sequencer - a deno 🦕 module for sequential promises

Deno promise sequencing.

Usage

To execute promises sequentially, simply add the functions returning the promises to an array, and call await seq(array). Your promises will be executed one sequentially! 🦕

import { seq } from "https://deno.land/x/sequencer/mod.ts";

const sleep = (t: number) => new Promise((res) => setTimeout(res, t));

let acc: Array<number> = [];
await seq([
  () => sleep(10).then(() => acc.push(1)),
  () => sleep(20).then(() => acc.push(2)),
  () => sleep(1).then(() => acc.push(3)),
]);

console.log(acc); // > [ 1, 2, 3 ]
