simple todo app with fastapi and in-memory storage

[rnagulapalle]

Summary

A lightweight Todo REST API built with FastAPI and in-memory storage, providing full CRUD operations for managing todo items. The application follows a clean modular architecture with separate concerns for models, storage, routing, and application entry point. This is a foundational service suitable for prototyping, demos, and as a starting point for more advanced task management features.

Changes

• feat: Implemented FastAPI application with five CRUD endpoints: create (POST /todos), list all (GET /todos), get by ID (GET /todos/{id}), update (PUT /todos/{id}), and delete (DELETE /todos/{id})
• feat: Added in-memory storage module (store.py) with a global dictionary-based store and helper functions for all CRUD operations, including proper 404 handling for missing items
• feat: Created Pydantic data models (models.py) for request validation (TodoCreate, TodoUpdate) and response serialization (TodoResponse) with type annotations
• feat: Built modular route layer (routes.py) with a dedicated APIRouter for clean separation from the main application entry point
• feat: Created main.py entry point with FastAPI app initialization, router inclusion, and uvicorn server configuration
• test: Added comprehensive unit and integration tests using FastAPI TestClient covering all CRUD operations, success paths, and 404 error responses
• docs: Added PLANNING.md with architectural decisions and RUNNING.md with setup and startup instructions

Testing

Comprehensive test suite using FastAPI TestClient and pytest covering all five CRUD endpoints, including successful operations, 404 error handling for missing todo items on get/update/delete, and response payload validation. Note: a truncated test function was identified during code review and should be verified before production use.
