p-min-delay

Delay a promise a minimum amount of time

While the delay module delays the promise a specified amount of time and then resolves it, this module ensures the promise resolves after the specified amount of time.

Useful when you have a promise that may settle immediately or may take some time, and you want to ensure it doesn't settle too fast. For example, if you want to show a loading indicator for at least 1 second (but longer if needed) to prevent a confusing flash in the UI.

Install

npm install p-min-delay

Usage

import pMinDelay from 'p-min-delay';

const value = await pMinDelay(somePromise, 1000);
// Executed after minimum 1 second even if `somePromise` fulfills before that
