# OneDrive ↔ Google Drive Streamer

A secure, high-performance application to stream files bidirectionally between Microsoft OneDrive and Google Drive. 
Now powered by a **Node.js Express backend** for reliable server-side streaming and token management.

## Features

- � **Bidirectional Transfers**: Move files from OneDrive to Google Drive AND Google Drive to OneDrive.
- 🚀 **Server-Side Streaming**: Files are piped directly between cloud providers on the server, ensuring faster and more reliable transfers for large files.
- � **Secure OAuth 2.0**: Implements robust Authorization Code Flow via the backend.
- 📊 **Real-time Progress**: Track transfer status with live progress updates.
- 📁 **File Management**: Browse and select files from your connected cloud storage.

## Prerequisites

- Node.js (v18 or higher)
- npm or yarn

## Setup

### 1. Clone the repository
```bash
git clone <repository-url>
cd <repository-directory>
```

### 2. Install Dependencies
You need to install dependencies for both the frontend and the backend.

**Frontend:**
```bash
npm install
```

**Backend:**
```bash
cd server
npm install
cd ..
```

### 3. Configure OAuth Applications

#### Step A: Microsoft Azure (OneDrive)

1. Go to **[Azure Portal](https://portal.azure.com)** → **Azure Active Directory** → **App registrations**
2. Click **"New registration"**
3. Fill in:
   - **Name**: `CloudStream Transfer` (or any name)
   - **Supported account types**: "Accounts in any organizational directory and personal Microsoft accounts"
   - **Redirect URI**: Select "Single-page application (SPA)" and enter:
     - Development: `http://localhost:5173/auth/callback`
     - Production: `https://yourdomain.com/auth/callback`
4. Click **Register**
5. Copy the **Application (client) ID** → This is your `VITE_MS_CLIENT_ID`
6. Go to **Certificates & secrets** → **New client secret**
   - Add a description and expiry
   - Copy the **Value** immediately (shown only once) → This is your `MS_CLIENT_SECRET`
7. Go to **API permissions** → **Add a permission** → **Microsoft Graph** → **Delegated permissions**
   - Add: `Files.Read`, `Files.Read.All`, `Files.ReadWrite`, `Files.ReadWrite.All`, `User.Read`
   - Click **Grant admin consent** (if you're an admin)

#### Step B: Google Cloud (Google Drive)

1. Go to **[Google Cloud Console](https://console.cloud.google.com)**
2. Create a new project or select existing one
3. Go to **APIs & Services** → **Enabled APIs & Services**
   - Click **+ ENABLE APIS AND SERVICES**
   - Search for **"Google Drive API"** and **Enable** it
4. Go to **APIs & Services** → **Credentials**
5. Click **+ CREATE CREDENTIALS** → **OAuth client ID**
   - If prompted, configure the **OAuth consent screen** first:
     - User Type: External
     - App name, support email, developer email (required fields)
     - Scopes: Add `https://www.googleapis.com/auth/drive`
6. Back to Credentials → **OAuth client ID**:
   - Application type: **Web application**
   - Name: `CloudStream Transfer`
   - Authorized redirect URIs:
     - `http://localhost:5173/auth/callback` (development)
     - `https://yourdomain.com/auth/callback` (production)
7. Click **Create**
8. Copy **Client ID** → This is your `VITE_GOOGLE_CLIENT_ID`
9. Copy **Client Secret** → This is your `GOOGLE_CLIENT_SECRET`

#### Step C: Create Environment Files

**Frontend (`.env` in root directory):**
```env
VITE_MS_CLIENT_ID=your_microsoft_client_id
VITE_GOOGLE_CLIENT_ID=your_google_client_id
```

**Backend (`server/.env`):**
```env
PORT=9173

# Microsoft (same Client ID as frontend + secret)
VITE_MS_CLIENT_ID=your_microsoft_client_id
MS_CLIENT_SECRET=your_microsoft_client_secret

# Google (same Client ID as frontend + secret)
VITE_GOOGLE_CLIENT_ID=your_google_client_id
GOOGLE_CLIENT_SECRET=your_google_client_secret

# Must match your OAuth app redirect URI
REDIRECT_URI=http://localhost:5173/auth/callback
```

> **🔐 Security Note**: Client IDs are public (like your app's name). Client Secrets are private and ONLY stored on the backend - never exposed to browsers. Your files are safe!

### 4. Run the Application

You need to run both the backend server and the frontend client.

**Start Backend (Terminal 1):**
```bash
cd server
npm run dev
```
*Server runs on http://localhost:3001*

**Start Frontend (Terminal 2):**
```bash
npm run dev
```
*Frontend runs on http://localhost:5173*

## Project Structure

## Docker & Coolify Deployment

### Local Docker
```bash
# Build and run with Docker Compose
docker-compose up --build

# Access at http://localhost
```

### Coolify Deployment

#### From Public Repository
1. In Coolify, go to **Projects → New → From Git Repository**
2. Select **GitHub/GitLab/Bitbucket** and enter the repo URL
3. Set **Build Pack** to `Docker Compose`
4. Configure environment variables in Coolify's UI

#### From Private Repository  
1. In Coolify, go to **Settings → Private Keys** and add your SSH key
2. Create new project with **Private Repository** option
3. Use SSH URL: `git@github.com:username/repo.git`
4. Configure environment variables in Coolify's UI

#### Required Environment Variables (Coolify UI)
| Variable | Description |
|----------|-------------|
| `VITE_MS_CLIENT_ID` | Microsoft/Azure OAuth Client ID |
| `MS_CLIENT_SECRET` | Microsoft/Azure OAuth Secret |
| `VITE_GOOGLE_CLIENT_ID` | Google OAuth Client ID |
| `GOOGLE_CLIENT_SECRET` | Google OAuth Secret |
| `REDIRECT_URI` | `https://yourdomain.com/auth/callback` |

> **Important**: Update your OAuth app redirect URIs in Azure Portal and Google Cloud Console to match your Coolify domain.
