firebase.auth is not a function

Question

I am using Webpack with firebase and firebase-admin.

To install firebase I ran:

npm install --save firebase 

I am importing firebase using:

import * as firebase from 'firebase/app' import 'firebase/auth' 

I also tried:

import * as firebase from 'firebase' 

And I tried:

const firebase = require('firebase') 

As suggested in web get started guide.

However, when I try to use firebase.auth() I get an error:

console.js:32 TypeError: firebase.auth is not a function

When I use the debugger to inspect firebase I see that it in fact does not have an auth function:

> firebase  {__esModule: true, initializeApp: ƒ, app: ƒ, Promise: ƒ, …} 

How can I get auth() included as a function using webpack?

Answer 1

I fixed this by deleting my node_modules directory and reinstalling everything.

Also I'm importing firebase like so:

import firebase from 'firebase' require('firebase/auth')
