ComponentHandler

Shared base the customId-routed component handlers extend.

Not a public entry point. Extend ButtonHandlerButtonHandler, SelectMenuHandlerSelectMenuHandler, or ModalHandlerModalHandler instead. This class defines the customId decode and the route matching those bases share.

abstract class ComponentHandler<
    Event extends ComponentInteraction,
    Defs extends readonly AnyCustomId[]
>
    extends InteractionHandler<Event>
    implements HasComponentDefs<Defs>

params

The decoded params of the single route this handler is registered for.

Reading this decodes this.event.customIdthis.event.customId once (cached after the first read) and throws StaleCustomIdStaleCustomId or InvalidCustomIdInvalidCustomId when the wire no longer matches the current shape, which the controller boundary turns into a reply. On a handler registered for several routes this is nevernever, so use matchmatch instead.

deferUpdate()

Acknowledge the component without changing the source message.

protected async deferUpdate(): Promise<void>

protected async deferUpdate(): Promise<void>

match()

Run the arm for whichever route the component was minted from. Use this only when the handler is registered for several routes. A single-route handler reads this.paramsthis.params directly. On a multi-route handler this.paramsthis.params is nevernever, so match is the only way to read the decoded params.

Provide one arm per registered route, keyed by its prefix, and each arm receives that route's own decoded params. The arms cover every registered route prefix, checked at compile time, and a prefix unmatched at runtime throws CustomIdMatchArmMissingCustomIdMatchArmMissing. Decoding runs before any arm, so a stale or corrupt wire throws before an arm body executes.

Parameter: arms

One callback per registered route, keyed by prefix.

    async execute() {
        await this.match({
            approve: ({ userId }) => this.reply(`approved <@${userId}>`),

            reject: ({ userId }) => this.reply(`rejected <@${userId}>`)
        });
    }
}

showModal()

Open a modal. Must be the initial response to this interaction. The modal kind rejects this call at compile time (Discord forbids a modal in response to a modal).
