Gemini API Chatbot

This project provides simple command-line chatbots for Google's Gemini API in both Python and Node.js.

Features

  • Chat with Gemini using the latest high-throughput model (gemini-2.5-flash)
  • Works in both Python and Node.js
  • Easy to run from the terminal

Requirements

  • Node.js v18+ (for Node.js chatbot)
  • Python 3.9+ (for Python chatbot)
  • A valid Gemini API key from Google AI Studio

Setup

  1. Clone or download this repository.
  2. Install dependencies:
  3. For Python: 
    pip install -r requirements.txt
  4. For Node.js: 
    npm install
  5. Set your Gemini API key:
  6. The API key is currently set directly in both chatbot.py and chatbot.js for demonstration.
  7. Recommended for production: Use a .env file to store your API key securely.
  1. Create a file named .env in your project root: 
    GEMINI_API_KEY=your_actual_gemini_api_key_here
  2. Update your code:
  3. For Python, make sure you have these lines at the top: 
    from dotenv import load_dotenv
load_dotenv()
    And use os.getenv("GEMINI_API_KEY") to access the key.
  4. For Node.js, add this at the top: 
    import 'dotenv/config';
    And use process.env.GEMINI_API_KEY to access the key.
  5. Remove the hardcoded API key from your code for security.

Usage

Python

Run the chatbot with: 

python chatbot.py
Type your message and press Enter. Type exit to quit.

Node.js

Run the chatbot with: 

node chatbot.js
Type your message and press Enter. Type exit to quit.

File Overview

  • chatbot.py: Python CLI chatbot using the Gemini API.
  • chatbot.js: Node.js CLI chatbot using the Gemini API.
  • requirements.txt: Python dependencies.
  • package.json: Node.js dependencies.
  • README.md: This documentation file.

Security Note

Never share your API key publicly. For production, always use environment variables or a .env file to keep your key secure.

Gemini API Chatbot (USES Gemini API)

This utility uses the Gemini API for AI chat. All other logic and data are managed locally for learning and experimentation.

This project provides simple command-line chatbots for Google's Gemini API in both Python and Node.js.

Features

  • Chat with Gemini using the latest high-throughput model (gemini-2.5-flash)
  • Works in both Python and Node.js
  • Easy to run from the terminal
  • Beginner-friendly: All code is commented for learning

Requirements

  • Node.js v18+ (for Node.js chatbot)
  • Python 3.9+ (for Python chatbot)
  • A valid Gemini API key from Google AI Studio

Setup

  1. Clone or download this repository.
  2. Install dependencies:
  3. For Python: 
    pip install -r requirements.txt
  4. For Node.js: 
    npm install
  5. Set your Gemini API key:
  6. The API key is currently set directly in both chatbot.py and chatbot.js for demonstration.
  7. Recommended for production: Use a .env file to store your API key securely.

Usage Workflow (Step-by-Step)

  1. Run the chatbot:
  2. For Python: 
    python chatbot.py
  3. For Node.js: 
    node chatbot.js
  4. Type your message and press Enter. Type exit to quit.

Educational Notes

  • How does it work? The chatbot sends your message to the Gemini API and prints the response.
  • How is the code structured? Each function is commented to explain its purpose. The code is designed for easy modification.
  • How can you extend it? Try adding conversation history, or integrating with a GUI!

Security Note

Never share your API key publicly. For production, always use environment variables or a .env file to keep your key secure.
