Usage

This guide demonstrates building a complete blog system using Advanced Alchemy’s features. We’ll create a system that supports:

• Posts with tags and slugs

• Tag management with automatic deduplication

• Efficient querying and pagination

• Type-safe database operations

• Schema validation and transformation

Core Features

• Modeling
• Repositories
• Services
• Utilities

Framework Integration

• Litestar Integration
• FastAPI Integration

The guide follows a practical approach:

1. Modeling: Define SQLAlchemy models with Advanced Alchemy’s enhanced base classes

2. Repositories: Implement type-safe database operations using repositories

3. Services: Build business logic with automatic schema validation

4. Framework Integration: Integrate with Litestar and FastAPI

Each section includes:

• Concepts and usage overview

• Complete code examples

• Best practices

• Performance considerations

• Error handling strategies

Prerequisites

• Python 3.8+

• SQLAlchemy 2.0+

• Pydantic v2 or Msgspec (for schema validation)

• Basic understanding of SQLAlchemy and async programming

• Basic understanding of Pydantic or Msgspec
