Typescript Advanced Types
If you're building type-safe libraries, complex generics, or migrating a JavaScript codebase to TypeScript, this gives you structured guidance on the advanced type system. It covers conditional types, mapped types, template literals, and utility types with a focus on practical application rather than academic explanation. The skill includes an implementation playbook with concrete patterns, which is helpful since advanced types can get abstract quickly. Best for scenarios where you need proper type inference or are designing reusable components where getting the types wrong means runtime surprises. Not much value if you're just adding basic type annotations to existing code.

TypeScript Advanced Types
Comprehensive guidance for mastering TypeScript's advanced type system including generics, conditional types, mapped types, template literal types, and utility types for building robust, type-safe applications.
Use this skill when
- Building type-safe libraries or frameworks
- Creating reusable generic components
- Implementing complex type inference logic
- Designing type-safe API clients
- Building form validation systems
- Creating strongly-typed configuration objects
- Implementing type-safe state management
- Migrating JavaScript codebases to TypeScript
Do not use this skill when
- The task is unrelated to typescript advanced types
- You need a different domain or tool outside this scope
Instructions
- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
- If detailed examples are required, open
