Package devserver makes it easy to view statically generated websites and automatically rebuild them when source data changes. When combined with the "livejs" plugin, it is possible to have a live preview of your site.
DevServe should be called to start a web server using the provided builder. While the source directory will be watched for changes by default, it is possible to pass in additional directories to watch; modification of these directories will automatically trigger a site rebuild. This function does not return and will continue watching for file changes and serving your website until it is terminated.
