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
