What you can build with Cloud Functions

on YouTube ↗36m

" summary

Cloud Functions for Firebase runs Node.js serverless code that auto-scales and charges per invocation, with HTTP, Storage, Firestore, Realtime DB, Auth, Pub/Sub and Hosting triggers. Examples: an HTTP uppercase API built in four lines with local testing via firebase serve and an emoji-replace function that rewrites Firestore fields; image-resize thumbnails and FCM push via admin.messaging sendToTopic (room ID as topic). Deploy yields a public URL, functions return promises, runtime is Node LTS, no built-in scheduler and free tier limits outbound sockets without billing.
