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

Answer 1

This is because firebase-auth script is not added.

First you have to install npm files in your node modules by

npm install firebase --save
npm install firebase-admin --save

Then you have to add the script of firebase.auth after firebase-app script and make sure the version is same.

Before fix:

AFTER FIX YOU NEED TO ADD BOTH THE SCRIPT AND AFTER THIS ADD YOUR FIREBASE ACCOUNT SCRIPT AS FOLLOWS

THEN IT SHOULD WORK FINE
