Using lodash-webpack-plugin breaks redux-persist functionality

[creage]

I'm not sure if it is lodash's issue (probably not), but adding
new LodashModuleReplacementPlugin
to webpack plugins, causes redux-persist stopping write it's data to localStorage.

Hi @creage!

This plugin rewrites the module paths of lodash to remove feature sets and reduce extraneous functionality to create smaller bundles.

This ended up being a strange issue that I never fully figured out:

lodash-webpack-plugin was somehow converting the forEach important to only handle forEach on arrays. Since we relied on collection iteration this broke things. I have since replaced that usage of forEach with an object.keys -> foreach call, but I am curious if anyone else comes across weird behavior like this.

Hi @rt2zz!

You need to enable the "collections" feature set.

ah, @jdalton as a library author what would be the best way to "enforce" this? i.e. I cannot reasonably expect every consumer to know to set collections: true.

I cannot reasonably expect every consumer to know to set collections: true.

Folks should be consuming the bundled build.
