I would want to build a prototype app similar to like cloud9 ide. What makes it cool is that you can run server side code using it, and I thought that would be quite risky.
How is this possible? Or atleast what's the concept on how c9 able to execute and create server instance
Are there opensource projects that has the same feature using node.js?
they probably use some kind of virtualisation to run server code, that way the code is contained (you might be able to use something like LXC to achieve this).
Cloud9 is actually open source, and runs on node.js
What @Ezequiel said, but also:
There is https://gf3.github.io/sandbox/, which spawns a new node process that executes the code in a restricted environment created with http://nodejs.org/api/vm.html.
Have a look at the source to get an idea:
sandbox.js spawns a new process running shovel.js and sends it code using STDINshovel.js creates a the environment to run the codeThe executing process can run as a user with no rights.
ps. I'm not saying this is totally secure (vm doesn't claim to be that, see vm.runInNewContext)
