And I’m using expo bundler . This is my project structure . In the backend folder I want to create an express server for post , get , put ,etc.. requests . I want my data to be use firestore as the database . I don’t want my server to be app specific , it take the request coming from the android or ios mobile app and from a web app also . I have created a firebase project . In that I’m getting three option Ios , android or web , which I should choose to configure my app to ? Do I need to configure firebase for ios or android to my react native application , since I’m connecting firebase to node.js and creating a server and making api calls to fetch data from the database ? Below are the Images attached. Firebase config options .
