Wmr
wmr is a web application development tool and build system that functions as an ES modules bundler, static site generator, and local development server. It provides a complete environment for creating modern web applications, combining a production compiler with a server that supports hot reloading.
The project is distinguished by its integrated approach to background scripts and routing, serving as both a service worker bundler and a tool for filesystem-based routing. It enables the generation of static HTML via prerendering and provides native integration for spawning web workers to handle heavy computations.
The system covers a broad range of build automation capabilities, including on-demand compilation, middleware-based request handling, and a plugin-driven pipeline for extending build logic. It also includes utilities for managing environment variables, mapping import paths, and analyzing bundle size to optimize production assets.
