How to configure Webix-Jet and Webpack with web server Nginx in sub directory on server Ubuntu?

Nginx configuration without port like url: https://webix.com/demos/admin-app/#!/app/dashboard

Webpack must be used for development only, for production you can build a static js file.

If you really need to run both webpack and nginx, you can use nginx in reverse proxy mode, so it will redirect all queries for specific url to webpack server.
