signal-promise

signal-promise

Simple wait/notify promise with optional max wait time

npm install signal-promise

Usage

const Signal = require('signal-promise')

const input = new Signal()

while (await input.wait()) {
  console.log('someone typed!')
}

process.stdin.on('stdin', function () {
  input.notify()
})

API

s = new Signal()

Make a new signal

await s.wait([maxWaitTime])

Wait for someone to call notify. If you specify maxWaitTime the promise will resolve after maxWaitTime ms if no notify call has happened.

As a convenience the promise resolves to true so it's easy to use it as a condition.

s.notify([error])

Notify everyone waiting. If you pass an error the wait promise will reject with that error.
