Variable middlewareConst

Type Declaration

• • <
        Params extends
            Partial<Record<string, string>> = Partial<Record<string, string>>,
        RouteId extends string
        | null = string | null,
        Functions extends
            MiddlewareFunction<Params, RouteId, object>[] = MiddlewareFunction<
            Params,
            RouteId,
            object,
        >[],
        FunctionReturns extends
            void
            | object
            | {}
            | void & {}
            | undefined = Awaited<ConcatReturnTypes<Functions>>,
    >(
        handle: MiddlewareServiceHandler<Params, RouteId, FunctionReturns>,
        ...middlewares: Functions,
    ): (event: ServiceRequestEvent<Params, RouteId>) => Promise<Response>

  • Compose a service handler with one or more middleware functions.

    Middleware functions run in order. Each may return an object to be merged into event.guard. If any middleware throws/returns a Response via error handling, the pipeline short-circuits.

    Type Parameters

    • Params extends Partial<Record<string, string>> = Partial<Record<string, string>>
    • RouteId extends string | null = string | null
    • Functions extends MiddlewareFunction<Params, RouteId, object>[] = MiddlewareFunction<Params, RouteId, object>[]
    • FunctionReturns extends void | object | {} | void & {} | undefined = Awaited<ConcatReturnTypes<Functions>>

    Parameters

    • handle: MiddlewareServiceHandler<Params, RouteId, FunctionReturns>
    • ...middlewares: Functions

    Returns (event: ServiceRequestEvent<Params, RouteId>) => Promise<Response>
