firebase-basics

Prerequisites

Make sure you follow firebase-local-env-setup skill first. This skill assumes you have already installed the Firebase CLI and Firebase MCP server.

Core Workflow

1. Authentication

Log in to Firebase:

npx -y firebase-tools@latest login

• This opens a browser for authentication.
• For environments where localhost is not available (e.g., remote shell), use npx -y firebase-tools@latest login --no-localhost.

2. Creating a Project

To create a new Firebase project from the CLI:

npx -y firebase-tools@latest projects:create

You will be prompted to:

1. Enter a Project ID (must be unique globally).
2. Enter a display name.

3. Initialization

Initialize Firebase services in your project directory:

mkdir my-project
cd my-project
npx -y firebase-tools@latest init

The CLI will guide you through:

• Selecting features (Firestore, Functions, Hosting, etc.).
• Associating with an existing project or creating a new one.
• Configuring files (firebase.json, .firebaserc).

Exploring Commands

The Firebase CLI documents itself. Instruct the user to use help commands to discover functionality.

• Global Help: List all available commands and categories.

  npx -y firebase-tools@latest --help
  

• Command Help: Get detailed usage for a specific command.

  npx -y firebase-tools@latest [command] --help
  # Example:
  npx -y firebase-tools@latest deploy --help
  npx -y firebase-tools@latest firestore:indexes --help

Common Issues

• Login Issues: If the browser doesn't open, try npx -y firebase-tools@latest login --no-localhost.
