hibiki-discord 1.0.1

Lean Discord notification service for business events

Hibiki Discord

A lean Discord notification service for business events. Define notification types in a TOML config file, store webhook URLs in environment variables, and send notifications with one function call.

Installation

pip install hibiki-discord

Quick start

1. Create a config file (hibiki-discord.toml in your project root):

[notifications.user_signup]
webhook_url_env = "SIGNUP_DISCORD_WEBHOOK_URL"
username = "Signup Bot"
message_template = "New user signed up: {email}"

[notifications.subscription]
webhook_url_env = "SUBSCRIPTION_DISCORD_WEBHOOK_URL"
username = "Billing Bot"
message_template = "New {plan} subscription by {email}"

webhook_url_env is the name of the environment variable that holds the webhook URL. The TOML file contains no secrets and is safe to commit.

2. Set your webhook URLs as environment variables (e.g. in your .env file or deployment config):

• SIGNUP_DISCORD_WEBHOOK_URL=https://discord.com/api/webhooks/...
• SUBSCRIPTION_DISCORD_WEBHOOK_URL=https://discord.com/api/webhooks/...

3. Send notifications:

from hibiki_discord import load_config, send_notification, fire_notification

load_config()  # reads hibiki-discord.toml

# Await the result (blocks the caller until sent)
await send_notification("user_signup", email="[e-mail]")

# Fire-and-forget (returns immediately, sends in the background)
fire_notification("subscription", plan="Pro", email="[e-mail]")

Emails are automatically anonymized in messages (e.g. j***@example.com).

Configuration

TOML config file

Each [notifications.<name>] section defines a notification type:

Key	Required	Default	Description
webhook_url_env	Yes	-	Name of the env var holding the Discord webhook URL
message_template	Yes	-	Python format string for the message
username	No	-	Display name for the Discord bot
enabled	No	true	Set to false to disable this notification type

Config file location

By default, load_config() looks for hibiki-discord.toml in the current working directory. Override with:

• Pass a path: load_config("/path/to/config.toml")
• Set the HIBIKI_DISCORD_CONFIG env var: export HIBIKI_DISCORD_CONFIG=/path/to/config.toml

Programmatic configuration

Skip the TOML file and configure in Python:

from hibiki_discord.config import load_config_from_dict

load_config_from_dict({
    "user_signup": {
        "webhook_url_env": "DISCORD_SIGNUP_WEBHOOK",
        "username": "Signup Bot",
        "message_template": "New user: {email}",
    },
})

API reference

load_config(path=None) -> dict

Load notification config from a TOML file. Returns a dict of notification type name to config.

send_notification(notification_type, **template_vars) -> bool

Send a notification. Looks up the config, resolves the webhook URL from env, formats the template, and sends. Returns True on success. Raises ValueError if the type is unknown or the template is missing.

fire_notification(notification_type, **template_vars) -> asyncio.Task[bool]

Fire-and-forget variant of send_notification. Schedules the notification as a background task on the running event loop and returns immediately. Errors are logged instead of raised. The returned asyncio.Task can be awaited if you need the result, or simply ignored.

send(webhook_url, message, username=None) -> bool

Low-level send. Posts a message directly to a Discord webhook URL.

get_notification_config(notification_type) -> NotificationConfig | None

Get the config for a specific notification type, or None if not configured.
