How to Deploy React JS Applications for Free on Firebase 2021

In this article , I’ll show you how to deploy react js applications for free on Firebase, First let’s understand what is Firebase

What is Firebase

Firebase is a Backend as a Service that started as a YC11 startup and grew up into a next-generation app-development platform on Google Cloud Platform. Firebase frees developers to focus crafting fantastic user experiences. You don’t need to manage servers. You don’t need to write APIs. Firebase is your server, your API and your datastore, all written so generically that you can modify it to suit most needs. Yeah, you’ll occasionally need to use other bits of the Google Cloud for your advanced applications. Firebase can’t be everything to everybody. But it gets pretty close.
