TypeScript Core Patterns
Modern TypeScript development patterns for type safety, runtime validation, and optimal configuration.
Quick Start
New Project: Use 2025 tsconfig → Enable strict + noUncheckedIndexedAccess → Choose Zod for validation
Existing Project: Enable strict: false initially → Fix any with unknown → Add noUncheckedIndexedAccess
API Development: Zod schemas at boundaries → z.infer<typeof Schema> for types → satisfies for routes
Library Development: Enable declaration: true → Use const type parameters → See advanced-patterns-2025.md
Quick Reference
tsconfig.json 2025 Baseline
