Telegram ChatBot with ElasticSearch and ChatGPT Integration

This Node.js application integrates a Telegram chatbot with ElasticSearch for search functionalities and utilizes ChatGPT for generating conversational responses. It fetches search results from ElasticSearch based on user queries received via Telegram, then prompts ChatGPT with contextual information to generate relevant responses.

Setup Instructions

1. Install Dependencies

   • Ensure you have Node.js installed on your system.
   • Run npm install to install the required dependencies specified in package.json.

2. Environment Variables

   • Create a .env file in the root directory.
   • Add the following environment variables to the .env file:

     BOTTOKEN=YOUR_TELEGRAM_BOT_TOKEN
     ELKAPIKEY=YOUR_ELASTICSEARCH_API_KEY
     VTIGPTKEY=YOUR_CHATGPT_API_KEY
     ELKURL=YOUR_ELASTICSEARCH_URL
     ELKUSER=YOUR_ELASTICSEARCH_USERNAME
     ELKPASS=YOUR_ELASTICSEARCH_PASSWORD
     

   • Replace YOUR_TELEGRAM_BOT_TOKEN, YOUR_ELASTICSEARCH_API_KEY, YOUR_CHATGPT_API_KEY, YOUR_ELASTICSEARCH_URL, YOUR_ELASTICSEARCH_USERNAME, and YOUR_ELASTICSEARCH_PASSWORD with your respective API keys and Elasticsearch credentials.

3. Telegram Bot Initialization

   • Create a new Telegram bot using BotFather.
   • Obtain the bot token and replace YOUR_TELEGRAM_BOT_TOKEN with it in the .env file.

4. ElasticSearch Setup

   • Set up an instance of ElasticSearch and obtain the necessary credentials.
   • Replace YOUR_ELASTICSEARCH_API_KEY, YOUR_ELASTICSEARCH_URL, YOUR_ELASTICSEARCH_USERNAME, and YOUR_ELASTICSEARCH_PASSWORD with your ElasticSearch configuration.

5. ChatGPT Setup

   • Obtain an API key for ChatGPT from the OpenAI platform.
   • Replace YOUR_CHATGPT_API_KEY with your ChatGPT API key in the .env file.

6. Running the Application

   • Execute node index.js to start the application.
   • Your Telegram bot is now active and ready to respond to messages.

Usage

• Send messages to your Telegram bot to trigger responses.
• The bot will search for relevant content in ElasticSearch based on the received message and generate responses using ChatGPT.

Additional Notes

• Ensure your ElasticSearch instance is configured correctly and contains the necessary data for search functionality.
