<div dir="ltr"><div>Brian,<br><br></div><div>So it seems that for us to get some data from a python object into our javascript, we write the data to file on the fly so that a js cell can pull it in from the filesystem or we hard code the data into the js string. Is that the way it should be done with the current setup?<br>
<br></div><div>So we'd like the functionality for GET/POST in the notebook for our project. And I have one full time student that starts this week. What would be the best way for us to contribute some patches to jumpstart this on the ipython side?<br>

Right now it does not have any easy way of doing that. For now you<br>
will have to encode your data into the call to kernel.execute, which<br>
is a completely pain. That is exactly what we will be tackling later<br>
in the summer...<br>
