This repo contains functions that makes it easy to program with AsyncGenerators in a functional programming friendly way.

API

• flatten <T>(array: AsyncGenerator<T, any, unknown>[]) => AsyncGenerator<T, void, unknown>

• generate <T, R>(fn: (el: T, index?: number, arr?: T[]) => Promise<R>) => (arr: T[]) => AsyncGenerator<R, void, unknown>

• iterate

    interface IterateFn<T> {
        each?: EachFn<T>
        done?: DoneFn<T>
    }
    type EachFn<T> = (yielded?: T, index?: number) => Promise<any>
    type DoneFn<T> = (yieldedArray?: T[]) => Promise<any>

  <T>(generator: AsyncGenerator<T, any, unknown>) => (fn: IterateFn<T>) => Promise<void>

• iterateSync eachFn and doneFn are synchronous function rather than returning a promise.
