babel-plugin-lodash

[c0debreaker]

I'm having a hard time digging through the closed issues looking for solutions on how to use this plugin. Can it be used with create-react-app without ejecting our app?

Thanks!

Unfortunately, no. It cannot be used without ejecting.
We will reconsider this feature if lodash drops chain from the API.

You can, however, use the method described here to reduce your bundle size.

Thanks a lot!

No problem!

It didn't work for me. The bundle size became larger

Using the lodash that came with create-react-app

Then i ran rm -rf build and installed lodash.groupby and lodash.foreach. I used it this way

import _groupBy from 'lodash.groupby';
import _forEach from 'lodash.foreach';

and here are the results

You may be depending on a different version of lodash than you're installing using that unsupported behavior, but I suggest using the slash method not dot.

[c0debreaker]

Ok, I'll try it.

Like I said, "Using the lodash that came with create-react-app" is not a supported behavior and properly importing lodash is probably grabbing a newer, larger version of the library.

Sorry, but I don't think you can tune this much more without ejecting. 😬 Though I don't think babel-plugin-lodash is going to fix this problem.
Let me know if you find out more information and we can add it to the readme. 😄

All babel-plugin-lodash does is replace imports like import { groupBy } from 'lodash with imports like import groupBy from 'lodash/groupBy'. It won’t magically make the bundle smaller, and if you already write granular imports, this is as good as it will get.

And yea, you need to npm install --save lodash.

Yup, after doing a lot of trial and error even with Dan's suggestion, the difference wasn't that much. However, guess what I found out? I changed the way I was importing Material-UI and OMG, I brought it down to 154KB. I'm very happy for that :)

Thanks to both you! Oh, I LOVE CREATE-REACT-APP so much! This is the best creation next to loaf of bread. :)
