## What it is
Cloud Functions for Firebase is a serverless framework that runs JavaScript, TypeScript, Python, and (experimentally) Dart backend code in response to events like HTTPS requests, Firestore/Realtime Database changes, Auth triggers, and scheduled jobs. The associated repositories provide the functions SDK and a large library of quickstart and sample apps demonstrating each trigger type.

## Use cases
- run backend code in response to firestore events
- create https api endpoints without managing servers
- trigger functions on firebase auth user signup
- process cloud storage file uploads automatically
- schedule recurring jobs with cloud scheduler
- build callable functions for flutter apps in dart
- stream responses from callable functions to clients

## When to choose
- you already use Firebase and want event-driven backend logic integrated with its services
- you want zero-maintenance autoscaling functions on Google Cloud infrastructure
- you want official samples and quickstarts for every trigger type in Node, Python, or Dart

## When to avoid
- you need long-running or compute-heavy workloads unsuited to function timeouts
- you want to avoid the Blaze pay-as-you-go billing plan required for deployment
- you need a self-hosted or cloud-provider-agnostic serverless solution
