This deliverable provides the foundational Python backend code for your Custom Chatbot Builder, integrating directly with Google's Gemini Pro model. This step focuses on generating clean, well-commented, and production-ready code that handles user input, communicates with the AI model, and manages conversation history.
The generated code utilizes Flask for the web server, google-generativeai for Gemini integration, and python-dotenv for secure environment variable management.
The following components are provided to establish the core functionality of your chatbot backend:
app.py: The main Flask application file containing the API endpoints for chat interaction and health checks. It manages session-based conversation history and integrates with the Gemini API.config.py: A configuration file to centralize settings, though for simplicity and security, API keys are primarily handled via environment variables.requirements.txt: Lists all necessary Python packages for easy environment setup..env.example: An example file demonstrating how to set up environment variables for sensitive information like your Gemini API key.app.py - Main Chatbot Backend ApplicationThis file sets up the Flask server, configures the Gemini model, and defines the /chat endpoint for handling user messages and maintaining conversation context.
#### 2.2. `config.py` - Configuration (Optional for this setup) While API keys are handled via environment variables, this file can be expanded for other application-specific configurations.
