Alerts

Anomalist subscribes to Twitch EventSub and can react on the overlay when someone follows, subscribes or raids you.

What is supported

Event	Default duration
Follow	3 seconds
Subscription	5 seconds
Raid	8 seconds

Configuring an alert

For each event you can set:

• Sound — a file from your media library, played through the overlay when the event fires.
• Widget — a widget to reveal for the duration of the alert. Anything on the canvas works: a text banner, an image, a particle burst.
• Duration — how long the widget stays visible, in seconds.

Leaving a field empty simply skips that part, so you can have a sound with no visual, or a visual with no sound.

How it reaches the overlay

Alerts arrive over the same authenticated socket connection as everything else, so they show up without a page reload and without polling. If the EventSub connection drops, Anomalist reconnects on its own.

Requirements

• Twitch must be connected — see Connecting Twitch.
• Configuring alerts requires the stream.manage permission, which owners have by default. Editors and moderators do not.

Testing without waiting for a real event

The simplest check is to trigger the pieces directly: play the alert's sound from the soundboard, and toggle the alert widget's visibility on the canvas. If both work, the alert will work — what EventSub adds is only the trigger.
