haiway 0.42.0

Framework for dependency injection and state management within structured concurrency model.

🚗 haiway 🚕 🚚 🚙

Modern Python framework for functional programming with structured concurrency

Haiway brings functional programming principles to Python's async ecosystem, providing a robust foundation for building scalable, maintainable applications with immutable state management and automatic resource cleanup.

Why Haiway?

Building concurrent Python applications often involves complex state management, dependency injection frameworks, and careful resource handling. Haiway simplifies these challenges through:

🔒 Immutability First

Type-safe data structures that prevent race conditions and ensure predictable behavior in concurrent environments

⚡ Zero-Config DI

Context-based dependency injection without decorators, containers, or complex frameworks

🎯 Functional Design

Pure functions and explicit data flow make code easier to understand, test, and maintain

🔄 Structured Concurrency

Automatic task lifecycle management with guaranteed cleanup, even in error cases

Core Principles

🎯 Type Safety Throughout

Full type checking with modern Python features - unions, generics, protocols. Runtime validation ensures data integrity.

🧩 Composable Building Blocks

Small, focused components that combine into larger systems. No framework lock-in or magic.

🔄 Explicit Over Implicit

Dependencies are visible in type signatures. No hidden global state or surprising side effects.

🎭 Async-Native

Built for Python's async/await from the ground up. Includes utilities for retries, timeouts, and concurrent operations.

🖥️ Install

With pip:
