longcut

Cut your deep data structures into smaller pieces using regular expressions.

Installation

npm install longcut

Usage

var longcut = require('longcut').longcut;
var lc = longcut({
  key1: [10, 20, 'hello'],
  key2: { another: 'child object' },
  key3: 'just a string'
});

console.log(lc('key1')(2).val());
// hello
console.log(lc('key2')('another').val());
// child object
console.log(lc(/3/).val());
// { key3: 'just a string' }
console.log(lc('key1')(/2/).val());
// [ 20 ]

Description

Longcut lets you slice and dice your data structures with a very terse syntax where you don't have to worry about the exact types involved and with regular expressions at your disposal.

Given

var obj = {
  key1: [10, 20, 'hello'],
  key2: { another: 'child object' },
  key3: 'just a string'
};
var lo = longcut(obj);

JavaScript	longcut	value
obj['key2'][3]	lo('key2')(3).val()	hello
obj['key2']['another']	lo('key')('another').val()	child object
horribly complicated!	lo(/3/).val()	{ key3: 'just a string' }
