Synchronously Retrieving Product Details and Images from Firebase in React Application

Problem Description

I’m developing an e-commerce React application and have successfully uploaded product information and images to Firebase. However, I’m experiencing challenges retrieving and displaying both product content and associated images concurrently.

Current Implementation

const [products, setProducts] = useState([]);

const fetchProductCatalog = async () => {
    const productCollection = collection(db, "inventory");
    const productQuery = query(productCollection, orderBy("productId"));
    
    await getDocs(productQuery)
        .then((snapshot) => {
            const productData = snapshot.docs.map((doc) => ({
                ...doc.data(),
                productId: doc.data().productId,
                title: doc.data().title,
                summary: doc.data().summary
            }));
            setProducts(productData);
        })
        .catch((error) => {
            console.error("Product retrieval failed", error);
        });
};

Any suggestions on improving data retrieval efficiency would be greatly appreciated!

hey, try using promise.all() for syncin ur product and img data. works gr8 with firebase! u can parallelize ur reqsts and reduce loading time. jst make sure u handle errors proprely :slight_smile:

Comprehensive approach here! When handling Firebase data retrieval, I recommend implementing a more robust async strategy. You could leverage Promise.all() for parallel data fetching, which allows simultaneous product and image loading. Consider creating a separate function to retrieve image references and URLs alongside product details.

A refined implementation might involve creating a method that uses Promise.all() to concurrently fetch product metadata and corresponding image download URLs. This approach minimizes sequential loading and reduces overall retrieval time. Just ensure proper error handling and consider implementing loading states to enhance user experience during data synchronization.
