Cloud-based collaborative 2D site planning web app being developed for use by the sponsors of the upcoming San Fernando Valley Mini Maker Faire on Oct 7th, 2017. The minimalistic UI allows users to manipulate, relate and annotate tiles intended to represent tents, booths, port-a-poties and the like.
The client-server architecture knit together with socket.io networking insures real-time synchronization both among different users, and between the users and the MongoDB database backend. Both client and server are implemented in Javascript. The UI is implemented in Raphaël.js, although I am considering switching over to something more modern like snap.js.
While the code is very pre-release at the moment, it is publicly available under the lGPLv3, so if you are so inclined, have a go. Feel free to contact me if you have questions or suggestions. I am the sole developer at the moment, but I'm not at all set on keeping it that way.
