Firestore Example

// Initialize Firebase
import { initializeApp } from 'firebase/app';
import { getFirestore, collection, addDoc, query, where, getDocs } from 'firebase/firestore';

const app = initializeApp(firebaseConfig);
const db = getFirestore(app);

// Add document
await addDoc(collection(db, "users"), {
  name: "John Doe",
  email: "john@example.com",
  createdAt: new Date()
});

// Query documents
const q = query(collection(db, "users"), where("name", "==", "John Doe"));
const querySnapshot = await getDocs(q);
querySnapshot.forEach((doc) => {
  console.log(doc.id, doc.data());
});
