Comprehensive Next.js, React, Redux, and TypeScript development guidelines covering SOLID principles, component architecture, and best practices.
Best practices and guidelines for TypeScript (2025-2026 Edition), focusing on TS 5.x+, modern type safety, and performance.
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.

Complete E2E (end-to-end) and integration testing skill for TypeScript/NestJS projects using Jest, real infrastructure via Docker, and GWT pattern. ALWAYS use this skill when user needs to: **SETUP** - Initialize or configure E2E testing infrastructure: - Set up E2E testing for a new project - Configure docker-compose for testing (Kafka, PostgreSQL, MongoDB, Redis) - Create jest-e2e.config.ts or E2E Jest configuration - Set up test helpers for database, Kafka, or Redis - Configure .env.e2e environment variables - Create test/e2e directory structure **WRITE** - Create or add E2E/integration tests: - Write, create, add, or generate e2e tests or integration tests - Test API endpoints, workflows, or complete features end-to-end - Test with real databases, message brokers, or external services - Test Kafka consumers/producers, event-driven workflows - Working on any file ending in .e2e-spec.ts or in test/e2e/ directory - Use GWT (Given-When-Then) pattern for tests **REVIEW** - Audit or evaluate E2E tests: - Review existing E2E tests for quality - Check test isolation and cleanup patterns - Audit GWT pattern compliance - Evaluate assertion quality and specificity - Check for anti-patterns (multiple WHEN actions, conditional assertions) **RUN** - Execute or analyze E2E test results: - Run E2E tests - Start/stop Docker infrastructure for testing - Analyze E2E test results - Verify Docker services are healthy - Interpret test output and failures **DEBUG** - Fix failing or flaky E2E tests: - Fix failing E2E tests - Debug flaky tests or test isolation issues - Troubleshoot connection errors (database, Kafka, Redis) - Fix timeout issues or async operation failures - Diagnose race conditions or state leakage - Debug Kafka message consumption issues **OPTIMIZE** - Improve E2E test performance: - Speed up slow E2E tests - Optimize Docker infrastructure startup - Replace fixed waits with smart polling - Reduce beforeEach cleanup time - Improve test parallelization where safe Keywords: e2e, end-to-end, integration test, e2e-spec.ts, test/e2e, Jest, supertest, NestJS, Kafka, Redpanda, PostgreSQL, MongoDB, Redis, docker-compose, GWT pattern, Given-When-Then, real infrastructure, test isolation, flaky test, MSW, nock, waitForMessages, fix e2e, debug e2e, run e2e, review e2e, optimize e2e, setup e2e
Modern TypeScript project architecture guide for 2025. Use when creating new TS projects, setting up configurations, or designing project structure. Covers tech stack selection, layered architecture, and best practices.
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
Эксперт по TypeScript. Используй для типизации, дженериков, декораторов, паттернов проектирования и best practices в TypeScript.
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...
Core TypeScript conventions for type safety, inference, and clean code. Use when writing TypeScript, reviewing TypeScript code, creating interfaces/types, or when the user asks about TypeScript patterns, conventions, or best practices.
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.
This skill should be used when the user asks to "write TypeScript code", "format TypeScript", "follow TypeScript style guide", "TypeScript best practices", or needs guidance on Google's TypeScript coding conventions.
