nodash

Replacement for subset of lodash, with fraction of the size.

Installation

npm i @ebay/nodash

Usage

Simply replace lodash with @ebay/nodash

const get = require('lodash/get');

// becomes

const get = require('@ebay/nodash/get');

Why?

Often, consumers of lodash use just a handful of the methods. Lodash makes this convenient by only requiring what you need:

const get = require('lodash/get'); // or require('lodash.get') if installed

However, Lodash is optimized as an entire library, which is to say it makes heavy reuse of its own methods. So using get may require baseGet, which requires castPath and toKey, which then requires isKey, stringToPath, and isSymbol... and so forth. It keeps going for many more levels.

This ends up with a bundle size of over 7kb just for using get. While that becomes cheaper the more you use Lodash, if all you use is get, it remains quite expensive. The Nodash version of the same method weighs in at ~500b for comparison.

As such, this library is targeted for just those users that need a small subset of Lodash, and not the whole library. It is not intended to be a replacement for Lodash.

Methods

Most methods are identical to Lodash. Some methods have partial support, to shed off edge cases for the sake of saving size. The API for all are otherwise identical to Lodash and can be a drop-in replacement in most cases.
