Deno Twitch Message Interface

this package is very similar to tmi.js but for Deno. This package is still very early in development.

What it does

tmi.ts allows you to create bots and automate tasks in a users Twitch Chat.

What you need in order to use

1. OAuth token – https://twitchapps.com/tokengen/ – make sure that your app’s redirect url matches the websites redirect url
2. Twitch Client ID
3. Your Twitch username in lower-case

Quick Example

import { TwitchChat, Channel } from "https://deno.land/x/tmi/mod.ts";
import { delay } from "https://deno.land/std@0.64.0/async/delay.ts";

const tc = new TwitchChat(oauth, username);

await tc.connect();

tc.addEventListener("whisper", (whisper) => {
     // Do something with whisper here
})

const channel = tc.joinChannel("xqcow");

channel.addEventListener("privmsg", (ircMsg) => {
  if (ircMsg.message.contains("badword")) {
   channel.commands.ban(ircMsg.username)
  } else if (ircMsg.directMsg) {
    console.log(`You have been messaged by ${ircMsg.username}`)
  }
);

await delay(60000);

tc.exit();

TwitchChat

Allows you to connect to Twitch’s chat, listen to private whispers and more

• .connect()

  Connects to Twitch’s secure WebSocket endpoint wss://irc-ws.chat.twitch.tv:443. Returns a promise that resolves when the user has correctly authenticated else it rejects.

• .joinChannel(channel: string)

  Joins the channel that it’s given as a parameter. Returns a promise.

• .exit()

  Parts all channels that have been joined, cleans up everything in the Event Loop and closes connection to Twitch’s websocket.

• channels: Map<string, Channel>

  A Map for all channels that are currently joined. If a channel is parted it will also delete itself from this Map.

• .addEventListener(event: TwitchChatEvents, (msg: IrcMessage) => void)

  Handle specific events outside the scope of a channel like, whispers, notices, and pings etc. Events are specific strings which TypeScript should help you out with.

Channel

Listen to specific events of a channel or part it (leave the channel).

• .send(message: string)

  Send a message to the channels chat.

• .part()

  Leave the channel, deletes itself from channels Map in TwitchChat, and resolves all of its promises in event loop.

• .channelOwnerName: string

  Returns the username of the owner of the chat. For example, if I join “ninja” chat, it will return “ninja”.

• .commands

  These are commands that can be used in a twitch chat. Note that certain commands require certain scopes in your oauth token `. For more information about these commands visit: twitch’s docs

• .addEventListener(event: ChannelEvent, (msg: IrcMsg) => void)

  Handle events such as privmsg, joins, roomstate etc.

  Tip: privmsg is the event which handles chat messsages
