kichat.js

A robust JavaScript library to connect to Kick.com's chat, designed to work seamlessly in both Node.js and browser environments.

• Isomorphic: Works in Node.js and modern browsers out-of-the-box.
• Robust Connections: Automatic reconnection with configurable exponential backoff.
• Event-Driven: Clean, event-based architecture for handling chat interactions.
• Fully Typed: Written in TypeScript for a better developer experience.
• Rich Data: Provides detailed channel and chatroom information upon joining.

npm i kichat.js

import { KickChat } from 'kichat.js';

const client = new KickChat();

client.on('connected', () => {
	console.log('Successfully connected to Kick!');
	// Join a channel after connecting
	client.join('xqc');
});

client.on('join', (channel) => {
    console.log(`Joined channel: ${channel.slug}`)
});

client.on('message', (message, channel) => {
	console.log(`[${channel.slug}] ${message.sender.username}: ${message.content}`);
});

// Start the connection
client.connect();

The library is available on the window object as kickChat.

<script src="https://cdn.jsdelivr.net/npm/kichat.js/dist/kichat.js.browser-global.min.js"></script>
<script>
    const client = new kichat.KiChatjs()
    client.on('connected', () => console.log('Connected!'));
    client.on('join', (data) => console.log(`Successfully joined channel: ${data.info.slug}`))
    client.connect();
    client.join('xqc');

Creates a new client instance.

Options:

• channels (string[], optional): An array of channel slugs to automatically join upon connection.
• reconnect (boolean, optional, default: true): Whether the client should attempt to reconnect automatically if the connection is lost.
• reconnectMaxAttempts (number, optional, default: Infinity): Maximum number of reconnection attempts.
• reconnectInitialTimeout (number, optional, default: 1000): The initial time to wait in milliseconds before the first reconnection attempt.
• reconnectMaxTimeout (number, optional, default: 60000): The maximum time to wait in milliseconds between reconnection attempts.
• subscribePusher ({ channel: boolean, chatRoom: boolean, predictions: boolean }, optional, default: true): With this you can choose which events you want to connect in the pusher, if you only want chat messages you can enable only the chatRoom

• .connect(): Establishes the connection to Kick's WebSocket server. This must be called to start receiving events.

• .close(): Cleanly disconnects the client.

• .isConnected(): Checks if the websocket is connected.

• .join(channelName): Asynchronously joins a chat channel. Returns a Promise which resolves with the Channel object upon successful join confirmation from the server.

  • channelName (string): The slug of the channel to join (e.g., 'xqc').

• .leave(channelName): Leaves a chat channel.

  • channelName (string): The slug of the channel to leave from.

• .fetchUserInfo(channelName): Get user data from api.

  • channelName (string): The slug of the channel to fetch.

• .fetchChatRoom(channelName): Get chat room data from api.

  • channelName (string): The slug of the channel to fetch.

Listen to events using client.on('eventName', (arg1, arg2, ...) => { ... });

• connected: Fired when the WebSocket connection is successfully established.
• disconnected (reason: string): Fired when the client is disconnected.
• reconnecting: Fired when the client is attempting to reconnect after an unexpected disconnection.
• join (channel: Channel): Fired when the client successfully subscribes to a channel's events.
• leave (channel: Channel): Fired when the client leaves a channel.
• error (error: Error): Fired when an error occurs.

All channel-specific events return the Channel object as the last parameter, which contains rich data about the channel and its chatroom settings.

Contributions are welcome! Please feel free to open an issue to discuss what you would like to change or submit a Pull Request.

Here are some features and improvements planned for the future:

• Send Chat Messages: Implement a .say(channel, message) method to send messages to a chatroom. This will likely require handling user authentication.
• Authentication: Add support for authenticating as a Kick user to perform actions on their behalf (like sending messages or performing moderation actions).
• Moderation Methods: Implement methods for moderators, such as .ban(), .unban(), .timeout(), and .deleteMessage().
• Add a Testing Framework: Integrate a testing framework like Jest or Vitest to ensure code quality and stability.
• CI/CD Workflow: Set up a GitHub Actions workflow to automatically run tests and builds on push/pull request.
• Complete TSDoc Documentation: Add detailed TSDoc comments to all public methods and interfaces for improved IntelliSense and auto-generated documentation.
