Quick Start

It's super easy to get started with Panel chat components.

  1. Setup imports
  2. Define a function to dictate what to do with the input message
  3. Define a servable widget with callback=response_callback
# 1.)
import panel as pn
pn.extension()

# 2.)
def response_callback(input_message: str, input_user: str, instance: pn.chat.ChatInterface):
    # choose your favorite LLM API to respond to the input_message
    ...
    response_message = f"Echoing your input: {input_message}"
    return response_message

# 3.)
pn.widgets.ChatInterface(callback=response_callback).servable()
