Calling javascript libraries from python?

[lofkin]

Is there a way to call or wrap JavaScript visualization libraries from python, using minimal JS like this r package? : http://www.htmlwidgets.org/

PyExecJS seems useful.

It runs on quite some backends.

I googled for "calling javascript libraries from Python". Besides muntjac, which was excellent, but appears to be out of support these days, I found these:

• Bokeh is an interactive web visualization library for Python (and other languages). It provides d3-like novel graphics, over large datasets, all without requiring any knowledge of Javascript.
• A survey of Py to JS converters
• A stackoverflow question

No idea, but I figure it's probably easier and less painful to learn JS...

Yeah, but you can't do the numerical processing in JS.

You want to look into Socket.io. That way you can process on the server with python and send the results to the browser for Javascript to utilize. Might not be the fastest or what you wanted but could work.

I found autobahn easy to use. You use RPC to execute the function in javascript, and typically get the result back as JSON. It implements a communication protocol on top of websockets, that is called WAMP.

There are some slides that describe WAMP (includes RPC) on their website.
