get-value

What is get-value?

The get-value npm package is used for safely retrieving nested values from an object or array. It is useful when dealing with deeply nested structures where checking for the existence of each level can be cumbersome. It allows for specifying paths to the desired value using a string or an array of keys/indices.

What are get-value's main functionalities?

Get nested values

Retrieve a nested value from an object using a string path.

const get = require('get-value');
const obj = { a: { b: { c: 'd' } } };
console.log(get(obj, 'a.b.c')); // 'd'

Use array paths

Retrieve a nested value using an array of keys as the path.

const get = require('get-value');
const obj = { a: { b: { c: 'd' } } };
console.log(get(obj, ['a', 'b', 'c'])); // 'd'

Specify default values

Provide a default value to return if the full path does not exist.

const get = require('get-value');
const obj = { a: { b: { c: 'd' } } };
console.log(get(obj, 'a.b.e', { default: 'default value' })); // 'default value'

Split string paths

Retrieve values from keys that include a dot or other special characters by specifying a custom separator.

const get = require('get-value');
const obj = { 'a.b': { c: 'd' } };
console.log(get(obj, 'a\.b.c', { separator: '\.' })); // 'd'

Other packages similar to get-value

lodash.get

lodash.get is a method from the Lodash library that provides similar functionality to get-value. It allows for retrieving nested values with a default option. Lodash is a larger utility library, so lodash.get is part of a broader suite of tools.

dot-prop

dot-prop is another package that allows for getting and setting nested properties. Unlike get-value, dot-prop also supports setting values. It uses a dot notation string as the path.

deep-get-set

deep-get-set is a package that not only gets but also sets deep values. It is less popular than get-value and does not have as many configuration options.
