Ember-deep-set NPM

ember-deep-set

ember-deep-set is a simple utility function to deeply set a value on an Ember Object or POJO. Note that this mutates the object.

To install:

ember install ember-deep-set

Why this addon exists

Ember.set will throw an error if you try to set a value on a non-existent object. For example:

Ember.set({}, 'foo.bar.baz', 123); // Property set failed: object in path "foo.bar" could not be found or was destroyed.

With ember-deep-set, you can safely and deeply set values on POJOs as well as Ember.Objects without having to first create the empty intermediate objects.

Usage

import Ember from 'ember';
import deepSet from 'ember-deep-set';

const { get } = Ember;

let company = {};
deepSet(company, 'region.department.director.name', 'Jim Bob');
deepSet(company, 'region.department.name', 'Accounting');
deepSet(company, 'region.name', 'North America');

get(company, 'region.department.name'); // "Accounting"
get(company, 'region.department.director'); // { name: "Jim Bob" }
