Firestore obtient le premier document dans la collection et supprimez-le
// you need a reference field like timestamp
// this will work in a cloud function
return admin.firestore().collection("yourCollection")
.orderBy("yourTimestamp", "desc")
.limit(1)
.get()
.then(querySnapshot => {
if (!querySnapshot.empty) {
//We know there is one doc in the querySnapshot
const queryDocumentSnapshot = querySnapshot.docs[0];
return queryDocumentSnapshot.ref.delete();
} else {
console.log("No document corresponding to the query!");
return null;
