Get and set nested variables of an object, includes support for Backbone Models

Usage

Complete API Documentation.

Example

// Import
import { setDeep, getDeep } from 'getsetdeep'

// Prepare
const obj = {
    a: {
        b: {
            c: 3,
        },
    },
}

// Get
console.log(getDeep(obj, 'a.b.c')) // 3
console.log(setDeep(obj, 'a.b.c', 4)) // 4
console.log(getDeep(obj, 'a.b.c')) // 4

Notes

  • setDeep also has a fourth argument opts for options, currently we support the options:
    • onlyIfEmpty defaults to false, if specified to true then setDeep will only set the value if the current value is null or undefined
  • We also work with getters get(key) and setters set(attrs, opts), enabling support for Backbone.js models as well as others

Security

To satisfy the egos of some security researchers, just as you wouldn't do obj[prompt('some user input')] = 'value' don't do setDeep(obj, prompt('some user input'), 'value'), obviously. Rather than getsetdeep preventing __proto__ access, we assume the consumers of this library are intelligent enough to do what they intend.
