What are the advantages and disadvantages of using libraries for WebSocket?

Advantages of using libraries for WebSocket work:

• Simplified development: Libraries provide ready-made methods for establishing connections, sending and receiving messages, handling errors, and reconnecting.
• Cross-platform compatibility: Many libraries support different platforms and iOS versions, making maintenance easier.
• Optimization and stability: Libraries are often optimized and tested, reducing the likelihood of errors.
• Additional features: For example, support for security protocols, automatic reconnection, message queue management.

Disadvantages:

• Dependence on third-party code: Bugs or outdated libraries may occur.
• Application size: Including large libraries increases the app size.
• Limited flexibility: Sometimes, a library may not allow implementing specific requirements.
• Updates and compatibility: Updating iOS or servers may cause compatibility issues.

Example of using the Starscream library for WebSocket in iOS:

import Starscream

class WebSocketManager: WebSocketDelegate {
    var socket: WebSocket!

    init() {
        var request = URLRequest(url: URL(string: "wss://example.com/socket")!)
        socket = WebSocket(request: request)
        socket.delegate = self
        socket.connect()
    }

    func websocketDidConnect(socket: WebSocketClient) {
        print("Connected")
    }

    func websocketDidDisconnect(socket: WebSocketClient, error: Error?) {
        print("Disconnected: \(error?.localizedDescription ?? "no error")")
    }

    func websocketDidReceiveMessage(socket: WebSocketClient, text: String) {
        print("Received text: \(text)")
    }

    func websocketDidReceiveData(socket: WebSocketClient, data: Data) {
        print("Received data: \(data.count) bytes")
    }
}
