Enable Firebase Feature

after we add our app in firebase and put the google-service.json file into our project, we need to enable some firebase features that our app uses, first is the authentication feature, so that our app can register a new account and also login

1. Enable Firebase Authentication

• in Firebase Dashboard, click Authentication -> Sign in Method -> Email/Password

• and then enable email, and click save

2. Enable Firebase Firestore

we also need to enable Firebase Firestore, so we can save our app data in firebase

• click Firestore Database -> Create Database

• and chose Start in Production Mode -> and then click Next

• and then chose datacenter near you, and click Enable

3. Enable Firebase Functions

we also need to enable Firebase Firestore, but to activate the firebase function, we are required to upgrade our project to the Blaze Plan

• Click Function and click Upgrade Project

• Click Continue

• and here you are required to enter payment information, but don't worry you will not be charged a fee, as long as your resource usage is still within the limits set by firebase here https://firebase.google.com/pricing

• After your blaze plan is active, your firebase function should also be active

• okay, for now that's the only feature that must be activated in this Firebase panel, the rest will be activated when we deploy the Firebase Cloud
