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 (nvm) This avoids permission issues when installing global packages.

Install nvm:

Mac/Linux:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash

Windows: Download nvm-windows

Install Node.js:
bash
```
nvm install 24
nvm use 24
```

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

Verify Installation:

bash

node --version
npm --version

Core Workflow

1. Installation

Install the Firebase CLI globally via npm:

bash

npm install -g firebase-tools

Verify installation:

bash

firebase --version

2. Authentication

Log in to Firebase:

bash

firebase login

This opens a browser for authentication.
For environments where localhost is not available (e.g., remote shell), use
```
firebase login --no-localhost
```
.

3. Creating a Project

To create a new Firebase project from the CLI:

bash

firebase projects:create

You will be prompted to:

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

4. Initialization

Initialize Firebase services in your project directory:

bash

mkdir my-project
cd my-project
firebase 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.
bash
```
firebase --help
```

Command Help: Get detailed usage for a specific command.

bash

firebase [command] --help
# Example:
firebase deploy --help
firebase firestore:indexes --help

SDK Setup

Detailed guides for adding Firebase to your app:

Web: See references/web_setup.md

Common Issues

Permission Denied (EACCES): If
```
npm install -g
```
fails, suggest using a node version manager (nvm) or
```
sudo
```
(caution advised).
Login Issues: If the browser doesn't open, try
```
firebase login --no-localhost
```
.
