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