Here’s your text rewritten into a clear, professional, and implementation-ready prompt — ideal for precise backend refactoring work and code movement between modules:

🧩 Task: Refactor and Modularize app.py

Objective:
Begin restructuring the main app.py file based on the earlier recommendations for modularization and performance improvement.
The goal is to split related logic into separate, focused modules while ensuring full functionality and seamless integration with the rest of the system.

Refactoring Requirements

1. New Module Creation
   Create two new Python modules and move relevant sections of logic from app.py into them:

   • db_init.py → Responsible for database initialization, connection setup, and schema loading.

   • articles_service.py → Responsible for article-related functionality such as queries, parsing, and data retrieval.

2. Workload Distribution

   • You will provide the complete code that needs to go into each of these two files (db_init.py and articles_service.py).

   • Clearly specify the exact code blocks to be removed from app.py after relocation.

     • Include two lines before and two lines after each section to help locate and remove them precisely.

3. Integration Instructions
   After moving the code:

   • Explain how to properly import and call the functions or classes from db_init.py and articles_service.py within app.py.

   • Verify that all internal dependencies and references remain stable.

   • Ensure the integration between these modules is fully functional and no runtime or circular import issues occur.

4. Final Validation

   • The refactored system must run identically to the current implementation.

   • No functionality, routes, or data flow should be broken.

   • The structure should be cleaner, more modular, and easier to maintain.

✅ Expected Deliverables

• The full code contents of:

  • db_init.py

  • articles_service.py

• A list of exact code removal locations in app.py (with context lines).

• Instructions for imports and integration validation in app.py.

• Any additional setup or configuration steps needed to ensure everything runs smoothly post-refactor.

Would you like me to include an example project structure diagram showing how app.py, db_init.py, and articles_service.py will be organized and imported after this change?
