Scaling Firebase Remote Config Using Kotlin, Cloud Functions, and the Firebase Admin SDK

on YouTube ↗53m

" summary

Builds a Cloud Function in Kotlin that listens to google.firebase.com pubsub events, fetches specific Remote Config templates via the Firebase Admin SDK, and posts Slack alerts. Adds formatted diffs using java-diff-utils so the message shows exactly which parameters and conditions were added removed or updated. Implements validation hooks that trigger an automatic rollback to version minus one when values fail type or range checks. Provides a local CLI (built with Clikt) to promote parameters from dev to prod and publishes the updated template when confirmations pass.
