All the data is store in Firebase Realtime Database and Firestore database.

In Firebase we store the informations about the app, like colors, navigation etc..

And in Firestore is where our actual data is. Like menu content, categories, orders etc..

We use Firebase because it has import function. 

Let's get started.  Create an account in Firebase with your google account. 

Create Firebase Project. 

Then go in Project settings, and click on "Add Firebase to your web app"

Then copy the config string. 

Then in your react native project, in root folder there is "config.js" file.  At start replace the config for firebase there.

You mobile app is set up now and connected to Firebase.
