Q-Link

Reduce boiler-plate in Q then calls by creating functions to invoke methods on objects.

e.g.

getNames().then(function (names) {
  return names.join(', ');
});

with q-link can be rewritten as:

join = qLink('join');

getNames().then(join(', '));

The join function returns a function which takes arguments which in turn returns a function which takes an object and applies the join method with the provided arguments.

This is useful with Q as the then and fail methods take functions which operate on the result of the promise

Installation

npm install q-link --save

Usage

Q-link is a single function which takes names of methods and returns functions to apply those methods:

filter = qLink('filter');

The q-linking of multiple methods is more useful in CoffeeScript or ECMAScript 6 where it can be used with destructuring assignment:

[filter, map, join] = qLink 'filter', 'map', 'join'

Non-Q usage

While this module was created to reduce boiler-plate while working with Q, there is nothing Q-specific about it and it may be used anywhere where a function is used to invoke a method on a passed object - for example operating on elements in an array or providing a callback (when the callback takes a single success argument).

split = qLink('split');

fullNames.map(split(' '));
