discorddaemon (ddd)

Discord daemon with per-channel hooks. UNIX philosophy for Discord bots.

One daemon, many hooks. Each Discord channel routes to its own script. Your hook receives a message on stdin, writes a reply to stdout. That's it.

Requirements

• Bun >= 1.3.10

Install

bun install -g discorddaemon

Quick Start

First time? See the Setup Guide for step-by-step instructions from bot creation to channel configuration.

1. Create a Discord bot at Discord Developer Portal and grab the token.

2. Scaffold config and hooks:

ddd init    # creates ~/.config/ddd/ddd.toml and hooks/

3. Edit ~/.config/ddd/ddd.toml:

[bot]
token = "YOUR_BOT_TOKEN"  # or set DDD_TOKEN env var

[channels.general]
id = "CHANNEL_ID_HERE"
on_message = "./hooks/echo.sh"

4. List available channels (optional):

ddd channels   # shows channel IDs and names as NDJSON

5. Start the daemon:

ddd start

Hook Interface

Hooks are any executable. Shell scripts, Python, Rust binaries — anything that reads stdin and writes stdout.

Input (stdin)

{
  "id": "message_id",
  "channel_id": "123456",
  "channel_name": "general",
  "author": {
    "id": "user_id",
    "username": "someone",
    "bot": false
  },
  "content": "hello world",
  "timestamp": "2026-03-23T12:00:00.000Z",
  "attachments": []
}

Output (stdout)

Plain text. If non-empty, sent as a reply. If empty, nothing happens.

Exit codes

• 0 — success
• non-zero — error logged to stderr

Timeout

30 seconds by default.

Example Hook

#!/usr/bin/env bash
# echo.sh — echoes back the message content
jq -r '.content' | sed 's/^/echo: /'

Design Philosophy

• One tool, one job. ddd connects to Discord. Your hooks do everything else.
• Text streams as interface. stdin JSON in, stdout text out. Composable with any language.
• No framework lock-in. Hooks are processes, not plugins. Swap them without restarting.
