In this React 16+ tutorial, we are going to integrate Firebase Database service and Material UI library to create a working TODO application having CRUD (Create Read Update and Delete) operations in React Js application. Users can Add, List, Update or Delete todos from a list by communicating with Firebase. Firebase is very popular for many cloud-based services like Realtime database, Authentication services, Testing, Storage, Crash analysis, Hosting, and many more. The combination of React and Firebase can move applications to the next level. In this tutorial, we are going to integrate Firebase NoSQL Database service using which a user can do CRUD operations realtime in the application.

It is a very popular React specific UI library to add beautifully designed components like Inputs, Buttons, Modal, Grids, Lists, Icons, etc very quickly.
