README

proxied-promise-object

Proxy all calls to an objects functions to a wrapper which returns promises. In addition to wrapping functions this project will also setup a getter/setter "proxy" so you can treat the proxied objects very similar to their originals (i.e. setting a property on either will effect both).

NOTE: This does not use "real" proxies (ES6)

Works in node & the browser through component

Usage

var proxy = require('proxied-promise-object');

var fs = proxy(require('fs'), PromiseLibary);

fs.stat('xfoo/...').then(
  function() {
  }
);

Proxies are stamped as well to protect wrapping proxies with proxies

var fs = proxy(YourFavPromiseLib, require('fs'));
var fs2 = proxy(YourFavPromiseLib, fs);

// fs === fs2

If there is a global promise object (like in the browser):

var proxied = proxy(callbackReturningObj);

By default when you proxy an object it will "deeply" traverse the object creating proxies even on nested levels.

var proxyObj = proxy(...);

proxyObj.nested.api.call().then(...)

This can be disabled by passing deep: false:

proxyObj = proxy(object, Promise, { deep: false });
