VisualizaçõesHow can I display data from Firebase database?
In the application, you can add your bank to the Firebase database. When you click on the "Add Bank" button, the bank is saved to the database. I need to display cards with added banks on the screen. How can i do this? Now I am reading data from the database and it comes in the form of an object:
Code for read data:
const getBanksFunc = () => {
const bankRef = ref(database, "banks/");
onValue(bankRef, (snapshot) => {
const data = snapshot.val();
});
};

Firebase's documentation covers this:
https://firebase.google.com/docs/database/web/read-and-write
import { getDatabase, ref, onValue} from "firebase/database";
const db = getDatabase();
const starCountRef = ref(db, 'posts/' + postId + '/starCount');
onValue(starCountRef, (snapshot) => {
const data = snapshot.val();
updateStarCount(postElement, data);
});
In your case, a for .. in loop could work:
for(let key in data) {
const { bankName, interestRate, loanTerm, maximumLoan, minimumDownPayment } = data[key];
... do whatever you need
}
