Getting Started

Prerequisites

• Node.js (v18+)
• npm or yarn
• Firebase CLI (npm install -g firebase-tools)

Environment Setup

1. Clone the repository:

git clone <repository-url>
cd worldcup-2026-pool

2. Install dependencies:

# Install root dependencies
npm install

# Install web dependencies
cd web && npm install

# Install functions dependencies
cd ../functions && npm install

3. Set up environment variables for the web app:

cd web
cp .env.example .env

4. Fill in your Firebase configuration values in web/.env:

VITE_FIREBASE_API_KEY=your_api_key
VITE_FIREBASE_AUTH_DOMAIN=your_project.firebaseapp.com
VITE_FIREBASE_DATABASE_URL=https://your_project.firebaseio.com
VITE_FIREBASE_PROJECT_ID=your_project_id
VITE_FIREBASE_STORAGE_BUCKET=your_project.firebasestorage.app
VITE_FIREBASE_MESSAGING_SENDER_ID=your_messaging_sender_id
VITE_FIREBASE_APP_ID=your_app_id
VITE_FIREBASE_MEASUREMENT_ID=your_measurement_id

You can find these values in your Firebase Console under Project Settings > General > Your apps.

5. Update Firebase project configuration (if forking):

Update .firebaserc with your project ID:

{
  "projects": {
    "default": "your-project-id"
  }
}

Update the site in firebase.json (must match your Firebase Hosting site name):

{
  "hosting": {
    "site": "your-project-id",
    ...
  }
}

Alternatively, you can skip editing these files and use the CLI:

firebase use your-project-id
firebase deploy --project your-project-id
