I see there have been a few stabs at getting typescript working well with the Roll20API -- here's another one. <a href="https://github.com/jmhnilbog/Roll20Sandbox" rel="nofollow">https://github.com/jmhnilbog/Roll20Sandbox</a> Goals: Test locally. Debugging in the API console is something I want to avoid. Easy compatibility with the all the other scripts flying around. Intellisense. Never have to hunt down a rogue "rollableTable" when I meant "rollabletable", and never have to look up what the heck keys exist on which kinds of Roll20Objects. To those ends, there's code in here to create a sandbox object with the same interface as the top level scope in the Roll20Api sandbox model, tons of optional logging, and commands to build output files and run mocha/chai tests locally against your code. Now, I haven't actually DONE a crazy amount of work with the API, because the cut/paste/pray development cycle drives me bonkers and I wanted to get this in place before going all-in. I would love some feedback.
