Precompile for production

[SqueezedLight]

Hi guys,
first of all thanks for your great work!
Currently i'm having a hard time precompiling assets for production. As far as i understand, webpack builds the client side code to /app/assets/javascripts/generated where sprockets picks it up. If i run rake assets:precompile on a fresh react_on_rails project the resulting application.js in /public/assets has nearly 2Mb?! What am i missing? Unfortunately i couldn't find documentation that covers this topic.

Any help is greatly appreciated.

Please see:

https://github.com/shakacode/react_on_rails/blob/master/docs%2Fadditional_reading%2Fheroku_deployment.md

and https://github.com/shakacode/react-webpack-rails-tutorial/blob/master/lib%2Ftasks%2Fassets.rake

In terms of the size of the file, I'm not surprised that it's big, depending on what libraries are included.

It should be cached in the browser, and TurboLinks will allow loading it once.

We also plan to use:

• https://github.com/lodash/babel-plugin-lodash
• http://www.2ality.com/2015/12/webpack-tree-shaking.html

Hi, thanks for your quick support. Unfortunately this is not very satisfying as i already removed lodash completely. I will definitely have a look into tree shaking. I think its worth shaving off every kB we can. After posting this issue i found most of my thoughts summed up in this issue - quite helpful: #206
