babel-plugin-lodash

The goal of this package is to be an alternative/augmentation of lodash-modularize which is designed with slightly different goals.

This plugin is a simple transform to remove unused lodash code, without forcing the user to cherry pick methods manually. This lets you use lodash naturally (aka as documented) without worrying about bundling parts you're not using.

Example

Converts

import lodash from 'lodash';

lodash.map([1, 2, 3], function(x) {
    // ...
});

(roughly) to

import _map from 'lodash/collection/map';

_map([1, 2, 3], function(x) {
    // ...
});

FAQ

Where's my npm module support?

It will be implemented when plugins can support options (babel/babel#1833).

For now use lodash-modularize.

Do import specifiers work (import {x} from 'lodash')

You know it! You can also use both specifiers and direct imports (import _, {y} from 'lodash').

What about lodash-fp?

We've got ya covered (#3).

Limitations

• You must be using ES6 imports to load lodash.

• Chaining syntax is not supported
