Then apply this CSS classes to a container element.

<div id="container" class="ft ft-light"></div>

Simple time count

This example just counts seconds from start.

import { FancyTimer } from 'fancy-timer';
 
const container = document.getElementById('container');
const ft = new FancyTimer(container, { value: 0, direction: 1 });

Countdown timer with warning

This example setup the countdown timer for 5 minutes (300 seconds). When one minute left it enables warning mode. On finish it calls a callback function.

import { FancyTimer, IFancyTimerOptions } from 'fancy-timer';
 
const container = document.getElementById('container');
const options: IFancyTimerOptions {
  value: 300,
  direction: -1,
  warn: {
    secondsLeft: 60
  },
  onWarning() {
    console.log('Warning!');
  },
  onFinish() {
    console.log('Finish!');
  }
};
const ft = new FancyTimer(container, { value: 300, direction: -1 });

FancyTimer.start(direction?: 1 | 0 | -1)

Start the timer in specified direction: 1 - forward, -1 - backward. If direction is 0 or omitted, using current direction property value.

FancyTimer.stop()

Stop the timer.

FancyTimer.update(value: number, force = false)

Update displaying time. value is in seconds. If force = true it means the timer updates immetiately without animation. This method is not updating any option, so after call start method the timer will display an actual value property.

FancyTimer.updateOptions(options: IFancyTimerOptions)

This method allows to update all options except captions and showDays. If some options are not specified they will be set as undefined (except value, captions, showDays).

FancyTimer.setValue(value?: number | Date | string)

This method is very handy if need to update only value property.
