How can i change database url (firebase real time db) in code? I would like to have option to choose which database you want (just different links)

You can have multiple firebase configs in an object like

var configs = {"option1":{},"option2":{}}

and then initialise them all with different names like

var databases = {}
Object.keys(configs).map((name)=>{
  const app = firebase.initializeApp(configs[name],name);
  databases[name]=app;
})

then based on the choice you can access the database and access the db and change the values etc

const app = databases["option1"]
//access the realtime db and so on
