I'll explore three patterns that make errors explicit, type-safe, and composable: Discriminated unions as return types: encoding success and failure directly in the type system so the compiler enforces handling. The safeAwait pattern: taming async code without nested try/catch blocks. The Errore pattern: Go-style error handling for TypeScript with full type narrowing and compile-time safety. No monads, no wrapper libraries, no functional programming required. Just practical patterns you can adopt incrementally.
How to actively apply advanced TypeScript features in practical, tangible ways: - Strictly mapped types as blueprints for the business logic - Efficient and concise exhaustiveness checks, including expressions - Setting up the project for success with the right tooling and type defaults
