SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? TypeScript projects often suffer from loose typing, inconsistent compiler configurations, and fragile type contracts that let runtime errors slip into production. This Skill guides the design and implementation of type-safe TypeScript codebases with strict checking and well-modeled contracts. ## Core Features & Use Cases - Advanced Type Modeling: Designs generics, conditional types, mapped types, and custom utility types for complex domain models. - Strict Configuration: Sets up tsconfig compiler flags, linting safeguards, and incremental compilation for fast, safe builds. - Typed Testing & Declarations: Produces Jest/Vitest tests with type assertions and .d.ts declaration files for external libraries. - Use Case: When refactoring a Node.js/Express API, use this Skill to define shared interfaces, enforce strict null checks, and generate typed error boundaries across the service layer. ## Quick Start Ask the agent to review your TypeScript project and design strict, generic type contracts for your core modules with matching typed tests.

FAQPage Schema
How do I enforce strict type safety in a TypeScript project?

Enable strict compiler flags in tsconfig such as strict mode, and model critical surfaces with explicit interfaces and generics. Combine this with linting safeguards and typed tests to catch type errors at build time.

How to write generic functions with proper type constraints in TypeScript?

Define generic type parameters with extends clauses to constrain accepted types, and prefer inference over explicit annotations when the compiler can resolve types clearly. Use utility types like Pick, Omit, and mapped types for reusable transformations.

Can I use this TypeScript guidance with React or Node.js projects?

Yes, the approach covers integration with modern frameworks including React, Node.js, and Express. It focuses on typed props, API contracts, and typed error boundaries applicable across these stacks.

When should I not use strict TypeScript typing?

Avoid it when the project is plain JavaScript without TypeScript in the build pipeline, or when the task is UI/UX design rather than type design. Gradual typing is supported for migration scenarios.

Why does TypeScript inference fail on complex generic types?

Inference breaks down with deeply nested generics, circular references, or missing constraints. Fix it by adding explicit type annotations at boundaries, simplifying conditional types, or restructuring generics with clearer constraints.
