import * as firebase from "firebase/app"; import 'firebase/firestore' const firebaseConfig = { apiKey: "api key", authDomain: "asdjfg.firebaseapp.com", databaseURL: "aksdjgh.firebaseio.com", projectId: "test-asdkjkgfsg", storageBucket: "tasdgaest-asdfg-asgafg.appspot.com", messagingSenderId: "asgas5554", appId: "1:asgasdgasgef76b" }; const app = firebase.initializeApp(firebaseConfig); const db = app.firestore(); export default db

¿Por qué dice que app.firestore no es una función?

He instalado firebase y firebase-tools
