Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@sigmacomputing/babel-plugin-lodash

A simple transform to cherry-pick Lodash modules so you don’t have to.

Combine with lodash-webpack-plugin for even smaller cherry-picked builds!

@sigmacomputing/babel-plugin-lodash is forked from babel-plugin-lodash which has since been abandoned.

Install

NPM

$ npm install --save lodash
$ npm install --save-dev babel-plugin-lodash @babel/cli @babel/preset-env

Yarn

$ yarn add lodash
$ yarn add @sigmacomputing/babel-plugin-lodash @babel/cli @babel/preset-env -D

Example

Transforms

import _ from 'lodash';
import { add } from 'lodash/fp';

const addOne = add(1);
_.map([1, 2, 3], addOne);

roughly to

import _add from 'lodash/fp/add';
import _map from 'lodash/map';

const addOne = _add(1);
_map([1, 2, 3], addOne);

Usage

.babelrc
{
  "plugins": ["@sigmacomputing/babel-plugin-lodash"],
  "presets": [["@babel/env", { "targets": { "node": 6 } }]]
}

Set plugin options using an array of [pluginName, optionsObject].

{
  "plugins": [
    [
      "@sigmacomputing/babel-plugin-lodash",
      { "id": "lodash-compat", "cwd": "some/path" }
    ]
  ],
  "presets": [["@babel/env", { "targets": { "node": 6 } }]]
}

The options.id can be an array of ids.

{
  "plugins": [
    ["@sigmacomputing/babel-plugin-lodash", { "id": ["async", "lodash-bound"] }]
  ],
  "presets": [["@babel/env", { "targets": { "node": 6 } }]]
}
Babel CLI
$ babel --plugins @sigmacomputing/babel-plugin-lodash --presets @babel/es2015 script.js
Babel API
require('babel-core').transform('code', {
  plugins: ['@sigmacomputing/babel-plugin-lodash'],
  presets: [['@babel/env', { targets: { node: 6 } }]],
});
webpack.config.js
'module': {
  'loaders': [{
    'loader': 'babel-loader',
    'test': /\.js$/,
    'exclude': /node_modules/,
    'query': {
      'plugins': ['@sigmacomputing/babel-plugin-lodash'],
      'presets': [['@babel/env', { 'targets': { 'node': 6 } }]]
    }
  }]
}

FAQ

Can this plugin produce ES2015 imports rather than CommonJS imports?

This plugin produces ES2015 imports by default. The @babel/plugin-transform-modules-commonjs plugin, which is included in the @babel/preset-es2015 preset, transforms ES2015 import statements to CommonJS. Omit it from your preset to preserve ES2015 style imports.

Limitations

  • You must use ES2015 imports to load Lodash
  • Babel < 6 & Node.js < 4 aren’t supported
  • Chain sequences aren’t supported. See this blog post for alternatives.
  • Modularized method packages aren’t supported
