@bitty/get

A really small library, almost 150 bytes minified and gzipped, that gets a value from object using a path expression, and returns received placeholder when value is undefinedss or unreachable.

It's approach is based on idx, from Facebook, and a insight from Vue.js meetup where @IgorHalfeld shows a way to access a property using eval. Yeah, eval!

Install

This module is published under NPM registry, so you can install from any package manager.

npm install --save @bitty/get

# If you're using Yarn use the command below.
yarn add @bitty/get

Usage

Just import get function and gets a value from object using a path expression.

import get from '@bitty/get';

// ...

const name = get(response, 'data.user.name', 'Unknown');

You can use brackets, even on first property.

const title = get(paragraphs, '["data"].children[0].textContent');

Also, expressions could be attached to path.

const id = get(response, 'data.keys[0].number.toString(16)');
