I am querying firestore for some results. But before running forEach loop on docs, i want to know if there are any docs in collection snapshot, and snapshot.exist() always giving false even if there are docs in it.
db.collection("users").where("mobile_no", '==', mobileToCheck).get().then(function(querySnapshot){
if (querySnapshot.exists) { \\THIS ALWAYS RETURNING FALSE
querySnapshot.forEach(doc => {
console.log(doc.data());
});
console.log(mobileToCheck + "Exist In DB");
}else{
console.log(mobileToCheck + "Do Not Exist In DB");
}
});
How would i know if there are any results?

Reset to default 9The QuerySnapshot object doesn't have an exists property, that one is only available on DocumentSnapshots.
You can either check querySnapshot.empty or querySnapshot.size
