to create CRUD with firestore. we need to use admin and access via service account. go to service accounts and generate a new "private key"

put this in index.js

const serviceAccount = require('./permissions.json') admin.initializeApp({ credential: admin.credential.cert(serviceAccount), databaseURL: "https://restapi-js.firebaseio.com" })
