lib-js-util-promise

The lib includes the utilities depicted below:

• promiseFlat - applies function to iterable and executes returned promises concurrently with optional limit
• promiseSleep - promise version of setTimeout
• promiseTimeout - wraps the promise/async function with a timeout so it doesn't run forever
• resolvePromiseCb - calls the callback or resolves the Promise if no cb
• waitForCondition - wait for sometime until an action resolves to a truthy result

Installing

npm install --save https://github.com/bitfinexcom/lib-js-util-promise.git

Testing

npm run test

Usage

const { promiseSleep, promiseTimeout } = require('@bitfinex/lib-js-util-promise')

const someSlowFunc = async () => {
  await promiseSleep(5000) // wait 5s
  return ['user 1', 'user 2']
}

const main = async () => {
  try {
    await promiseTimeout(someSlowFunc(), 3000) // wait max 3s
  } catch (err) {
    console.error(err) // should reach here
  }
}

main()
