How to bundle html, js and css in one html file with webpack?

I use html-webpack-plugin inject the output from Webpack into a index.html file.

Assuming you mean you want to inline all those files into one http request of index.html you can use html-webpack-inline-source-plugin to achieve this.

shameless plug incoming

I found webpack too heavy weight, especially when I'm already using browserify to inline my require()'s. So I wrote a ~30 line npm cli package using JS's string.replace: https://www.npmjs.com/package/inline-scripts. Usage, $ inline-scripts src/index.html out/index.html
