Implementation Plan for Athena DeepCite Refactoring

This document outlines a comprehensive plan for refactoring the Athena DeepCite extension while ensuring it remains functional in a browser environment.

Phase 1: Setup

  1. Add Webpack for bundling

    • Install webpack and related packages
    • Create a webpack configuration file
    • Configure TypeScript to work with webpack

  2. Update project structure

    • Create src directory with subdirectories
    • Move existing TypeScript files to appropriate locations
    • Set up path aliases in tsconfig.json

Phase 2: Modularization

  1. Extract type definitions

    • Move all interfaces to types.ts
    • Define common interfaces for extractors and handlers

  2. Refactor PDF handling

    • Extract PDFHandler class to its own file
    • Create a dedicated PDFAnalyzer for UI components

  3. Refactor content extraction

    • Implement IExtractor interface
    • Move ContentExtractor to its own file
    • Update LLMExtractor to implement the interface

  4. Create settings manager

    • Centralize API key management
    • Add caching for better performance
    • Create utility functions for storage access

Phase 3: Message Handling

  1. Refactor background script

    • Implement message router pattern
    • Create handler functions for each message type
    • Document the message flow

  2. Update content script

    • Simplify to focus on initialization and delegation
    • Add proper error handling
    • Improve logging for troubleshooting

Phase 4: Build and Testing

  1. Update build process

    • Create npm scripts for development and production builds
    • Add watch mode for faster iteration
    • Configure source maps for debugging

  2. Add ESLint and formatting

    • Install and configure ESLint
    • Add TypeScript-specific rules
    • Create npm script for linting

  3. Test across browsers

    • Test in Chrome
    • Test in Firefox (if supporting)
    • Verify functionality on different websites

Phase 5: Documentation

  1. Update code documentation

    • Add JSDoc comments to all public methods
    • Document message formats
    • Document extension architecture

  2. Create user documentation

    • Update README with new features
    • Create troubleshooting guide
    • Document testing procedures

Timeline

Phase Estimated Time Description
Phase 1 1-2 days Setup bundling and project structure
Phase 2 2-3 days Modularize the codebase
Phase 3 1-2 days Refactor messaging system
Phase 4 1-2 days Testing and build process
Phase 5 1 day Documentation and final touches

Immediate Next Steps

  1. Install webpack and configure it
  2. Create the src directory structure
  3. Update tsconfig.json for the new structure
  4. Begin extracting modules while keeping the extension functional
