food Friends, a web application for planning your next potluck, which hopefully feels like something rather "real world", in that you can imagine using these technologies in your own production projects. The big idea in this app is that you and your friends will be able to log in and be able to see and post information about what you're planning to bring to the potlock.
