On SDK Design

In a reflective piece on the evolution of Hatchet's Python SDK, the author discusses the transformation of the SDK from being cumbersome and unintuitive to a user-friendly and efficient tool inspired by popular libraries like FastAPI and Celery. Hatchet's approach to SDK development centers on three principles: familiarity, opinionated guidance, and continuous learning. By drawing inspiration from established Python tools, the SDK aims to provide a seamless transition for developers familiar with FastAPI or Celery, enabling them to quickly adapt without extensive documentation. The SDK is designed to guide developers along the "happy path," promoting best practices and type safety through opinionated design choices, such as the use of Pydantic for type validation. To foster continuous learning, the SDK is self-documenting with verbose naming and type hints, complemented by human-written documentation and educational content on their blog. These principles collectively ensure that developers can focus on building scalable solutions while minimizing time spent on troubleshooting and documentation navigation.
