Custom WebSocket client

Overview

The DuoNetworkClient class is a WebSocket client operations implements transport agnostic NetworkClient.

1. DuoNetworkClient implements NetworkClient

• Responsibility:
  • Raw WebSocket connection management
  • Message queueing and asynchronous I/O
  • Binary/text data transmission
• Customization Use Cases:
  • Add Action specific logic for example perform some logic on keygen connect
  • Replace WebSocket library (e.g., Socket.IO, different WebSocket impl)
  • Modify low-level message queueing logic

Example

App.tsx

import duoinitiator

class CustomNetworkClient: DuoNetworkClient {

    override func connect(websocketAction: DuoNetworkAction, params: String?) async throws {
        var customAction: WebsocketAction = websocketAction

        // Customize the action based on the specific type
        if var keygenAction = websocketAction as? ECDSAKeygen {
            // Example: Customize path, action, or protocol
            keygenAction.path = "custom-duo"
            customAction = keygenAction
        } else if var keygenAction = websocketAction as? EdDSAKeygen {
            // Example: Customize path, action, or protocol
            keygenAction.path = "custom-duo"
            customAction = keygenAction
        } else if var signAction = websocketAction as? ECDSASignature {
            // Example: Customize signature action
            signAction.protocol = "custom-duo-instance"
            customAction = signAction
        } else if var signAction = websocketAction as? EdDSASignature {
            // Example: Customize signature action
            signAction.protocol = "custom-duo-instance"
            customAction = signAction
        }
        // Add more customizations as needed for other action types

        try await super.connect(
            websocketAction: customAction as! DuoNetworkAction,
            params: params
        )
    }
}
