Installation

pip install sonora-musicpy

Quickstart

First, set up your environment variables:

cp .env.example .env
# Edit .env with your Lavalink server details and Discord token

Minimal Discord Bot Example

import discord
from discord.ext import commands
from sonora import SonoraClient

intents = discord.Intents.default()
intents.message_content = True

bot = commands.Bot(command_prefix='!', intents=intents)
sonora = SonoraClient(
    lavalink_nodes=[{"host": "127.0.0.1", "port": 2333, "password": "youshallnotpass"}],
    node_pooling=True,
    reconnect_policy={"max_retries": 5, "backoff": "exponential"}
)

@bot.event
async def on_ready():
    await sonora.start()
    print(f'Logged in as {bot.user}')

@bot.command()
async def join(ctx):
    if ctx.author.voice:
        await ctx.author.voice.channel.connect()
        player = await sonora.get_player(ctx.guild.id)
        await ctx.send("Joined voice channel!")
    else:
        await ctx.send("You need to be in a voice channel!")

@bot.command()
async def play(ctx, *, query):
    player = await sonora.get_player(ctx.guild.id)
    track = await player.play(query)
    await ctx.send(f"Now playing: {track.title}")

bot.run(os.getenv('DISCORD_TOKEN'))
