The Narrative Generator

The DynamWorks Narrative Generator serves as a prime example of how we can rapidly bring complex, AI-integrated ideas to life. It demonstrates our ability to leverage cutting-edge technologies while ensuring the final product is scalable, secure, and aligned with business objectives. This showcase highlights our expertise in modern application development, cloud architecture, and AI integration, providing a powerful tool for generating narrative content on demand.

Application Overview

The Narrative Generator is a web application that leverages AI models to create dynamic narrative content based on user input. This project showcases our ability to rapidly develop and deploy complex, AI-integrated applications using React for the frontend and Node.js for the backend, all running on AWS infrastructure.

Key Features:

  • User-friendly interface for topic input

  • AI-powered narrative generation using multiple models (OpenAI, Anthropic's Claude)

  • Scalable architecture to handle varying loads

  • Secure handling of API keys and user data

  • Responsive design for various device sizes

Technical Deep Dive

Frontend

  • Technology: React

  • Key Components:

    • User input form for topic submission

    • Model selection dropdown (currently featuring OpenAI)

    • Dynamic narrative display as a series of cards

  • Development Approach:

    • React-based Single Page Application (SPA)

    • State management using React hooks (useState, useEffect, useCallback)

    • API service layer using Axios for backend communication

    • Responsive design with custom CSS

    • Comprehensive error handling for improved user experience

Backend

  • Technology: Node.js with Express

  • Key Features:

    • RESTful API for narrative generation

    • Integration with multiple AI providers (OpenAI, Anthropic's Claude)

    • Secure retrieval of API keys from AWS Secrets Manager

    • CORS support for secure cross-origin requests

    • Basic request logging middleware

  • Development Approach:

    • Modular design with separate components for AI initialization and narrative generation

    • Flexible model selection allowing easy addition of new AI providers

    • Robust error handling for AI initialization and narrative generation processes

AWS Deployment

  • Key Services Used:

    • AWS Amplify for frontend hosting

    • Elastic Container Service (ECS) or Elastic Beanstalk for backend deployment (inferred)

    • Secrets Manager for secure API key storage

    • CloudWatch for logging and monitoring (inferred)

  • Deployment Strategy:

    • Frontend hosted on AWS Amplify for fast global content delivery

    • Backend containerized for easy deployment and scaling

    • Use of environment variables for flexible configuration across environments
