Node.js Whiteboard App for Team / Educational Collaboration [closed]

Question

I'm looking to build/adapt a shared whiteboard app for team and educational collaboration. Draw on a board, write some text, save picture, clear board, etc. We've already got a simple chat system setup with node.js and socket.io so probably want to stay on that route.

1. What open source apps exist that might be pluggable / adaptable for this use?
2. What node.js / javascript / html5 technologies might be useful for this task?

Answer 1

As far as node.js technologies you would need the following

• express to handle your http server
• socket.io to handle communication

As far as rendering on the client I would recommend

• rapheal as an SVG rendering

Apart from that you need some kind of database, Redis, mongoDB & CouchDB are popular.

Apart from that just write it. Any other libraries you think you might need along the way can be found on the npm registry

However I can offer some package.json examples for my chat and my blog to give some inspiration as to what libraries are useful

I've used express and socket.io. Raphael looks cool. Love to see an example to work from for drawing stuff with node.js – Rahman

I wrote a prototype somewhere. A couple of hours of hacking should do. A quick google search for "node.js whiteboard" should get you started. – Hypophysis
