utils-and-helpers -

A simple zero-dependency package full of utilities and helpers you're using across all of your projects. This package is not meant to replace more specialized implementations - you'll find Observable inside but not the mighty rxjs. Rather, this package is alternative to copying and pasting the same code snippets across several projects.

Getting Started

There are four top level namespaces Enums, Helpers, Structures, and Utils. See below for details

Enums

• currency
  • Currency
• http
  • HttpStatus
  • HttpMethod
  • HttpHeader
• primitive
  • Primitive
  • Typeof
  • Operator
  • KeyCode

Helpers

In the Helpers namespace you'll find common one-liners and validations. All helpers are exported from the index file. See below for an orginized view of available helpers.

• array
  • isIn
  • isNotIn
  • arrayNotEmpty
  • arrayMinSize
  • arrayMaxSize
  • zip
  • binaryInsert
  • binarySearch
• boolean
  • isBoolean
• common
  • isDefined
  • equals
  • notEquals
  • isEmpty
  • isNotEmpty
  • length
  • minLength
  • maxLength
• date
  • future
  • isDate
  • before
  • after
• function
  • isFunction
  • compose
  • pipe
  • curry
• number
  • isNumber
  • isDivisibleBy
  • isPositive
  • isNegative
  • gte
  • gt
  • lte
  • lt
• object
  • isObject
  • isNotEmptyObject
  • prop
• string
  • snakeToCamel
  • camelToSnake
  • generateId
  • isString
  • isDateString
  • isAlpha
  • isAlphanumeric
  • isEmail
  • isLowerCase
  • isUpperCase
  • levenshteinDistance
• math
  • normalize
  • rouletteWheel
  • randomBetween

Structures

In the Structures namespace you'll find common data structures that aren't available in the standard library. The data structures here are classes whereas Utils exports interfaces. All data structures are exported from the index file. See below for an orginized view.

• Queue
• LinkedList

Utils

The Utils namespace constains simple interfaces such as Box and functions that act on those interfaces. These functions are not instance methods.

• box
  • Box (interface)
  • adjacent
  • union
  • intersects
  • contains
  • canFit
  • copy
• color
  • RGB (interface)
  • CYMK (interface)
  • COLOR_DASE (equals 16)
  • COLOR_DEPTH (equals 255)
  • mix
  • rgbToHex
  • channelToHex
  • rgbToCmyk
  • cmykToRgb
  • hexToRgb
  • randomHexColor
  • replaceShorthandHex
• cookies
  • Cookie (interface)
  • parseCookies
  • serializeCookie
• lens
  • Lens (interface)
  • composeLens
• middleware
  • NextFunction (type)
  • Stack (type)
  • Middleware (type)
  • Use (type)
  • middleware
• observable
  • Observer (interface)
  • TearDown (type)
  • Observervable (type)
  • interval
