Soonish

Sometimes you just need to chill for a second.

Installation

npm install soonish

Usage

soonish(min, max, [callback])

Execute the provided callback after a random delay between min and max milliseconds. If callback is omitted, a function will be returned that can be used in a promise chain to achieve the same effect.

soonish(max, [callback])

Execute the provided callback after a random delay between max * 0.5 and max milliseconds. If callback is omitted, a function will be returned that can be used in a promise chain to achieve the same effect.

Callback Example

#!/usr/bin/env node
const soonish = require('soonish')
const debug = require('debug')('test')

debug('before')
soonish(0, 500, () => {
  debug('after first')
  soonish(500, () => {
    debug('after second')
  })
})

$ DEBUG=test ./example.js
  test before +0ms
  test after first +172ms
  test after second +282ms

Promised Example

#!/usr/bin/env node
const soonish = require('soonish')
const debug = require('debug')('test')

Promise.resolve()
  .then(() => { debug('before') })
  .then(soonish(0, 500))
  .then(() => { debug('after first') })
  .then(soonish(500))
  .then(() => { debug('after second') })

$ DEBUG=test ./example.js
  test before +0ms
  test after first +140ms
  test after second +309ms

Any values received will be passed through to the next promise in the chain:

#!/usr/bin/env node
const soonish = require('soonish')

Promise.resolve('hello, world!')
  .then(soonish(500))
  .then(console.log)

$ ./example.js
hello, world!
