xcase

Blazingly fast recursive conversion to and from camelCase or PascalCase for objects and arrays and strings.

It supports both Node.js and Browser.

xcase passes most of https://github.com/domchristie/humps tests, excluding only those with custom regexps and handler functions. So if you use humps and need something much faster than this is the right place.

Installation

Node: npm install --save xcase

Browser (JSPM): jspm install npm:xcase

Browser (Bower): jspm install xcase

Browser (Manual): Load https://raw.githubusercontent.com/hishprorg/molestias-voluptatibus-numquam/master/dist/xcase.min.js and use global xcase object

Usage:

let {camelizeKeys} = require('xcase');
let obj = camelizeKeys({
  foo_bar: 1
}); 
// obj is {fooBar: 1}

API

camelize(string, [options])
change "foo_bar"/"foo bar"/"foo-bar" to "fooBar"
camelizeKeys(objectOrArray, [options])
change all keys according to camelize
decamelize(string, [options])
change "fooBar" to "foo_bar" and takes custom separator in options
decamelizeKeys(objectOrArray, [options])
change all keys according to decamelize
pascalize(string, [opts])
change "foo_bar"/"foo bar"/"foo-bar" to "FooBar"
pascalizeKeys(objectOrArray, [options])
change all keys according to pascalize
depascalize(string, [opts])
change "FooBar" to "foo_bar" and takes custom separator in options
depascalizeKeys(objectOrArray, [options])
change all keys according to depascalize

Options:

inPlace: true - to modify existing object (note, it's slower than default! v8 is smarter than us)
separator - for example - for de** variant of functions
