SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Many codebases suffer from runtime type errors, inconsistent API contracts, and poor developer ergonomics due to weak or poorly designed TypeScript types; this Skill helps eliminate those issues by designing robust, maintainable type systems and build configurations that prevent class of bugs at compile time.

Core Features & Use Cases

  • Advanced type system design: Craft generics, conditional types, mapped types, template literal types, and branded types for precise domain modeling.
  • Runtime safety with compile-time guarantees: Produce type guards, discriminated unions, and assertion functions to narrow types safely at runtime.
  • Full-stack and library support: End-to-end typing for tRPC and API clients, declaration file generation for libraries, and project reference / monorepo tsconfig setups.
  • Build and performance optimization: Configure strict compiler flags, incremental builds, declaration maps, and strategies for smaller bundles and faster type-checks.
  • Use Case: Convert an untyped REST client and backend DTOs into a single source of truth with fully typed request/response contracts and automated type guards for edge-case handling.

Quick Start

Ask the TypeScript Pro to analyze your project and produce a strict tsconfig, typed API contracts, and necessary type guards tailored for production.

Frequently Asked Questions about typescript-pro

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure a strict tsconfig for production-grade TypeScript?

Configure a strict tsconfig for production TypeScript by enabling strict compiler flags, incremental builds, declaration maps, and project references. This setup prevents runtime type errors and optimizes build performance for large-scale applications.

How do I create type-safe API contracts with tRPC and TypeScript?

Create type-safe API contracts with tRPC by designing end-to-end typed request and response schemas. This approach unifies untyped REST clients and backend DTOs into a single source of truth, eliminating inconsistent API contracts.

What are the best ways to use TypeScript generics and conditional types for domain modeling?

The best way to use TypeScript generics and conditional types for domain modeling is crafting advanced type systems with mapped types, template literal types, and branded types. This ensures precise compile-time correctness and robust domain representation.

How do I implement type guards and discriminated unions for runtime type safety?

Implement type guards and discriminated unions for runtime type safety by producing assertion functions that narrow types safely at runtime. This technique provides compile-time guarantees while safely handling edge-case data.

Does TypeScript Pro support declaration file generation for libraries?

Yes, TypeScript Pro supports declaration file generation for libraries. It configures declaration maps and project reference setups for monorepos, ensuring proper type exports and optimized build performance for library development.
