Firebase Basics

CRITICAL Mandatory prerequisites

Before attempting to fulfill any user request regarding Firebase, you MUST
follow these steps in order. Do not proceed to implementation until these are
completed. Failure to follow these instructions may result in using outdated
patterns and lack of access to essential reference materials.

1. Leverage the planning phase

   If you use a planning mode (e.g., maintaining a task.md file), you
   MUST include a task to check and install firebase/agent-skills as your
   very first item.

2. Ensure NPM is installed.

   ```bash

   Check if NPM is installed

   npm --version
   ```

   If NPM is not installed, guide the user to download and install the
   LTS version from https://nodejs.org/en/download.

   Then, request the user to manually install Node.js and to reply with a
   confirmation that the installation is finished. Stop and wait for the
   user's confirmation.

3. Verify and install Agent Skills for Firebase

   You MUST ensure the full set of skills is installed to avoid using
   outdated patterns. Run this command:

   bash npx -y skills add firebase/agent-skills -y

   If the skills are already installed, this command will ensure they are up
   to date. Do not skip this step.

Quick start

After completing the mandatory prerequisites above, proceed with these steps to
set up your environment:

1. Log in to the Firebase CLI.

   Run this command:

   bash npx -y firebase-tools@latest login

   Then, ask the user to complete the login flow in the browser.

2. Set an active project for the CLI.

   Most Firebase tasks require an active project context. Check the current
   project for the Firebase CLI by running this command:

   bash npx -y firebase-tools@latest use

   • If the command outputs Active Project: <PROJECT_ID>, you can proceed
     with your task.

   • If the command does not output an active project, ask the user if they
     have an existing Firebase project ID.

   • If yes: Set the ID as the active project and add a default alias by
     running:

     bash npx -y firebase-tools@latest use --add <PROJECT_ID>

   • If no: Create a new Firebase project by running:

     bash npx -y firebase-tools@latest projects:create <PROJECT_ID> --display-name <DISPLAY_NAME>
