defe

defe()

A simple, 144 bytes, ES5 compatible and standalone implementation of the deprecated Promise.defer() method.

Usage

const defe = require('defe')

function awesomeSomeStuff () {
  const deferred = defe()

  setTimeout(() => deferred.resolve(), 1000)

  return deferred.promise
}

awesomeSomeStuff().then(() => console.log('I will run one second later'))

By default defe() will use the global Promise object, but you can specify another constructor.

const deferred = defe(Bluebird)

deferred.promise
  .map(() => 'Hey!')
  .filter(t => !!t)
  .then(result => console.log(result))
