JSPM – x-utils-es@1.1.1

Package Exports

x-utils-es

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (x-utils-es) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Simple javascript, lodash alternative library, to help with type validation, includes no external plugins.

esmodule supports esnext, es2015 and umd
Lightweight, minified

Install

$/ npm i x-utils-es

Why use it ?

Validate data
Good naming conventions
Similar to lodash
No dependencies
UMD/esm support so you can use in most environments: (AMD, Node, or browser)

Version support

import {} from 'x-utils-es' // (defaults to esm)
import {} from 'x-utils-es/umd' // for browser and commonjs support
const {} require('x-utils-es/umd') // with node

// browser
<script src="..path/x-dispatcher/umd">
   const {...} = window.exutils // get access to all utils
</script>

Documentation

METHODS	RETURN	DESCRIPTION
objectSize({})	`Number`	Checks provided item is an object with properties
last([])	`last index`	provide array and return last index
isFunction(data)	`boolean`	check if a function
copyBy(data{},refs[])	`Object copy`	provide data{} with array[] of property references to match
timer(cb=>,time=0)	`-`	you can replace setTimeOut with this method, same principal applies, additionally timer is cleared after callback
interval(cb=>,every=0, endTime=0)	`-`	just like setTinterval, will call `every` time, and clear interval on `endTime`
validID(id)	`string`	return string without space to lowerCase
isNumber(num=null)	`boolean`	check if provided num is type of number
isPromise(defer)	`boolean`	check if provided data is a Promise
uniq(arr)	`array`	provide array[2,2,3,3,'b','b'], and returns uniq array: [2,3,'b']
isObject(data)	`boolean`	check if provided data is true Object.prototype not Array.prototype
isArray(data)	`boolean`	check if provided data is true Array.prototype
isString(data)	`boolean`	check if provided data is string
isFalsy(data)	`boolean`	check if any data provided is: '', false, null, =<0, undefined, or empty data type
copy(data)	`copy of data`	return copy of data, or return error.toString() if undefined
delay(time=0)	`Promise`	resolve promise by specified time in ms
someKeyMatch( object = {}, source = {})	`boolean`	provide 2 objects and check if any key names match, object and source order placement doesn't matter :)
exectKeyMatch( object = {}, source = {})	`boolean`	provide 2 objects and check if ALL keys names match, object and source order placement doesn't matter :)
head( arr)	`first index`	return first index from up to 2 level array: [[1,2]]
log(,,,)	`-`	console.log, with prefix `[log]`
warn(,,,)	`-`	console.warn, with prefix `[warning]`
onerror(,,,), error(,,,)	`-`	console.error, with prefix `[error]`
