SQLAlchemy 2.0+

What problem does it solve?

Async, type-safe ORM for Python backends requires careful setup to avoid boilerplate and runtime errors; SQLAlchemy 2.0+ provides a modern approach to modeling and async querying.

Core Features & Use Cases

• Declarative, type-safe models with Mapped attributes and relationships for robust data layers.
• Async engine and session management to handle high-concurrency backends with asyncio.
• Use Case: Build an API service that performs scalable CRUD and complex queries against PostgreSQL or SQLite while maintaining strict typing.

Quick Start

Install SQLAlchemy 2.0+ and an async driver, then configure an AsyncEngine and an async sessionmaker to run CRUD operations in an async context.
