Component is not maintained anymore. See here #639 for more information.

You can stil use the component registry on to search for components. All the components are not affected, because most of them also provide a package.json file. The component.json files in these components are still kept to provide backwards compatibility for component and duo.

Think of it as an opinionated npm + browserify + rework-npm + grunt/gulp/broccoli all wrapped into component build.
