I'm building a web application where users can make appointments with doctors and I want to prevent users from making appointments with the same doctor at the same time and date that other users have already requested. I'm using a firestore database to store appointment information as a document. Here is my function that handles the check and pushes it to my firebase database:
const addAppointment = async (date: Date | null, speciality: string | undefined) => { const appointmentsRef = collection(db, "appointments"); const q = query(appointmentsRef, where("speciality", "==", speciality), where("date", "==", date)) const docs = await getDocs(q); docs.forEach((doc: any) => { console.log(doc.data()) }) console.log(docs.docs.length) if (docs.docs.length === 0) { try{ await addDoc(collection(db, "appointments"), { email: auth.currentUser?.email, date, speciality });} catch (err) { console.error(err); } return false } return true };
On page refresh, if I try to book an appointment that has already been requested, the docs length is 0 and I can make the same appointment. However, if I try again (without refreshing), the doc length is 1 and it is not pushed to the database.

I am now parsing the date field as a string and actually comparing strings instead of dates.
