const firebaseConfig = {

  authDomain: "YOUR_AUTH_DOMAIN",
  projectId: "YOUR_PROJECT_ID",
};

firebase.initializeApp(firebaseConfig);

const db = firebase.firestore();

const collectionRef = db.collection("your_collection");
const docRef = collectionRef.doc("your_document_id");

docRef.get().then((doc) => {
  if (doc.exists) {
    console.log("Document data:", doc.data());
  } else {
    console.log("No such document!");
  }
}).catch((error) => {
  console.log("Error getting document:", error);
});
