shorter-js

A small ES6/ES7 library with various JavaScript tools useful for creating light libraries. Featured in KUTE.js, BSN and other libraries.

The purpose if the library is to speed up the development workflow, minimize the size of larger libraries by providing a shorter syntax for most used JavaScript API methods, most used strings or other helpful utilities.

While the library comes with a working build in the dist folder, the main purpose of the library is mainly to be used in other libraries.

npm

npm install shorter-js

ES6/ES7 Base usage

// import the tool you need
import {on} from 'shorter-js'

// use the tool in your ES6/ES7 sources
on(elementTarget,eventName,eventHandler,options)

Class

• addClass - add a class to a target Element
• removeClass - remove a class from a target Element
• hasClass - checks the existence of a class for a target Element

// EXAMPLES
import {addClass,removeClass,hasClass} from 'shorter-js'

// add a class
addClass(targetElement,'className')
// remove a class
removeClass(targetElement,'className')
// check for a class
if (hasClass(targetElement,'className')) {
  myAction()
}

Event

• mouseEvents - preserves the pointer events from mouse actions: down: mousedown, up: mouseup
• touchEvents - preserves the pointer events from touch actions: start: touchstart, end: touchend, move: touchmove, cancel: touchcancel
• mouseHover - preserve browser specific mouse hover events: mouseenter and mouseleave OR mouseover and mouseout
• on - attach an event handler to a specific target Element
• off - detach an event handler from a specific target Element
• one - attach an event handler to a specific target Element, and detach when complete
• supportPassive - a constant that checks and preserves the client browser for passive event capability
• passiveHandler - a constant that preserves a standard handler options with passive: true event option used

// EXAMPLES
import {on,off,one,mouseEvents,touchEvents,passiveHandler} from 'shorter-js'

// attach a passive mousedown eventHandler
on(targetElement,mouseEvents.down,eventHandler,passiveHandler)
// detach a passive mousedown eventHandler
off(targetElement,mouseEvents.down,eventHandler,passiveHandler)
// attach a single instance passive mousedown eventHandler
one(targetElement,touchEvents.start,eventHandler,passiveHandler)

Transition

• supportTransform - checks and preserves the client browser capability for webKit transform
• supportTransitions - checks and preserves the client browser capability for webKit transition
• transitionEndEvent - preserves the transitionend event name supported by the client browser
• transitionDuration - preserves the transitionDuration event property supported by the client browser
• getElementTransitionDuration - returns the transitionDuration property of a transition property
• emulateTransitionEnd - utility to execute a callback function when transitionend event is triggered

// EXAMPLES
import {on,supportTransitions,transitionEndEvent,emulateTransitionEnd} from 'shorter-js'

// check if client supports transitions
if (supportTransitions){
  // attach transitionend handler
  on(targetElement,transitionEndEvent,eventHandler,options)
} else {
  eventHandler()
}

// the above should be equivalent to a much shorter
emulateTransitionEnd(targetElement,eventHandler)
