How to use libraries in webpack modules the right way

Question

Whats best practice for using libs like lodash in modules bundled by webpack?

1. require it to a global variable

window._ = require('lodash');

2. webpack conf

new webpack.ProvidePlugin({ _: 'lodash' });

3. Require it in a module if I want to use lodash in that module like

let _ = require('lodash');

or

import _ from lodash;

4. import only the functions I want to use in the current module from lodash like

import { find, map } from 'lodash';

Answer 1

import { find, map } from 'lodash';
