get-object

Get a property from an object using dot (object path) notation.

Install with npm

$ npm i get-object --save

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

get({a: {b: {c: 'd'}}}, 'a.b.c');
//=> {c: 'd'}

If you want only the value, not key/value, use get-value.

get a value from an object

get({a: 'aaa', b: {c: 'd'}}, 'a');
//=> {a: 'aaa'}

get({a: 'a', b: {c: 'd'}}, 'b.c');
//=> {c: 'd'}

get a value from an array

get(['a', 'b', 'c'], '0');
//=> ['a']

get(['a', 'b', 'c'], 2);
//=> ['c']

get nested value from an array

get({a: ['a', 'b', 'c']}, 'a.0');
//=> ['a']

get({a: ['a', 'b', 'c']}, 'a.2');
//=> ['c']

get({a: {b: ['a', 'b', 'c']}}, 'a.b.2');
//=> ['c']

support array notation

get({a: ['a', 'b', 'c']}, 'a[0]');
//=> ['a']

get({a: ['a', 'b', 'c']}, 'a[2]');
//=> ['c']

get({a: {b: ['a', 'b', {c: 'd'}]}}, 'a.b[2].c');
//=> {c: 'd'}
