caseless-proxy

caseless-proxy

Create ES6 proxy object with case-insensitive properties.

This library has similar semantics to the caseless library but is implemented as a proxy object. This way native javascript constructs can be used to get/set/delete properties in a case insensitive manner.

Objects created with this library behave exactly like normal javascript objects with the exception that property access happens in a case insensitive way.

Usage

caseless:

var headers = {};
var c = caseless(headers);
c.set('a-Header', 'asdf');
c.get('a-header') === 'asdf';

caseless-proxy:

var headers = {};
var c = caselessProxy(headers);
c['a-Header'] = 'asdf';
c['a-header'] === 'asdf';

caseless:

c.has('a-header') === 'a-Header'

caseless-proxy:

'a-header' in c

caseless:

var headers = {};
var c = caseless(headers);
c.set('a-Header', 'fdas');
c.swap('a-HEADER');
c.has('a-header') === 'a-HEADER';
headers === {'a-HEADER': 'fdas'};

caseless-proxy:

var headers = {};
var c = caselessProxy(headers);
c['a-Header'] = 'asdf';
function swap (caseless, property) {
  let tmp = caseless[property];
  delete caseless[property];
  caseless[property] = tmp;
}
swap(c, 'a-HEADER');
headers === {'a-HEADER': 'fdas'};

API

caselessProxy( [Object target] );

Creates a proxy to the target object with case insensitive property access. Will create a new object when target is omitted.
