📐 Overview

This tutorial walks you through deploying and integrating the Financial Research Assistant chatbot on your proprietary platform using a sample Python server chat-server.py and connecting it to Bigdata.com’s Chat Service. Flow Summary:

The Web App sends users’ inputs to the Python-based chat server chat-server.py.
The server processes these inputs and communicates with Bigdata.com’s Chat Service API.
Responses are routed back to the Web App for display.

🧰 Prerequisites

Create a directory for your project and navigate to it.

mkdir chat-server
cd chat-server/

Follow the how-to guide Prerequisites to set up your Bigdata.com Python SDK environment.

🧪 Step 1: Set Up chat-server.py

Place the files chat-server.py and requirements.txt in your project directory.

    db.chat.delete(chat_id)
    print(f"[INFO] Deleted chat with ID: {chat_id}")

    return jsonify({"message": "Chat deleted successfully"})

def _build_cors_preflight_response():
    response = jsonify({})
    response.headers.add("Access-Control-Allow-Origin", "*")
    response.headers.add("Access-Control-Allow-Methods", "GET, POST, OPTIONS, DELETE")
    response.headers.add("Access-Control-Allow-Headers", "Content-Type")
    return response

if __name__ == "__main__":
    app.run(debug=True, port=5000)

requirements.txt

Project structure:

chat-server/
├── bigdata_venv/
├── .env
├── chat-server.py
└── requirements.txt

Install dependencies:

pip install -r requirements.txt

Run the server:

python chat-server.py

By default, this starts on http://localhost:5000 unless specified otherwise.

🧑‍💻 Step 2: Connect from Your Web App

We built a Sample App that you can use as PoC. By default it communicates to the chat-server.py on http://localhost:5000
