firebase.firestore() is not a function when trying to initialize Cloud Firestore

When I try to initialize Firebase Cloud Firestore, I ran into the following error:

Uncaught TypeError: WEBPACK_IMPORTED_MODULE_0_firebase.firestore is not a function

I installed firebase with npm install firebase --save previously.

import * as firebase from 'firebase';
import router from '../router';

const config = {
        apiKey: "a",
        authDomain: "a",
        databaseURL: "a",
        projectId: "a",
        storageBucket: "a",
        messagingSenderId: "a"
};
if(!firebase.apps.length){
  firebase.initializeApp(config);
  let firestore = firebase.firestore();
}

I fixed it by importing multiple libraries: firebase and firebase/firestore. That's because the firebase core library does not include the firestore library.

import firebase from 'firebase/app';
import 'firebase/firestore';

First, make sure you have latest version of firebase:

npm install firebase@4.12.0 --save

Next, add both firebase and firestore:

const firebase = require("firebase");
// Required for side-effects
require("firebase/firestore");

Initialize the firebase app:

firebase.initializeApp({
  apiKey: '### FIREBASE API KEY ###',
  authDomain: '### FIREBASE AUTH DOMAIN ###',
  projectId: '### CLOUD FIRESTORE PROJECT ID ###'
});

// Initialize Cloud Firestore through Firebase
var db = firebase.firestore();

import { firebase } from '@firebase/app';
import '@firebase/firestore'

If you're using authentication as well

import '@firebase/auth';
