cancelp

a cancelable promise

usage

import cancelp from 'cancelp'

const promise = cancelp((resolve, reject) => {
  setTimeout(
    () => resolve('Hello'),
    100
  )
})

promise.catch(e => {
  console.log(e)
  // => 'hello, you are stopped now'
})

promise.then(() => {
  // this never runs
})

promise.cancel('Hello, you are stopped now')

Instead of calling cancel you can also call cancelReject or cancelResolve. These act like you would expect, resolving/rejecting the values you pass to them immediately
