promise-minimum-delay v1.0.3

Why

I often find that I don't want my promises to settle too fast. In the case of making a network request and showing a spinner/loading indicator, if the request finishes too quickly, the spinner/loading UI indicator might flash and disappear. This module aims to settle (pun intended) that, without making use of Promise.settle provided by various Promise libraries.

Why not Promise.settle?

Promise.settle settles with an array. I only ever want the value that my original promise fulfill's with or rejects with, just after a minimum timeout.

Why not Promise.delay?

Various implementations of Promise.delay are inconsistent - they delay the resolve, but not the reject, or they only delay a full amount of time after a promise has resolved. promise-minimum-delay aims to simply require a promise to wait at least the specified delay before it resolves OR rejects. Easy.

Usage

import delayPromise from 'promise-minimum-delay';

let p = Promise.resolve(1); //or something else that returns a promise, like a network request

//make sure at least 1000ms have passed before we perform the callback
delayPromise(p,1000).then((r) => console.log(r));

//also works with reject!
delayPromise(Promise.reject(1),1000).catch((r) => console.log(r));
