clocktick

Clock-accurate timeout for Node.js and browser. Basically it is identical to setTimeout, but it triggers callback function precisely on the next second.

example

See an example here

accuracy

Accuracy should be around 1–2ms.

installation

npm install clocktick

usage

Usage is similar to setTimeout, but without delay parameter:

var tick = require('clocktick')
tick(callback) // Ticks every second

You can use the delay parameter, but it is in seconds:

tick(callback, 2) // Ticks on 2nd second (00, 02, 04, 06, 08, 10,...)

You can also offset seconds:

tick(callback, 3) // Ticks on 3rd second (03, 06, 9, 12, 15, 18, ...)
tick(callback, 3, 1) // Ticks on 3rd+1 second (04, 07, 10, 13, 16, 19, ...)
tick(callback, 3, 2) // Ticks on 3rd+2 second (05, 08, 11, 14, 17, 20, ...)

repeat

You can repeat the tick by just calling it again:

tick(callback)

function callback () {
  console.log('tick')
  tick(callback)
}

cancel

You can cancel the tick by using clearTimeout:

var timeout = tick(callback)

clearTimeout(timeout)

testing

Clone to desktop and then run following commands at clocktick folder:

npm install
npm test

building

npm install
npm run build
