VisualizaçõesFirebase get data from Firestore v9 react
I am trying to get order details from firestore using following function. But here it does not send any response back and shows that docSnap.data() is not a function
My data base structure is - User/userid/orders/data
How can i get data as response without any error?
Here is my code below -
import React, { useState, useEffect } from "react";
import { db } from "./firebase";
import { collection, doc, getDoc, orderBy } from "firebase/firestore";
import "./Orders.css";
import { useStateValue } from "./StateProvider";
const Orders = () => {
const [{ basket, user }, dispatch] = useStateValue();
const [orders, setOrders] = useState([]);
useEffect(async () => {
console.log(user?.uid);
try {
const docRef = doc(db, `${user?.uid}/orders/`);
const docSnap = await getDoc(docRef);
console.log(docSnap);
} catch (e) {
console.log(e);
}
}, []);
return (
<div className="orders">
<h1>orders here</h1>
</div>
);
};
export default Orders;
Here is the entire path to the document which i expect funtion to read.

If db is a FirebaseFirestore object, this makes no sense:
const docRef = doc(db, `${user?.uid}/orders/`);
const docSnap = await getDoc(docRef);
You're creating a reference to a document named orders in a collection user?.uid. This does not match your data structure, which would be:
const ordersRef = collection(db, `users/${user?.uid}/orders`);
So now ordersRef is a collection to the orders subcollection for the specific user. You can then read if by calling getDocs:
const ordersQuerySnapshot = await getDocs(ordersRef);
And loop through them with:
ordersQuerySnapshot.docs.forEach((doc) => {
console.log(doc.id, doc.data());
})
