domture allows you to load packages and scripts directly on a jsdom instance for testing purpose.
You can load npm packages as well as local files (by default relative to current working directory .).
domture supports two loaders: systemjs and webpack.
When using systemjs, it leveages systemjs magic to load any type of module files.
However, certain NodeJS resolution does not work currently, and also code coverage is not available.
When using webpack, it bundles the files you try to import with webpack and load them into jsdom through script tags.
The NodeJS resolution is complete and code coverage is (will be) available.
However, additional bundle time is needed and bundles management still need to be planned out and implemented in the future.
You also lost the magic from systemjs.
By default, webpack will be used as the default loader.
