Prerequisites

Node.js and npm

To use the Firebase CLI, you need Node.js (version 20+ required) and npm (which comes with Node.js).

Recommended: Use a Node Version Manager This avoids permission issues when installing global packages.

Install a Node Version Manager:
- Mac/Linux: Follow the installation instructions on the official nvm repository.
- Windows: Download nvm-windows
Install Node.js:
```
nvm install 24
nvm use 24
```

Alternative: Official Installer Download and install the LTS version from nodejs.org.

Verify Installation:

node --version
npm --version
npx -y firebase-tools@latest --version

Core Workflow

1. Authentication

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:

Enter a Project ID (must be unique globally).
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
