# Luzifer / twitch-bot
Twitch-Bot is intended as an alternative to having a bot managed by Streamlabs or Streamelements and therefore having more control over it, the availability and how it works.
At the moment it is a work-in-progress and does not yet implment all features it shall in the future.

Please see the [Wiki](https://github.com/Luzifer/twitch-bot/wiki) for documentation of the configuration file.

### Database Connection Strings
Currently these databases are supported and need their corresponding connection strings:
#### MySQL
```
[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]
Recommended parameters:
?charset=utf8mb4&parseTime=True&loc=Local
```
- Create your database as follows:
```sql
CREATE DATABASE twbot_tezrian DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_unicode_ci;
```
- Start your bot:
```console
# twitch-bot \
--storage-conn-type mysql \
--storage-conn-string 'tezrian:mypass@tcp(mariadb:3306)/twbot_tezrian?charset=utf8mb4&parseTime=True&loc=Local' \
...
```
See [driver documentation](https://github.com/go-sql-driver/mysql#dsn-data-source-name) for more details on parameters.
#### Postgres
```
host=localhost port=5432 dbname=mydb connect_timeout=10
```
See [Postgres documentation](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS) for more details in paramters.
#### SQLite
```
storage.db
```
Just pass the filename you want to use.
- Start your bot:
```console
# twitch-bot \
--storage-conn-type sqlite \
--storage-conn-string 'storage.db' \
...
```
