Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex type logic, creating reusable type utilities, or ensuring compile-time type safety in TypeScript projects.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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.
## When to Use This Skill
- 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
## Core Concepts
### 1. Generics
**Purpose:** Create reusable, type-flexible components while maintaining type safety.
**Basic Generic Function:**
```typescript
function identity<T>(value: T): T {
return value;
}
const num = identity<number>(42); // Type: number
const str = identity<string>("hello"); // Type: string
const auto = identity(true); // Type inferred: boolean
```
**Generic Constraints:**
```typescript
interface HasLength {
length: number;
}
function logLength<T extends HasLength>(item: T): T {
console.log(item.length);
return item;
}

How to install
mdr add asymmetric-al/core/typescript-advanced-types@sha256:302d9b66d727e6daThe line at the top of this page pins the label git:20260923.15c9348, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
