async-sleep

Promise-based sleep that supports resolve and reject with defined results.

Install

npm i --save async-sleep

Usage:

Use sleep function directly:

import sleep from 'async-sleep'; // var sleep = require('async-sleep') also works 
 
const mock = {
  message: 'Hello world'
};
 
sleep(2000, mock).then(console.log); // { message: 'Hello world' }

Use resolve method:

import sleep from 'async-sleep';
 
const mock = {
  message: 'Hello world'
};
 
sleep.resolve(2000, mock).then(console.log); // { message: 'Hello world' }

Use reject method:

import sleep from 'async-sleep';
 
const mock = {
  error: 'Something went wrong...'
};
 
sleep.reject(2000, mock)
  .then(() => console.log('this message will never be shown'))
  .catch(console.log); // { error: 'Something went wrong...' }

Use randomResolve method:

import sleep from 'async-sleep';
 
const mock = {
  message: 'Hello world'
};
 
sleep.randomResolve(100, 1000, mock).then(console.log); // { message: 'Hello world' }

Use randomReject method:

import sleep from 'async-sleep';
 
const mock = {
  error: 'Something went wrong...'
};
 
sleep.randomReject(100, 1000, mock)
  .then(() => console.log('this message will never be shown'))
  .catch(console.log); // { error: 'Something went wrong...' }
