Just a JS file... What do you want to create?

Previously I was just using HTML5 boilerplate, but I wanna do more, without configuring webpack etc :D

You don't have to use webpack.

rollupjs.org/guide/en

Don't listen to @pugson he's lying.

Look for "javascript cli". There's been an explosion of them lately.

There was one with no config. Forgot what it was called though. Feather?

Use parceljs.org it is basically something like Webpack, BUT without the config! It has most of the things create-react-app offers out of the box, but not restricted to React.

Yeah that's the one I meant.
