Cannot find namespace 'FirebaseFirestore' - Node.js, Express, Typescript

Question

I'm using the Firebase Admin SDK in my Express + Typescript server. I'm trying to use Firestore's method withConverter() However, I get the error "Cannot find namespace 'FirebaseFirestore'.ts(2503)". How can I deal with this?

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount)
});

const firestore = admin.firestore();

interface BlogpostColletion {
    text: String,
    title: String,
}

interface UsersCollection {
    blogposts: BlogpostColletion
}

const converter = {
    toFirestore: (data: UsersCollection) => data,
    // PROBLEM HERE "Cannot find namespace 'FirebaseFirestore'.ts(2503)" 
    fromFirestore: (snap: FirebaseFirestore.QueryDocumentSnapshot) =>
        snap.data() as UsersCollection
}

Have you tried `admin.firestore.QueryDocumentSnapshot` instead of `FirebaseFirestore.QueryDocumentSnapshot`? — Dharmaraj, Sep 25 '21 at 15:58
Thank you. Changing to "admin.firestore.QueryDocumentSnapshot" gave the issue "cannot find namespace admin". But changing the import of admin from "var admin = require("firebase-admin")" to "import * as admin from 'firebase-admin'" seems to have solved it :) — A.G, Sep 28 '21 at 07:02

You can import QueryDocumentSnapshot from Admin SDK like this:

import * as admin from "firebase-admin"

fromFirestore: (snap: admin.firestore.QueryDocumentSnapshot)
