VILLASweb is a tool to configure real-time co-simulations and display simulation real-time data in the web browser. The term frontend refers to this project, the actual website.
The frontend connects to two backends:
The VILLASweb-backend in turn controls infrastructure components via the VILLAScontroller component
VILLASnode provides actual simulation data via websockets. VILLASweb-backend provides any other data such as user accounts, infrastructure components and configurations, dashboards etc. For more information on the backends see their repositories.
