Say Hello to Cloud Functions for Firebase 2nd Gen

Get to know Cloud Functions for Firebase (2nd gen), the next generation of Functions-as-a-Service that built on Cloud Run and Eventarc to gives you more powerful infrastructure, advanced control over performance and scalability.

Transcript

1. @Jirawatee Google Developer Expert in Firebase Say Hello to Cloud Functions for Firebase 2nd Gen
2. “Write and Run backend code in response to events triggered by Firebase features and HTTPS requests” Cloud Functions for Firebase
4. Realtime Database Trigger
5. Events exports.make Uppercase = functions.da tabase()... exports.mode rate = functions.da tabase()... exports.send Email = functions.da tabase()... Authentication Firestore Realtime Database Storage Extensions App Distribution Crashlytics Performance Monitoring Test Lab Remote Config Analytics Firebase Triggers
7. HTTP Request
8. Cloud Scheduler const { onSchedule } = require("firebase-functions/v2/scheduler"); exports.cronjob = onSchedule("every day 10:00", async (event) => { // Send notification }); Schedule Functions
9. 2nd Generation GA
10. Cloud Build Cloud Run Eventarc Cloud Functions 2nd Generation
11. 1st Gen: One request per instance 2nd Gen: Many requests per instance Concurrency
12. 150ms 150ms 150ms 150ms 150ms 150ms 200ms 200ms 200ms 300ms 60ms 60ms 60ms 60ms
13. Granular control and optimize performance 32GB New Instance Size
14. • Up to 60 mins for HTTP triggered functions • Up to 9 mins for event triggered functions Request Timeout
15. Language Support Public Preview
16. Firebase Alert Events Crashlytics Performance Monitoring App Distribution New Events
17. Firebase Crashlytics const { onNewFatalIssuePublished } = require("firebase-functions/v2/alerts/crashlytics"); exports.sendSmsAlert = onNewFatalIssuePublished((event) => { // Send SMS }); New Events
18. Events Custom Event
19. Custom Event Events
20. 20 + Firebase Authentication Cloud Identity New Events
21. import {beforeUserCreated} from "firebase-functions/v2/identity"; export const blockauth = beforeUserCreated((event) => { }); const user = event.data; // Ensure only google.com emails can log into the changelog app if (!user?.email?.includes('@google.com')) { throw new HttpsError( "permission-denied", "Only @google.com are allowed to register."); } Blocking Functions
22. Task Queue Functions Cloud Tasks
23. Upgrade your code to 2nd Gen Coding Style
24. Both APIs are in the same SDK const functions = require("firebase-functions/v1"); const { onRequest } = require("firebase-functions/v2/https"); exports.f1 = functions.https.onRequest((req, res) => { res.send("Hello from Firebase!"); }); exports.f2 = onRequest((req, res) => { res.send("Hello from Firebase!"); });
25. Runtime options const functions = require("firebase-functions/v1"); const { onRequest } = require("firebase-functions/v2/https"); const cors = require("cors")({ origin: true }); exports.f1 = functions.runWith({ memory: "1GB" }).https.onRequest((req, res) => { cors(req, res, () => { res.send("Hello from Firebase!"); }); }); exports.f2 = onRequest({ memory: "1GB", cors: true }, (req, res) => { res.send("Hello from Firebase!"); });
26. Runtime options const { onRequest } = require("firebase-functions/v2/https"); const { setGlobalOptions } = require("firebase-functions/v2"); setGlobalOptions({ region: "asia-southeast1", memory: "1GB", concurrency: 40 }); export const api = onRequest(apiHandler); export const content = onRequest(contentHandler);
27. Loading environment variables specified in a .env file to your application runtime Securely store API keys, passwords, certificates, and other sensitive data. Environment Variables Cloud Secret Manager Strongly-typed environment configuration with parameters that are validated at deploy time Parameterized Config Environment Configuration New
28. Parameterized Configuration const { onRequest } = require("firebase-functions/v2/https"); const { defineString, defineInt, defineSecret } = require("firebase-functions/params"); const welcomeMessage = defineString("WELCOME_MESSAGE"); const concurrencyConfig = defineInt("CONCURRENCY", { default: 80 }); const apiKey = defineSecret("API_KEY"); exports.f2 = onRequest({secrets: [apiKey], concurrency: concurrencyConfig}, (req, res) => { const sampleApiKey = apiKey.value(); res.send(`${welcomeMessage.value()}! I am a function.`); });
29. Emulator Suite Auth Firestore RTDB Storage Hosting Extensions
30. Demo
31. Enhancements in Cloud Functions 2nd Gen ⚡Concurrency (Up to 1000 concurrent requests per instance) ☁ Larger in memory, and compute intensive (Up to 32GiB RAM with 8 vCPUs) 󰞵 Python support 🚨 New events (Firebase Alerts, Auth Blocking, and Firebase Extensions) 🌐 Secure your callable and HTTP functions with a new CORS ✔ Task Queue functions ⏳ Long-running in HTTP Functions (Up to 1 hour timeout) 🖥 Modern JavaScript (config functions globally, options objects, and modular imports) Recap
