This example shows a frontend comm target registered in a registry: Jupyter.notebook.kernel.comm_manager.register_target('my_comm_target', function(comm, msg) { // comm is the frontend comm instance the message # Send data to the frontend comm.send({'foo': 5}) get_ipython().kernel.comm_manager.register_target('my_comm_target', target_func) This example uses the IPython kernel again; this for comms support. And then open the comm from the frontend: comm = Jupyter.notebook.kernel.comm_manager.new_comm('my_comm_target', {'foo': 6}) // Send
