VisualizaçõesSetting up a counter in a document and then retrieve it using Firestore: Would this be alright or would this be too expensive?
Under the orders collection, I created a document called counts which would store the counts for the status of the orders:
I then created a function to increment the status with "delivered"
And then to display this:
useEffect(async () => {
const docRef = doc(db, "orders", "counts");
const docSnap = await getDoc(docRef);
if (docSnap.exists()) {
console.log("Document data:", docSnap.data());
} else {
// doc.data() will be undefined in this case
console.log("No such document!");
}
}, []);

Yes, this is one way to do it I suppose, 'expensive', that's up to you and how many calls you might end up with, as I know Firestore has a limited amount of free document calls.
Another thing is you should not, and I repeat should not make a useEffect asynchronous, the best and right way to perform asynchronous code inside a useEffect would be to declare it inside and then run it like below
useEffect(() => {
const AsyncExample = async () => {
// async code in here
}
AsyncExample()
}, [])
