lodash-es and lodash/fp

[mvanlonden]

Hi! It seems like the fp variety of lodash isn't supported in the lodash-es package. Is this intentional?

I'm using CRA and would like to reduce my bundle size through tree shaking. I've read through this thread facebook/create-react-app#1069 and it seems like the CRA's lodash babel plugin implementation is waiting for lodash v5. Is there still a way to benefit from tree shaking using lodash/fp and something like lodash-es?

Hi @mvanlonden!

Tree-shaking is a bit of a lie. Tooling tends to be overly sensitive to potential side-effects, of which Lodash has none. I recommend using babel-plugin-lodash (it works for lodash/fp too) and if you're feeling adventurous combo it with lodash-webpack-plugin with the "currying" feature set enabled.

Update:

Webpack 4 will support the sideEffects field which will allow for better tree-shaking support.
