Example using Flamelink with Cloud Firestore in a Firebase Cloud Function

flamelink-cloud-functions-cloud-firestore.js

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const flamelink = require('flamelink/app');
// Only import the modules that you need (change `cf` to `rtdb` for Realtime DB)
require('flamelink/cf/settings');
require('flamelink/cf/content');
require('flamelink/cf/storage');
require('flamelink/cf/navigation');
require('flamelink/cf/users');

const firebaseApp = admin.initializeApp(functions.config().firebase);

const app = flamelink({
  firebaseApp, 
  dbType: 'cf' // can be `rtdb` for Realtime DB
});

exports.addMessage = functions.https.onRequest((req, res) => {
  return app.content.get({ schemaKey: 'messages' })
    .then(messages => {
      return res.status(200).json({ messages });
    })
    .catch(error => {
      // In a production system you probably don't want to send the full `error` object back
      res.status(500).json({ error });
    });
});
