InteractionMiddleware

Base class for interaction middleware.

Middleware runs after the dispatcher builds the handler and before the gates, over the handler's own reply surface. Name the kinds in the generic and list the same ones in { kinds }. Several kinds give this.event a union. The discord.js guards narrow it. A catchall reads every repliable kind.

abstract class InteractionMiddleware<
    Kind extends MiddlewareKind = MiddlewareKind
> extends RepliableHandler<InteractionOf<Kind>>

\@RegisterInteractionMiddleware({ kinds: [InteractionKind.Button] })
class Audit extends InteractionMiddleware<InteractionKind.Button> {
    async execute() {
        this.logger.info(this.event.customId);
    }
}

Member visibility

Filter class members by access level.

constructor

Constructs a new instance of the InteractionMiddleware class

InteractionMiddleware(
    event: InteractionOf<Kind>,
    core: Core,
    dispatch: DispatchContext,
    sender: ReplySender
)

Showing members with Protected visibility and higher.

Methods

after()
buildSender()
defer()
delete()
edit()
execute()
followUp()
reply()
send()

Kind

One or more InteractionKind members. Defaults to every repliable kind.

Kind extends MiddlewareKind = MiddlewareKind

core

readonly core: TCore

Inherited from:BaseHandler

dispatch

The bag for this dispatch. Each interaction gets its own. Every handler for one event shares a single bag.

protected readonly dispatch: DispatchContext

Inherited from:BaseHandler

event

protected readonly event: Event

Inherited from:BaseHandler

logger

protected readonly logger: Logger

Inherited from:BaseHandler

routeId

protected readonly routeId: string

Inherited from:RepliableHandler

sender

The reply surface for this interaction. Pass the handler to reply from outside its class.

readonly sender: TSender

Inherited from:RepliableHandler

after()

Runs once the handler settles, newest middleware first. A refusal or a throw still reaches it, since seedcord calls it on every middleware whose execute() started. Implement it to release something this middleware took in execute(), such as a lock or an open span. A throw in here is logged and goes no further.

public async after?(result: DispatchResult): Promise<void>

Parameter: result

How the dispatch ended. Either failure state carries the thrown value on caught.

buildSender()

protected buildSender(
    event: Event,
    core: Core,
    dispatch: DispatchContext
): ReplySender

Inherited from:RepliableHandler

defer()

Show a "thinking" placeholder, then fill it later with edit.

protected async defer(opts?: DeferOpts): Promise<void>

Inherited from:RepliableHandler

delete()

Delete the initial reply or deferred placeholder. Pass a target to delete a message a prior send returned.

protected async delete(target?: TMessage): Promise<void>

Inherited from:RepliableHandler

edit()

Rewrite the initial reply or deferred placeholder. The targeted form rewrites a message a prior send returned.

protected async edit(
    response: ReplyResponse<TNative> | string
): Promise<TMessage>

Inherited from:RepliableHandler

execute()

Holds the main logic of your handler. The dispatcher calls it after the handler's gates pass, so a gate that refuses stops execute() from running.

abstract execute(): Promise<void>

Inherited from:BaseHandler

followUp()

Send a new message once the interaction is acknowledged.

protected async followUp(
    response: ReplyResponse<TNative> | string,
    opts?: SendOpts
): Promise<TMessage>

Inherited from:RepliableHandler

reply()

Send the initial response, exactly once.

protected async reply(
    response: ReplyResponse<TNative> | string,
    opts?: SendOpts
): Promise<TMessage>

Inherited from:RepliableHandler

send()

Routes to reply, followUp, or edit based on the current ack state.

protected async send(
    response: ReplyResponse<TNative> | string,
    opts?: SendOpts
): Promise<TMessage>

Inherited from:RepliableHandler
