# Luzifer / twitch-bot-streak
Addon for my [twitch-bot](https://github.com/Luzifer/twitch-bot) executed through the [Execute Script / Command](https://luzifer.github.io/twitch-bot/configuration/actors/#execute-script--command) action to build a custom watch-streak feature.
## Features
- By default uses same database connection as the bot through the same environment variable
- Needs two tables (see `schema.sql`) to store its data
- Reward is only counted once per stream (in case Twitch messes up stuff)
- If a stream goes offline for a few minutes a grace period (30m) is taken which will not reset the stream streak
## Usage
The program is used by three rules to register the `stream_online` and `stream_offline` events and to count user presence through a `channelpoint_redeem`:
```yaml
