How to prepare .js files from webpack for production?

Question

webpack

Greetings. Due to the fact that at the moment 'bower is maintained', I decided to try webpack, but I probably ran into a misunderstanding of this tool.
Let's take, for example, a standard one-page html/css/javascript website template. With the help of webpack in the development stage, this is all assembled into one 'bundle.js', for production we take out the css in our file, and js should remain in 'bundle.js', along with the webpack header, which will be included in 'index. html' via script? Or is there still a plugin / way to pull pure js from the bundle?
PS Previously, I collected this with gulp, in build.js there was only my code, without "garbage".

For production, it should be minified, all these headers there will be indistinguishable from regular code.
Pulling out pure JS does not make sense, you will lose one of the main advantages of Webpack - modularity.
