VodOnDemand.TwitchEverywhere.Irc 0.9.0

TwitchEverywhere.Irc

TwitchEverywhere.Irc is a .NET library that allows connecting to a Twitch chat using IRC 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. TwitchEverywhere.Irc uses Rx.NET to provide a reactive API for handling messages from Twitch.

The library will support the latest LTS version of .NET and non LTS versions IF it is newer than the LTS version. So for example before .NET 8, the library supported .NET 6 (LTS) and 7 but once .NET 8 was released support for 6 and 7 was dropped.

How To Use It

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

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

Next create an instance of the IrcClient and pass in the options to the constructor.

internal class TwitchConnection(
    TwitchConnectionOptions options
) {
    private readonly IrcClient m_ircClient = new( options );
    
    // implementation
}

Then define a method that will consume the observables returned from TwitchEverywhere. Each message type has its own observable that you can subscribe to and it will return a strong type.

// This example only handles MessageType.PrivMsg but you can handle other types here too
public async Task ConnectToIrcClientRx() {
    
    // TaskCompletionSource is only needed for the CLI app to prevent it from exiting early
    TaskCompletionSource<bool> tcs = new();

    IrcClientObservable observable = m_ircClient.ConnectToChannelRx();

    IDisposable privObservable = observable.PrivMsgObservable.Subscribe( 
        msg => PrivMessageCallback(msg)
    );

    try {
        await tcs.Task;
    } finally{
        joinObservable.Dispose();
        privObservable.Dispose();
    }
}

Now whenever TwitchEverywhere receives a message it will pass it to the appropriate observable 🎉

Sample CLI App

There is a sample CLI application here 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"
}
