Framework for dependency injection and state management within structured concurrency model.
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.
Building concurrent Python applications often involves complex state management, dependency injection frameworks, and careful resource handling. Haiway simplifies these challenges through:
Type-safe data structures that prevent race conditions and ensure predictable behavior in concurrent environments
Context-based dependency injection without decorators, containers, or complex frameworks
Pure functions and explicit data flow make code easier to understand, test, and maintain
Automatic task lifecycle management with guaranteed cleanup, even in error cases
Full type checking with modern Python features - unions, generics, protocols. Runtime validation ensures data integrity.
Small, focused components that combine into larger systems. No framework lock-in or magic.
Dependencies are visible in type signatures. No hidden global state or surprising side effects.
Built for Python's async/await from the ground up. Includes utilities for retries, timeouts, and concurrent operations.
With pip:
pip install haiway
