This repository provides an example about handling counters in Firestore using Cloud Functions for Firebase.

Check the article for more information.

Running the project

1. Install dependencies

This project is using pnpm as the package manager.

pnpm install

2. Run functions locally

pnpm start

The start script is configured to run the Firebase Emulator, importing data from the /emulator folder and exporting data to the same folder on exit. When you run pnpm start, this script will be executed:

firebase emulators:start --import=./emulator --export-on-exit ./emulator

3. Play with the Emulator UI to see the functions in action

After successfully executing pnpm start, open the Firestore Emulator UI at http://localhost:4000/firestore then add and/or delete documents from the residents collection to see the functions in action.
