typeclass-design

What problem does it solve?

This skill enables designing reusable abstractions by enforcing fully curried typeclass functions and dual APIs for both data-first and data-last usage.

Core Features & Use Cases

• Fully currying typeclass functions to enable partial application and space for extensions.
• Dual APIs using Function.dual to support both data-first and data-last usage patterns.
• Examples and patterns for common typeclasses (e.g., Durable) and helpers like isMoreThan and OrderByDuration using a TypeScript/HKT-like approach.
• Use Case: Build a generic Durable type and derive operations that can be piped or called directly.

Quick Start

Define a Durable interface and implement a curried function using the dual API pattern, then invoke it in both data-first and data-last styles as shown in the examples.
