This skill should be used when the user asks to "optimize TypeScript performance", "speed up tsc compilation", "configure tsconfig.json", "fix type errors", "improve async patterns", or encounters TS errors (TS2322, TS2339, "is not assignable to"). Also triggers on .ts, .tsx, .d.ts file work involving type definitions, module organization, or memory management. Does NOT cover TypeScript basics, framework-specific patterns, or testing.
TypeScript strict mode configuration for 2025. Recommended tsconfig.json settings, strict flags explained, moduleResolution strategies (Bundler vs NodeNext), verbatimModuleSyntax, noUncheckedIndexedAccess. Use when setting up TypeScript projects or migrating to stricter type safety.
TypeScript best practices and patterns for writing type-safe, maintainable code. Use when working with TypeScript files, configuring tsconfig, defining interfaces/types, implementing error handling, writing generics, or setting up type-safe communication patterns. Includes patterns for discriminated unions, type guards, utility types, and more.
TypeScript 6+ guidance for project development, tsconfig configuration, diagnostics, module resolution, deprecations, and modern standard-library typings. Use when building or maintaining TypeScript 6+ projects, debugging compiler behavior, or working through TS 6-specific defaults and tooling such as `#/` subpath imports, `ignoreDeprecations`, `RegExp.escape`, `Temporal`, and `--stableTypeOrdering`. Triggers on typescript 6, ts 6, stableTypeOrdering, ignoreDeprecations, types array, noUncheckedSideEffectImports, baseUrl deprecated, moduleResolution node deprecated, and subpath imports.
Use TypeScript for type-safe JavaScript: types, interfaces, generics, narrowing, tsconfig, modules, and strict mode. Use when writing or reviewing TypeScript, configuring tsconfig.json, defining types or interfaces, generics, type inference, or when the user mentions TypeScript, TS, or type checking.
TypeScript language expertise covering the type system, generics, utility types, advanced type patterns, and project configuration. Use this skill whenever writing, reviewing, or refactoring TypeScript code, designing type-safe APIs, working with complex generics, debugging type errors, configuring tsconfig.json, migrating JavaScript to TypeScript, or leveraging TypeScript 5.x features like satisfies, const type parameters, decorators, and the using keyword. Also use when the user asks about type narrowing, conditional types, mapped types, template literal types, branded types, discriminated unions, or any TypeScript type system question — even seemingly simple ones, because TypeScript's type system has subtle gotchas that catch experienced developers.
TypeScript 타입 정의 및 베스트 프랙티스 스킬. 다음 상황에서 사용: (1) TypeScript 파일(.ts, .tsx) 작성 또는 수정 시, (2) 타입 정의(interface, type) 작업 시, (3) tsconfig.json 설정 또는 컴파일러 옵션 조정 시, (4) 타입 에러 해결 또는 타입 안전성 개선 시, (5) 제네릭, 유틸리티 타입, 타입 조작 작업 시, (6) 'typescript', 'ts', 'type', 'interface', 'generic' 키워드가 포함된 작업 시
TypeScript best practices, type safety, and toolchain standards. Use when: - Writing or reviewing TypeScript code - Setting up TypeScript projects or tsconfig - Choosing state management patterns - Configuring build tools (tsup, Vitest) - Avoiding type gymnastics or any-abuse Keywords: TypeScript, tsconfig, strict mode, no-any, pnpm, Vitest, tsup, TanStack Query, discriminated unions, type safety, ESLint
Modern TypeScript 7.0 preferences for strict typing, tsconfig, narrowing, generics, declaration design, native tooling, and 6.0-to-7.0 compatibility work.
Use skill if you are writing or reviewing framework-agnostic TypeScript and need strict typing, tsconfig/lint decisions, safer refactors, or guidance on generics, unions, and typed boundaries.
Provides domain-specific best practices for Node.js development with TypeScript, covering type stripping, async patterns, error handling, streams, modules, testing, performance, caching, logging, and more. Use when setting up Node.js projects with native TypeScript support, configuring type stripping (--experimental-strip-types), writing Node 22+ TypeScript without a build step, or when the user mentions 'native TypeScript in Node', 'strip types', 'Node 22 TypeScript', '.ts files without compilation', 'ts-node alternative', or needs guidance on error handling, graceful shutdown, flaky tests, profiling, or environment configuration in Node.js. Helps configure tsconfig.json for type stripping, set up package.json scripts, handle module resolution and import extensions, and apply robust patterns across the full Node.js stack.
Link workspace packages in monorepos (npm, yarn, pnpm, bun). USE WHEN: (1) you just created or generated new packages and need to wire up their dependencies, (2) user imports from a sibling package and needs to add it as a dependency, (3) you get resolution errors for workspace packages (@org/*) like "cannot find module", "failed to resolve import", "TS2307", or "cannot resolve". DO NOT patch around with tsconfig paths or manual package.json edits - use the package manager's workspace commands to fix actual linking.
