TwitchLib.EventSub.Websockets
TwitchLib component to connect to Twitch's EventSub service via Websockets also known as EventSockets
Disclaimer
EventSub via Websockets is still in open beta. You can use it in production but Twitch may introduce breaking changes without prior notice. The same goes for this implementation until it reaches Version 1.0.0

Setup
Step 1: Create a new project (Console, WPF, ASP.NET)
Step 2: Install the TwitchLib.EventSub.Websockets nuget package. (See above on how to do that)
Step 3: Step 3: Add necessary services and config to the DI Container
services.AddTwitchLibEventSubWebsockets();
services.AddHostedService<WebsocketHostedService>();
(The location of where to put this and the naming of variables might differ depending on what kind of project and general setup you have)
Step 4: Create the HostedService we just added to the DI container and connect to EventSub and listen to Events
using System.Net.Http.Headers;
using System.Text;
using System.Text.Json;
using TwitchLib.EventSub.Websockets.Core.EventArgs;
using TwitchLib.EventSub.Websockets.Core.EventArgs.Channel;
namespace TwitchLib.EventSub.Websockets.Test
{
public class WebsocketHostedService : IHostedService
{
private readonly ILogger<WebsocketHostedService> _logger;
private readonly EventSubWebsocketClient _eventSubWebsocketClient;
public WebsocketHostedService(ILogger<WebsocketHostedService> logger, EventSubWebsocketClient eventSubWebsocketClient)
{
_logger = logger ?? throw new ArgumentNullException(nameof(logger));
_eventSubWebsocketClient = eventSubWebsocketClient ?? throw new ArgumentNullException(nameof(eventSubWebsocketClient));
_eventSubWebsocketClient.WebsocketConnected += OnWebsocketConnected;
_eventSubWebsocketClient.WebsocketDisconnected += OnWebsocketDisconnected;
_eventSubWebsocketClient.WebsocketReconnected += OnWebsocketReconnected;
_eventSubWebsocketClient.ErrorOccurred += OnErrorOccurred;
_eventSubWebsocketClient.ChannelFollow += OnChannelFollow;
}
public async Task StartAsync(CancellationToken cancellationToken)
{
await _eventSubWebsocketClient.ConnectAsync();
}
public async Task StopAsync(CancellationToken cancellationToken)
{
await _eventSubWebsocketClient.DisconnectAsync();
}
private void OnWebsocketConnected(object? sender, WebsocketConnectedArgs e)
{
_logger.LogInformation($"Websocket {_eventSubWebsocketClient.SessionId} connected!");
if (!e.IsRequestedReconnect)
{
// subscribe to topics
}
}
private async void OnWebsocketDisconnected(object? sender, EventArgs e)
{
_logger.LogError($"Websocket {_eventSubWebsocketClient.SessionId} disconnected!");
// Don't do this in production. You should implement a better reconnect strategy with exponential backoff
while (!await _eventSubWebsocketClient.ReconnectAsync())
{
_logger.LogError("Websocket reconnect failed!");
await Task.Delay(1000);
}
}
private void OnWebsocketReconnected(object? sender, EventArgs e)
{
_logger.LogWarning($"Websocket {_eventSubWebsocketClient.SessionId} reconnected");
}
private void OnErrorOccurred(object? sender, ErrorOccuredArgs e)
{
_logger.LogError($"Websocket {_eventSubWebsocketClient.SessionId} - Error occurred!");
}
private void OnChannelFollow(object? sender, ChannelFollowArgs e)
{
var eventData = e.Notification.Payload.Event;
_logger.LogInformation($"{eventData.UserName} followed {eventData.BroadcasterUserName} at {eventData.FollowedAt}");
}
}
}
