How to deploy node that uses Webpack to heroku

Question

I'm using webpack.

Also I don't commit npm_modules folder and public folder, where all generated files are. And I can't figure out how to build my app (I have webpack build command) after deploy and setup my server (it's already looking for public folder).

It seems me a bad idea to commit before upload. Maybe there are some gentle decisions... Any thoughts?

"heroku-postbuild": "webpack -p --config ./webpack.prod.config.js --progress" 

this is better because if you use postinstall, everytime you do npm i the build script get fired
