TwitchEverywhere is a .NET Core (6 and 7) library that allows connecting to a Twitch chat and subscribing to messages in that chat.

The goal of this library is to provide a lightweight, strongly typed API for clients so they can avoid parsing raw strings as much as possible. Additionally, Twitch requires an authenticated connection to the IRC server which can get a bit complicated to setup and maintain. Fortunately TwitchEverywhere can do that for you! 😀

If you are planning on using TwitchEverywhere on AWS I suggest using .NET 6 for compatibility reasons.

How To Use It

You will need to provide the following values as parameters to the TwitchConnectionOptions record:

TwitchConnectionOptions options = new(
    Channel: channel,
    AccessToken: accessToken,
    RefreshToken: refreshToken,
    ClientId: clientId,
    ClientSecret: clientSecret,
    ClientName: clientName
);

Next define a MessageCallback method that will handle any messages that TwitchEverywhere sends to your application. The input will be of type TwitchEverywhere.Types.Message and return type void.

// This example only handles MessageType.PrivMsg but you should handle other types here too
private void MessageCallback( Message message ) {
    switch( message.MessageType ) {
        case MessageType.PrivMsg: {
            PrivMsg privMsg = (PrivMsg) message;
            PrivMessageCallback( privMsg );
            break;
        }
        default:
            // This is just an example, you can handle this case however you wish
            throw new ArgumentOutOfRangeException();
    }
}

Then initialize TwitchEverywhere and pass in the options to the constructor. Finally call the TwitchEverywhere.ConnectToChannel method and pass in your callback as a parameter.

TwitchEverywhere.TwitchEverywhere twitchEverywhere = new( options );
await twitchEverywhere.ConnectToChannel( MessageCallback );

Now whenever TwitchEverywhere receives a message it will pass it to your callback! 🎉

Sample CLI App

There is a sample CLI application that is included as an example in this repo and you can use it to connect with Twitch – give it a try!

In order to connect you need to create an appsettings.json file in the root of the TwitchEverywhereCLI project with the following parameters:

{
  "AccessToken": "your_twitch_access_token",
  "RefreshToken": "your_twitch_refresh_token",
  "ClientId": "your_client_id",
  "ClientSecret": "your_client_secret",
  "ClientName": "your_client_name_all_lowercase",
  "Channel": "channel_you_want_to_connect_to"
}

Performance

The benchmarks in the TwitchEverywhere.Benchmark project use the BenchmarkDotNet library. You can read more about the methodology that BenchmarkDotNet uses here.

We send 500 messages of each type to TwitchEverywhere and run it several times to determine an average. The results are below:
