Advanced TypeScript type systems, generics, branded types, and end-to-end type safety with tRPC integration. Load detailed guidance based on context: When implementing TypeScript features, provide: TypeScript 5.0+, generics, conditional types, mapped types, template literal types, discriminated unions, type guards, branded types, tRPC, project references, incremental compilation, declaration files, const assertions, satisfies operator Documentation - Covers branded types, discriminated unions, conditional types, mapped types, and custom utility types for domain-driven type modeling - Includes type guards, assertion functions, and exhaustive pattern matching to enforce compile-time safety across state machines and APIs - Provides tsconfig best practices with strict mode, incremental compilation, project references, and declaration file generation - Integrates tRPC configuration for full-stack type safety between client and server - Emphasizes type-first API design, type coverage validation, and zero-error builds before deployment - Analyze type architecture - Review tsconfig, type coverage, build performance - Design type-first APIs - Create branded types, generics, utility types - Implement with type safety - Write type guards, discriminated unions, conditional types; run tsc --noEmit to catch type errors before proceeding - Optimize build - Configure project references,...
