# Research Findings
## Decision: Use `httpx` for asynchronous HTTP requests
**Rationale**: The existing application uses FastAPI, which is an asynchronous framework. The `requests` library is synchronous and will block the event loop, degrading performance. `httpx` provides a similar API to `requests` but is fully asynchronous, making it the ideal choice for this project.
**Alternatives considered**: Using `requests` in a thread pool. This is a viable option but is more complex to implement and maintain than using a native async library like `httpx`.
## Decision: Use SQLAlchemy with `asyncpg` for database integration
**Rationale**: SQLAlchemy is a powerful and widely used ORM for Python that supports asynchronous operations with the `asyncpg` driver. This allows for non-blocking database calls, which is essential for a FastAPI application. It also provides a robust way to manage database sessions and connection pooling.
**Alternatives considered**:
- **Using a synchronous ORM**: This would block the event loop and is not recommended for FastAPI.
- **Writing raw SQL queries**: This is more error-prone, less secure (risk of SQL injection), and harder to maintain than using an ORM.
- **SQLModel**: While SQLModel is a good option, SQLAlchemy is more mature and has a larger community. Since the project already uses SQLAlchemy, it's better to stick with it for consistency.
## Decision: Use Pydantic `BaseSettings` for configuration management
**Rationale**: Pydantic's `BaseSettings` provides a convenient way to manage application settings and secrets from environment variables. This keeps sensitive information out of the codebase and makes the application more portable across different environments.
**Alternatives considered**:
- **Hardcoding configuration**: This is insecure and makes the application difficult to configure.
- **Using `.ini` or `.json` files**: This is a viable option, but Pydantic's `BaseSettings` provides validation and type hinting, which makes the configuration more robust.
