Splittable is a command‑line and programmatic JavaScript module bundler that focuses on ultra‑compact output through aggressive tree‑shaking and automatic code‑splitting. It handles ES6 and CommonJS (including NPM) modules, produces separate entry bundles plus a shared base bundle, and provides a System.import polyfill or async‑script loading for runtime delivery—targeted at developers who need smaller, efficiently split bundles without the overhead of larger tools like Webpack.
