shorter-js v0.3.4

shorter-js

A small ES6+ library with various JavaScript tools, all ESLint valid and with TypeScript definitions, everything useful for creating light libraries or web components. If there is anything that is consistently repeating itself, shorter-js can help you save up to 50% of the code required, with little to no performance cost.

shorter-js is featured in KUTE.js, BSN, Navbar.js and other libraries.

• The purpose of 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. You can make use of "tree shaking" to import one or anything your code needs.
• On that note, all shorties are organized in folders inside the src root folder, the structure is key to understanding the purpose of each type of shortie, whether we have boolean for various basic browser detection or browser feature support, attr for all things Element attributes or strings for most common and most used Element.prototype methods.

npm

npm install shorter-js

ES6+ Base usage

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

// use the tool in your ES6/ES7 sources
if (supportTransform) {
  // have modern browsers do something about that
}

attr

• getAttribute - returns the value of a specified Element attribute;
• getAttributeNS - returns the value of a specified namespaced Element attribute (eg: namespaced SVG attributes);
• hasAttribute - check if element has a specified attribute;
• hasAttributeNS - check if element has a specified namespaced attribute;
• removeAttribute - removes a specified attribute from an element;
• removeAttributeNS - removes a specified namespaced attribute from an element;
• setAttribute - set a new attribute value for a given element;
• setAttributeNS - set a new namespaced attribute value for a given element;

// EXAMPLES
import { getAttribute, hasAttribute, setAttribute } from 'shorter-js';

// check target has certain attribute
if (!hasAttribute(myTarget, 'attribute-name')) {
  setAttribute(myTarget, 'attribute-name', 'new-value');
}

// get attribute value
const currentAttrValue = getAttribute(myTarget, 'attribute-name');

blocks

• documentBody - a shortie for document.body;
• documentElement - a shortie for document.documentElement;
• documentHead - a shortie for document.head;

boolean

• isApple - checks and preserves a boolean value for the client browser is either Apple Safari browser or not;
• isFirefox - checks and preserves a boolean value for the client browser is either Firefox or not;
• isMobile - checks and preserves a boolean value for the client browser is either a Mobile device or not;
• support3DTransform - checks and preserves a boolean value for the client browser capability for webKit perspective;
• supportTouch - checks and preserves a boolean value for the client browser capability for touch events;
• supportPassive - checks and preserves a boolean value for the client browser capability for passive event option;
• supportTransform - checks and preserves a boolean value for the client browser capability for webKit transform;
• supportAnimation - checks and preserves a boolean value for the client browser capability for webKit keyframe animation;
• supportTransition - checks and preserves a boolean value for the client browser capability for webKit transition;

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

// filter myAction to supported browsers
if (support3DTransform) {
  // do something with modern browsers
}

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')) {
  // do something about that
}

event

• on - attach an event listener to a specific target Element;
• off - detach an event listener from a specific target Element;
• one - attach an event listener 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);

For a more advanced method to handle event listeners, I recommend using the event-listener.js.

There are lots more string constants available which include native event names, browser strings, keyboard key codes or ARIA specific attribute names. Be sure to check the src/strings folder for a complete list.

// 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

Here's a simple example to showcase the benefit of using shorter-js.

// This is your typical day to day scripting
const target = document.getElementById('my-element');

target.addEventListener('click', function(e) {
  target.classList.add('my-className');
})

Now make it all shorter. You might want to import shorties directly from their location, something we like to call "tree shaking".

// Example
import on from 'shorter-js/src/event/on';
import addClass from 'shorter-js/src/class/addClass';
import getElementById from 'shorter-js/src/selectors/getElementById';
import mouseclickEvent from 'shorter-js/src/strings/mouseclickEvent';

const target = getElementById('my-element');

on(target, mouseclickEvent, function(e) {
  addClass(target, 'my-className')
})
