Firebase Remote Config Basics

This handles Firebase Remote Config setup and template management through both SDK integration and CLI commands. You'll want this when you need to set up feature flags or change app behavior without pushing updates. It covers Android and iOS SDK setup, walks through the fetch-and-activate pattern, and importantly includes the full CLI workflow for getting, editing, and deploying your config JSON with proper verification steps. The troubleshooting section is practical, covering npx registry errors and project context issues. One thing to note: it correctly emphasizes the load-for-next-startup pattern over blocking fetches, which saves you from common performance mistakes.

Remote Config

This skill provides a complete guide for getting started with Remote Config on Android or iOS. Remote Config allows you to change the behavior and appearance of your app without publishing an app update by maintaining a cloud-based configuration template.

Prerequisites

Provisioning Remote Config requires both a Firebase project and a Firebase app, either Android or iOS. To manage the Remote Config template and conditions via the command line, use the Firebase CLI. See the firebase-basics skill for references on project initialization.

Troubleshooting Execution

Handling npx 403 Forbidden Errors

If npx -y firebase-tools@latest fails due to registry permissions (403 error):

Inform the user: "I am unable to fetch the latest Firebase tools via npx due to a registry error."
Fallback: Attempt to use the local firebase command directly if the user confirms it is installed globally (npm install -g firebase-tools).
