webpack‑tool is a Node / Koa utility that wraps Webpack to provide an easy‑to‑run development server with in‑memory builds, hot‑reloading, proxying and a UI view of build stats, as well as a simple production build command that can also render the UI for the compiled output. It is aimed at front‑end developers who want a quick, configurable setup for developing and debugging Webpack‑based projects without writing a custom Koa/Express server.
