VisualizaçõesCheck if value exist firebase
I'm trying to check if there is a cart with a userID but it doesn't seem to be working
Here is my code attempt, I don't know where I'm going wrong, I have firebase initialized
let storage = Cart.shared.firebase
storage.child("cart").orderByChild("userId").equalTo("Eyo1DCNZU8TfB16zJDuULpKAx2V2").once("value",snapshot => {
if (snapshot.exists()){
const userData = snapshot.val();
console.log("exists!", userData);
}else{
console.log("nope")
}
});

You are using Firestore but writing code for Realtime database. Try the code below:
firebase.firestore().collection("cart").where("userId", "==", USER_ID).get().then((qSnap) => {
if (qSnap.empty) {
console.log("No cart found for user")
} else {
console.log("User carts")
qSnap.docs.forEach((d) => {
console.log(d.data())
})
}
})
