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 implementing custom websocket client

App.tsx

package com.example.demosilentshard

import com.silencelaboratories.silentshard.duo.initiator.network.DuoNetworkAction
import com.silencelaboratories.silentshard.duo.initiator.network.DuoNetworkClient
import com.silencelaboratories.silentshard.network.websocket.WebsocketConfig
/**
 * This class could be extended to add custom logic before or after any websocketClient
 * operations such as connecting, read, etc. Or users are open to use their own version of
 * websocket client by extending NetworkClient interface.*/
class CustomNetworkClient(websocketConfig: WebsocketConfig) : DuoNetworkClient(websocketConfig) {

    override suspend fun connect(
        action: DuoNetworkAction, params: String?,
    ) {
        val customAction = when (action) {
            is DuoNetworkAction.ECDSA.Import -> {
                action
            }

            is DuoNetworkAction.ECDSA.KeyRefresh -> {
                action
            }

            is DuoNetworkAction.ECDSA.Keygen -> {
                DuoNetworkAction.ECDSA.Keygen(path = "custom-path-for-keygen")
            }

            is DuoNetworkAction.ECDSA.Reconcile -> {
                action
            }

            is DuoNetworkAction.ECDSA.Signature -> {
                action
            }

            is DuoNetworkAction.EdDSA.Import -> {
                action
            }

            is DuoNetworkAction.EdDSA.KeyRefresh -> {
                action
            }

            is DuoNetworkAction.EdDSA.Keygen -> {
                action
            }

            is DuoNetworkAction.EdDSA.Reconcile -> {
                action
            }

            is DuoNetworkAction.EdDSA.Signature -> {
                action
            }
        }

        super.connect(customAction, params)
    }
