TypeScript Core

Comprehensive guidance for TypeScript development with strict type safety, functional patterns, and modern tooling.

Core Principles

Follow these fundamental principles in all TypeScript work:

1. TypeScript Only (Strict Mode) - Always enable strict mode and all type-checking flags
2. Simplicity First (KISS + YAGNI) - Do the simplest thing that works, avoid speculative architecture
3. Type Safety - Use Result/Effect types instead of throwing exceptions
4. Functional Patterns - Prefer composition, immutability, and pure functions
5. User Experience First - Clear error messages, predictable behavior

See principles.md for detailed guidance.
