@marianmeres/ttl-queue v1.0.1

@marianmeres/ttl-queue

Add things to queue and have them dequeue sequentially based on their defined expiration (ttl). Read head of the queue as a store value.

Install

$ npm i @marianmeres/ttl-queue

Example usage

import { createTtlQueueStore } from '@marianmeres/ttl-queue';

// using plain strings here as an example, but the enqueued value can be anything
const q = createTtlQueueStore<string>();

// fictional example
const unsub = q.subscribe((head) => screen.show(head));

q.enqueue('one', 1_000);
q.enqueue('two', 2_000);
q.enqueue('three', 3_000);

// in this example the fictional "screen" module above will show
// "one" for 1 second, then "two" for 2 seconds and finally "three" for 3 seconds.
// An then it will be undefined until another `q.enqueue(...)` comes.
