Functions Commands

Deploy event-driven serverless functions with Cloud Functions. Manage triggers, environment variables, and function configurations.

Pro Tips

Use 2nd gen functions for longer timeouts (up to 60 min) and more memory.

Test locally with 'functions-framework' before deploying.

Use Secret Manager for sensitive configuration instead of env vars.

Common Mistakes

1st gen functions have 9-minute timeout; 2nd gen supports up to 60 minutes.

Cold starts can add seconds of latency - keep functions warm if needed.
