A collection of sample apps demonstrating common use cases for Cloud Functions for Firebase.
Cloud Functions for Firebase Sample Library is a curated collection of example applications that demonstrate how to implement various serverless workflows using Cloud Functions for Firebase. It solves the problem of learning how to connect Firebase services (like Firestore, Auth, and Storage) with event-driven cloud functions by providing concrete, runnable code for common scenarios.
Developers building applications with Firebase who need practical examples of serverless function implementations, especially those working with Node.js or Python and looking to automate backend tasks triggered by Firebase events.
Developers choose this library because it offers officially maintained, well-documented samples that cover a wide range of real-world use cases, reducing the learning curve and providing reliable reference code for production Firebase projects.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Covers all major Firebase triggers including Firestore, Auth, Storage, HTTPS, and Pub/Sub, with dedicated quickstart samples for each, as listed in the README.
Provides samples in Node.js (both 1st and 2nd gen) and Python (2nd gen), allowing developers to choose based on their stack, as highlighted in the cross-language support.
Includes practical use cases like image processing, payments with Stripe, and third-party integrations, demonstrated in samples such as thumbnail generation and GitHub-to-Slack.
Offers unit testing setups with Jest and Mocha, plus development boilerplates for server-side rendering, helping ensure code reliability and faster setup.
Python support is in public preview with potential backward-incompatible changes and limited support, as warned in the README, making it risky for production use.
Some features, like Auth user create/delete triggers, aren't yet supported in 2nd gen functions, creating gaps for teams adopting newer Firebase versions.
All samples require the Blaze pay-as-you-go billing plan to deploy, which may deter hobbyists or those on strict budgets, as noted in the prerequisites.
