## Integration Patterns

### Direct WebSocket Connection

Most ecosystem components connect directly to the ErikrafT Drop WebSocket server:

```javascript theme={null}
// Example connection pattern
const ws = new WebSocket('wss://drop.erikraft.com/server');
ws.onopen = () => {
    ws.send(JSON.stringify({
        type: 'join-ip-room',
        client_type: 'android' // or 'discord-bot', 'vs-code-extension', etc.
    }));
};
```

### Client Type Identification

Each ecosystem component uses a unique client type:

| Component         | Client Type         | Purpose                    |
| ----------------- | ------------------- | -------------------------- |
| Web App           | `browser`           | Standard browser client    |
| Android App       | `android`           | Native Android application |
| VS Code Extension | `vs-code-extension` | VS Code integration        |
| Discord Bot       | `discord-bot`       | Discord server integration |
| Browser Extension | `browser`           | Browser integration        |

### Feature Mapping

Different components support different feature sets:

| Feature             | Web App | Android | iOS | Extensions | Discord         |
| ------------------- | ------- | ------- | --- | ---------- | --------------- |
| WebRTC P2P          | ✅       | ✅       | ✅   | ✅          | ❌\*             |
| WebSocket Fallback  | ✅       | ✅       | ✅   | ✅          | ✅               |
| QR Code Scanning    | ✅       | ✅       | ✅   | ✅          | ❌               |
| System Integration  | ❌       | ✅       | ✅   | ✅          | ❌               |
| Auto-Accept         | ✅       | ✅       | ✅   | ✅          | ✅               |
| Multi-file Transfer | ✅       | ✅       | ✅   | ✅          | ✅ (3 files max) |

\*Discord Bot uses WebSocket fallback exclusively

## Data Flow Architecture

### Standard WebRTC Flow

```mermaid theme={null}
sequenceDiagram
    participant Client as Ecosystem Client
    participant Server as Signaling Server
    participant Peer as Remote Peer

    Client->>Server: Connect WebSocket
    Server-->>Client: Connected

    Client->>Server: Request peer list
    Server-->>Client: Send peer list

    Client->>Server: Send WebRTC offer
    Server->>Peer: Forward offer

    Peer->>Server: Send WebRTC answer
    Server->>Client: Forward answer

    Client->>Server: Send ICE candidates
    Server->>Peer: Forward ICE candidates

    Peer->>Server: Send ICE candidates
    Server->>Client: Forward ICE candidates

    Client->>Peer: P2P DataChannel established
```

### WebSocket Fallback Flow

```mermaid theme={null}
sequenceDiagram
    participant Client as Ecosystem Client
    participant Server as Signaling Server
    participant Peer as Remote Peer

    Client->>Server: WebSocket connection
    Server->>Client: Peer list
    Client->>Server: File transfer request
    Server->>Peer: Relay request
    Peer->>Server: Accept response
    Server->>Client: Relay acceptance
    Client->>Server: File chunks (base64)
    Server->>Peer: Relay chunks
    Peer->>Server: Completion confirmation
    Server->>Client: Relay confirmation
```

## Security Considerations
