将firebase v8升级到v9

Question

Firebase ->Firestore

我有这段代码，我想把它转换成v9，但似乎不能找出正确的语法。

db.collection('chats').doc(router.query.id).collection('messages').orderBy('timestamp', 'asc')

Answer 1

就像这样:

const ref = collection(db, `chats/${router.query.id}/messages`)
const q = query(ref, order('timestamp', 'asc'))
const snapshot = await getDocs(q)
if(snapshot.exits()) console.log(snapshot.docs)
