Firebase Utilities

Simple utilities to reduce some firebase-admin tasks.

Overview

getFirebaseAdmin(credential, realtimeDbUrl)

Easy function to initialize firebase-admin only once.

validateToken(token, firebaseAdminInstance)

Validates an idToken generated by Firebase Auth (not access token, idToken).

Also supports the format Bearer <token> or just <token>

getTestIdToken(firebaseAdminInstance, userId, claims)

Gets an Id Token from the Firebase Emulator.

Usage

An example of using all three tools

import { getFirebaseAdmin, validateToken, getTestIdToken } from '@anatine/firebase-utils'

const admin = getFirebaseAdmin();
const uid = 'SomeUserId'

const { idToken } = await getTestIdToken({admin, uid, claims: {status: 'this is awesome'}})

const decodedUserData = await validateToken(idToken, admin)

console.log(decodedUserData)
