Package Exports

xcase

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 (xcase) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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/encharm/xcase/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
