delay 
Delay a promise a specified amount of time
Install
$ npm install --save delay
Usage
const delay = require('delay');
delay(200)
.then(() => {
// executed after 200 milliseconds
});
somePromise()
.then(delay(100))
.then(result => {
// executed 100 milliseconds after somePromise resolves
// the result from somePromise is passed through
});
// and with Babel and async functions
async () => {
bar();
await delay(100);
// executed 100 milliseconds later
baz();
}();
// there's also delay.reject() that takes the value, and rejects it `ms` later
Promise.resolve('foo')
.then(delay.reject(100))
.then(x => blah()) // never executed
.catch(err => {
// executed 100 milliseconds later
// err === 'foo'
});
// you can also specify the rejection value
Promise.resolve('foo')
.then(delay.reject(100, 'bar'))
.then(x => blah()) // never executed
.catch(err => {
// executed 100 milliseconds later
// err === 'bar'
