shorter-js

A small ES6/ES7 library with various JavaScript tools useful for creating light libraries. Featured in KUTE.js, BSN, Navbar.js 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, that is mainly for build consistency testing.

npm

npm install shorter-js

ES6/ES7 Base usage

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

// use the tool in your ES6/ES7 sources
if (supportTransform) {
  doSomeAction()
}

boolean

• isMobile - checks and preserves the client browser is a on Mobile device
• support3DTransform - checks and preserves the client browser capability for webKit perspective
• supportTouch - checks and preserves the client browser capability for touch events
• supportPassive - checks and preserves the client browser capability for passive event option
• supportTransform - checks and preserves the client browser capability for webKit transform
• supportAnimation - checks and preserves the client browser capability for webKit keyframe animation
• supportTransition - checks and preserves the client browser capability for webKit transition

// EXAMPLES
import {support3DTransform} from 'shorter-js'

// filter myAction to supported browsers
if (support3DTransform) {
  myAction()
}

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

• 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

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

// attach a passive mousedown eventHandler
on(targetElement,'click',eventHandler,passiveHandler)
// detach a passive mouseup eventHandler
off(targetElement,'mouseup',eventHandler,passiveHandler)
// attach a single instance passive touchstart eventHandler
one(targetElement,'touchstart',eventHandler,passiveHandler)

misc

• emulateAnimationEnd - utility to execute a callback function when animationend event is triggered, or execute the callback right after for legacy browsers
• emulateTransitionEnd - utility to execute a callback function when transitionend event is triggered, or execute the callback right after for legacy browsers
• getElementTransitionDuration - returns the transitionDuration property of a transition property
• isElementInScrollRange - a quick utility that checks if a target Element surface is scrolled within the visible area of the window
• isElementInViewport - a quick utility that checks if a target Element is scrolled fully into visible window area, might not be useful for elements larger in size than the window itself, the above might be more useful
• passiveHandler - a constant that preserves a standard handler options with passive: true event option used
• queryElement - a simple utility to check if a certain item is an Element or a selector string, and if a selector string find the FIRST Element and return it
• tryWrapper - a simple try() and catch() wrapper for functions, with option to preffix the error logs, poiting out the source of the errors

// EXAMPLES
import {queryElement,emulateTransitionEnd} from 'shorter-js'

// get some target
let targetElement = queryElement('.mySelectorClass');

// emulateTransitionEnd for the above
emulateTransitionEnd(targetElement,callback)

// check if element is in scroll range
// emulateTransitionEnd for the above
if (isElementInScrollRange(targetElement)){
  doSomeAction()
}

strings

• mouseSwipeEvents - preserves the pointer events from mouse actions: start: mousedown, end: mouseup, move: mousemove, cancel: mouseout
• mouseClickEvents - preserves the pointer events from mouse actions: down: mousedown, up: mouseup
• mouseHoverEvents - preserve browser specific mouse hover events: mouseenter and mouseleave OR mouseover and mouseout
• touchEvents - preserves the pointer events from touch actions: start: touchstart, end: touchend, move: touchmove, cancel: touchcancel
• animationDuration - preserves the animationDuration property name supported by the client browser
• animationEndEvent - preserves the animationEndEvent event name supported by the client browser
• transitionDuration - preserves the transitionDuration property name supported by the client browser
• transitionEndEvent - preserves the transitionend event name supported by the client browser

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

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

Advanced Use

To avoid adding un-necessary shorties into your code, you might want to import them directly from their location

// Example
import on from 'shorter-js/src/event/on.js'
import addClass from 'shorter-js/src/class/addClass.js'
