Dollars

write less, do more, save dollars - This is the utility library for Node.js and often praised the jQuery of Node.js (just kidding, I made that up). It contains all the bat-shit-crazy utilities that I ship and create between different projects.

Installation

This module is only meant for Node.js usage or high-end browsers. It's released in the public npm registry and can be installed using:

npm install --save dollars

Usage

In all examples we assume that the library is required as followed:

'use strict';
 
var dollars = require('dollars');

Or if you require more swag in your application you can require it as following:

var $$$$$$$$$$$$$$$$$$$ = require('dollars');

Table of Contents

Object

The dollars.object contains all object specific utility methods. We do try to provide API parity with the Array methods. The object is also aliased as dollars.obj for shorter notation.

The following methods are available:

dollars.object.clone

Create a shallow clone of the given object. So only the first level properties are copied on to a new clean object.

var obj = dollars.object.clone({ foo: 'bar' });

dollars.object.map

Map the values of the object in to something completely different. It returns a new object with new values. This method requires 2 arguments:

  1. Object Object who's values need to be mapped.
  2. Function Mapping function which is called for every property in the object. The function receives the value as first argument and the key as second argument.
var obj = dollars.object.map({ foo: 'bar' }, function (value, key) {
  return value.toUpperCase();
});
 
// Results in: { foo: 'BAR' }

dollars.object.each

Execute the supplied callback for each key/value in the given object. The method requires 2 arguments:

  1. Object Object who's values need to be mapped.
  2. Function Iteration function which is called for every property in the object. The function receives the value as first argument and the key as second argument.
dollars.object.each({ foo: 'bar', bar: 'foo' }, function each(value, key) {
  console.log(key +':'+ value);
});
 
// Results in: foo:bar, bar:foo

dollars.object.breaks

A breakable iteration variant of dollars.object.each. In order to break out the iteration you need to return false. Just like the each method we accept the following arguments:

  1. Object Object who's values need to be mapped.
  2. Function Iteration function which is called for every property in the object. The function receives the value as first argument and the key as second argument.
dollars.object.breaks({ foo: 'bar', bar: 'foo' }, function (value, key) {
  console.log(key +':'+ value);
  return false;
});
 
// Results in: foo:bar -- As the iteration is broken after the first.

dollars.object.concat

Concatenate multiple objects to one single uber object. All supplied objects will be merged in to the first supplied object. There is no limit to the amount of objects that can be merged in to one.

dollars.object.concat({ foo: 'bar' }, { bar: 'foo' }, { hello: 'world' });A
 
// Results in: { foo: 'bar', bar: 'foo', hello: 'world' }
