Kasai

Kasai serves as a bridge between Discord and Twitch, allowing a single bot to interact with both platforms.

This serves to extend Hikari, and cannot be used without it.

Installation

To install the latest released version of Kasai, use the following command:

pip install hikari-kasai

You can also install the latest development version using the following command:

pip install git+https://github.com/parafoxia/hikari-kasai

You may need to prefix these commands with a call to the Python interpreter depending on your OS and Python configuration.

Creating your bot

Kasai provides a subclass for hikari.GatewayBot that contains methods and attributes for Twitch chat interfacing.

import kasai

bot = kasai.GatewayBot(...)

To use Kasai with command handlers, you will need to create a custom subclass that inherits from both kasai.GatewayBot and your command handler's bot class. For example, if you want to use Lightbulb:

import kasai
import lightbulb

class Bot(kasai.GatewayBot, lightbulb.BotApp):
    ...

bot = Bot(...)

Usage

A working implementation could look something like this:

import os

import dotenv
import hikari
import kasai

# You will need a .env file for this.
dotenv.load_dotenv()

# Create the bot.
bot = kasai.GatewayBot(
    os.environ["TOKEN"],
    os.environ["IRC_TOKEN"],
    os.environ["TWITCH_CLIENT_ID"],
    os.environ["TWITCH_CLIENT_SECRET"],
)

@bot.listen(hikari.StartedEvent)
async def on_started(event: hikari.StartedEvent):
    # Connect to your Twitch chat.
    await bot.twitch.join("twitchdev")

@bot.listen(hikari.GuildMessageCreateEvent)
async def on_message(event: hikari.GuildMessageCreateEvent):
    # Send a message from Discord to Twitch chat.
    if event.content.startswith("!send"):
        await bot.twitch.create_message("twitchdev", event.content[6:])

@bot.listen(kasai.MessageCreateEvent)
async def on_twitch_message(event: kasai.MessageCreateEvent):
    # Basic Twitch command implementation.
    if event.content.startswith("!ping"):
        await event.message.respond("Pong!", reply=True)

# Run the bot.
bot.run()

There are more examples should you wish to see them. It may also be worth looking into how to speed Hikari up to get the best performance out of Kasai.
