Happy DOM is a JavaScript implementation of a web browser
Happy DOM is a JavaScript implementation of a web browser without its graphical user interface. It includes many web standards from WHATWG DOM and HTML. The goal of Happy DOM is to emulate enough of a web browser to be useful for testing, scraping web sites, and server-side rendering. Happy DOM focuses heavily on performance and can be used as an alternative to JSDOM. Happy DOM now supports Declarative Shadow DOM which can be used for server-side rendering of web components. This package makes it possible to use Happy DOM with Jest.
