chainProxy

A module help you make calling chain.

I like bluebird but I hate some method like .get and .call, it's ugly!

And some time I want safely get some property in an object.

So I write this module make sync calling to be easy like spark language.

Note

This module only can run in Node 6.x because it use Proxy

Usage

You can use it like:

var _ = require('chainproxy')();
 
Promise.resolve({a: 12333})
  .then(_.a.toString().split('')[0].toString().replace('1', 'replaceStr').length)
  .then(console.log.bind(null, 'result:'), console.error.bind(null, 'catch error:'));

You can set a default value to require('chainproxy')(); param.

If sync calling have throw some error like TypeError, the expression will return the default value; if not set default value, expression will throw the error.

This expression actually create function like that:

function (args, _, defaultValue){
  try{
    _.a.toString().split(args[0])[args[1]].toString().replace(args[2], args[3]).length
  }catch(err){
    if(defaultValue) return defaultValue;
    else throw err;
  }
}

So you can see it's vary quick and easy to use.
