How to build a custom chatbot using ChainLit? 

‍

Step 1. Prerequisites

💡 Make sure you have the following libraries installed: chainlit, requests, json, dotenv, os

import chainlit as cl
import requests
import json
from dotenv import load_dotenv
import os
from typing import Optional
from chainlit.types import ThreadDict
from chainlit.input_widget import Select, Slider

‍

Step 2. Decorator and Chat Settings

Chainlit works with decorators for handling interactions,  so you will need to use it for each of the interaction you want to handle. Here's an example decorator, followed by the function that will be triggered when a new message is posted.

@cl.on_message #The decorator
async def main(message: cl.Message):
   await cl.Avatar(
       name="AskYoda",
       path = "public/logo_light.png"   
       ).send()

‍

You can also customize chat settings using cl.ChatSettings in the triggered function:

cl.ChatSettings(
       [
           Select(
               id="llm_provider", 
               label="LLM Provider",
               values=["cohere", "amazon", "anthropic", "ai21labs", "openai", "google"],
               initial_index = 4          
               ),
           Select(
               id="llm_model",
               label="LLM Model",
               values= [
                   "command",
                   "command-light"
)])

‍

Step 3. Retrieve Chat Settings

You can retrieve the selected chat settings like this:

llm_model = cl.user_session.get("llm_model")
llm_provider = cl.user_session.get("llm_provider")

‍

Step 5. Make API Calls to your Custom AI Chatbot

Before making API calls, ensure you have the bearer token and project ID ready:

headers = {"Authorization": f"Bearer {Api_Key}"}
url = f"https://api.edenai.run/v2/aiproducts/askyoda/{project_id}/ask_llm"

‍

Then, gather all the necessary information and make the API call to Eden AI:

json_payload = {"query" : f"{message.content}",
           "llm_provider" : llm_provider,
           "history" : history,
           "llm_model" : llm_model,
           #Customize the personnality of your assistant
           "personnality" : {},
           "chunks" : chunks
           }
   response = requests.post(url, json=json_payload, headers=headers)
   result = json.loads(response.text)

   if 'result' in result:
       a = str(result['result'])
       history.append({"user": f"{message.content}", "assistant": f"{a}"})
       # Send a response back to the user
       await cl.Message(
           content=f"{result['result']}", author = 'AskYoda'


       ).send()
   else:
       await cl.Message(
           content=f"Key 'result' not found in the response.  : {result}",
       ).send()

‍
