Documentation

Functions are split into two types: core and utilities. Core functions transform strings in customizable ways. Utility functions are built with core functions and transform the strings in concrete ways.

Core Functions

• removeByRegex
• removeNonDigits
• limitToLength
• addStringAtPosition
• addStringAtPositionIfLength

Utility Functions

• toShortUSPostalCode
• toLongUSPostalCode
• toSSN
• toPhone

Core Functions

Remove By Regex

removeByRegex(String)

removes any of the found regex

kleen.removeByRegex('abc123', /\d/g) // returns 'abc'

Remove Non Digits

removeNonDigits(String)

remove all non-digit characters (anything except 0-9)

kleen.removeNonDigits('abc123') // returns '123'

Limit to Length

limitToLength(String, maxLength:Int)

limits the string to the given maxLength

kleen.limitToLength('abc123', 3) // returns 'abc'
kleen.limitToLength('ab', 3) // returns 'ab'

Add String at Position

addStringAtPosition(String, stringToAdd:String, position:Int)

adds the given string at the position

if the original string length is not as long as the position, does nothing

kleen.addStringAtPosition('123456789', '-', 5) // returns '12345-6789'
kleen.addStringAtPosition('12345', '-', 5) // returns '12345-'
kleen.addStringAtPosition('123', '-', 5) // returns '123'

Add String at Position If Length

addStringAtPositionIfLength(String, stringToAdd:String, position:Int, length:Int)

adds the given string at the position if the original string is of the given length

if the original string length is not as long as the given length, does nothing

if the original string length is not as long as the position, does nothing

kleen.addStringAtPositionIfLength('123456789', '-', 5) // returns '12345-6789'
kleen.addStringAtPositionIfLength('12345', '-', 5, 6) // returns '12345'
kleen.addStringAtPositionIfLength('123', '-', 5, 6) // returns '123'

Utility Functions

Development

PR's Welcome!

Please update code, tests, README, and bump the version number. I'll handle yarn build'ing and npm publish'ing after the PR is in.

yarn test --watch to run jest tests (and watch for future changes to those tests)
