HandlerFunction

The HandlerFunction type represents the core logic for any interaction handler. It is the function that gets executed when a specific interaction matches a registered handler.

Definition

export type HandlerFunction<
  Context extends BaseInteractionContext = BaseInteractionContext,
  InteractionArg extends AnyInteraction<Context> = AnyInteraction<Context>,
> = (interaction: InteractionArg) => Promise<any> | any;

Description

A HandlerFunction receives an interaction object (which includes the context) and can perform any logic required. It typically returns a promise, but can also be synchronous.

Properties of InteractionArg

The InteractionArg will be one of the interaction classes (e.g., ChatInputCommandInteraction, ButtonInteraction, etc.) depending on what the handler is registered for.

All interaction arguments share a c (context) property which is the BaseInteractionContext.
