Jetpack can be used instead of webpack, webpack-cli, webpack-dev-server and webpack-dev-middleware without writing any configuration. Jetpack is a thin wrapper around webpack, and can be extended with any of the webpack configuration.
Taking the configuration out of webpack seems like a recipe for success.
This project is an exploration of some ideas accumulated over a few years using webpack in a variety of projects. Webpack is a very powerful and flexible tool. It applies to a lot of use cases and that is one of the reasons it has so many configuration options. Webpack also evolved over the years but preserved backwards compatibility as much as possible to support the large ecosystem built around it.
I’d be surprised if some of the good ideas in Jetpack don’t find their way in to webpack proper.
