Javascript/NodeJS Scripting of Gazebo (python also?)

This might be good for a FAQ: (at least for beginners here like me):

The tutorials list a number of ways JS/NodeJS programs can pub/sub to Gazebo. But it also hints at more API functions that can be reached: e.g Reading SDF model information:

http://gazebosim.org/tutorials?tut=gazebojs_models&cat=gazebo

What things that can normally only be done via C++ plugins can be also be done with JS?

Same question for Python.

[I certainly realize the performance will not be the same as a in-process library written in C++, but for some use cases, this functionality will be fine and lead to faster prototyping]

The javascript client side library is able to use gazebo transport to send and receive the protobuf messages. So you could subscribe to messages and communicate with a (custom) plugin. You cannot directly use the C++ API's for sytem, world and objects. There should be something running within the simulator to modify the state.

If you would like to use python, take a look at this library: https://github.com/jpieper/pygazebo
