library0.3.0jsnpmunverified

A rudimentary error overlay for webpack-serve, mimicking the overlay from webpack-dev-server. Version 0.3.0 is the latest stable release, with no recent updates. The package requires webpack-serve and provides a minimal, quick way to display compilation errors in the browser during development. It uses a WebSocket connection similar to webpack-hot-client and requires no extra configuration. Conditional require with environment check is recommended to avoid inclusion in production builds.
