Webpacker: Support for minifying / compressing webpacker:compile output
Currently the packs produced by webpacker:compile are unminified, uncompressed files. The normal asset pipeline files get minified and gzip'd. Are there plans to support this functionality for webpacker? Thanks.

They are minified and compressed when compiled in the production environment, unless you changed the default configuration: https://github.com/rails/webpacker/blob/master/lib/install/config/webpack/production.js

NODE_ENV=production bundle exec rails/rake webpacker:compile - that should compile production ready assets

when I try Chrome Audit tool, it says JS can use more minifying.

Can you provide the URL of a sample file? Did you build it with the production config?

Yes, NODE_ENV is set to production in my environment variables.

The file looks minified. I am not sure how Lighthouse calculated the gains you can have. After running your file through uglify 2, I get a 9% reduction, but I guess this is because you are not using the latest Uglify version.
I really think this is a Lighthouse problem here.

On another application, I installed PageSpeed module, and lighthouse got happy and no complains. I will dig into this and report my findings later.
