Any TypeScript definitions for this?

Hm. I don’t see any. Do you?

[VictorioBerra]

many times they are community provided, or stored in a separate module/repository.

I would like to have some so maybe we can add a help wanted label and if anyone has created a few for use in their own projects they can link them here.

Here is a start for the promise side:

declare module 'concurrent-queue' {

    interface LimitConfig {
        concurrency?: number;
        maxSize?: number;
        softMaxSize?: number;
    }

    export default function cq(): cqImpl;

    export interface cqImpl {
        process(processor: (task: any) => Promise<any>): queue;
        limit(limitConfig: LimitConfig): cqImpl;
    }

    export interface queue {
        (item: any): Promise<any>;
    }

}

Thanks @VictorioBerra. If anyone else needs this, I got this down to:

declare module 'concurrent-queue' {
  interface LimitConfig {
    concurrency?: number;
    maxSize?: number;
    softMaxSize?: number;
  }

  export default function cq(): Queue<any>;

  export interface Queue<T> {
    process<T>(processor: (task: any) => Promise<T>): Queue<T>;
    limit(limitConfig: LimitConfig): Queue<T>;
    (item: any): Promise<T>;
    /** the number of queued items */
    size: number;
    pending: T[];
    drained: (cb: () => void) => void;
    processingEnded: (cb: () => void) => void;
  }
}

which better reflects the two fluent methods (it's just as valid to call process() before limit), and ensures the process() call returns a typed Queue<T>, which in turn means queue(item) returns a promise of the same type as the func passed to process()

@jasonpincin would you be interested in a PR to add these (to be completed) Typescript defs?

[jasonpincin]

@bentorkington Yes! Thank you!
