get-value

Use property paths (a.b.c) to get a nested value from an object.

Benchmarks

This is 10x faster and more performant than dot-prop, and it passes all of the dot-prop tests.

Of the libs benchmarked, dot-prop was the least performant:

#1: deep
  get-value x 3,308,335 ops/sec ±1.32% (94 runs sampled)
  dot-prop x 197,631 ops/sec ±1.27% (94 runs sampled)
  getobject x 218,635 ops/sec ±1.51% (91 runs sampled)

#2: shallow
  get-value x 5,762,976 ops/sec ±1.21% (95 runs sampled)
  dot-prop x 695,892 ops/sec ±1.42% (95 runs sampled)
  getobject x 724,493 ops/sec ±1.46% (93 runs sampled)

Also, get-value supports escaping dots in paths, which is common when object keys are file paths with extensions, dot-prop does not.

Install

Install with npm

$ npm i get-value --save

Install with bower

$ bower install get-value --save

Usage

var get = require('get-value');

var obj = {a: {b : {c: {d: 'foo'}}}, e: [{f: 'g'}]};
get(obj, 'a.b.c');
//=> {d: 'foo'}

get(obj, 'a.b.c.d');
//=> 'foo'

get(obj, 'e[0].f');
//=> 'g'

key as an array

Optionally pass the key as an array (this is useful when you need to dynamically build up the property name)

var obj = {a: {b: 'c'}};
get(obj, ['a', 'b']);
//=> 'c'
