description Overview

Extract Interface from Type Alias (TypeScript)

Extract Interface from Type Alias in TypeScript allows developers to define explicit interfaces from existing type aliases, improving code structure and type safety. The IDE automatically generates the interface definition and updates references. This refactoring enhances code maintainability, facilitates code reuse, and provides better type checking capabilities.

Extract Interface from Class

A specialized version of Extract Type, this tool specifically targets extracting the *public contract* of a class into an interface. It analyzes which methods are called externally versus which are internal implementation details, guiding the developer to define the minimal necessary public API contract. This is the safest way to prepare a class for dependency inversion.
