TypeScript Production Patterns

Robust TypeScript error handling uses custom error classes and Result types for predictable error management. This approach enforces type safety by making error states explicit in your function signatures, preventing unhandled runtime exceptions.

Branded types are advanced TypeScript patterns that create nominally typed primitives from structural types. Use branded types to prevent mixing semantically different values like UserId and OrderId at compile time, ensuring strict type safety.

Type API responses using discriminated unions to represent success, error, and paginated data states. This TypeScript pattern enforces type safety by requiring exhaustive type checking before accessing response properties.

Yes, these TypeScript production patterns include database type safety with Prisma. They provide patterns to enforce strict end-to-end type checking from your database queries to your API responses.

The best way to configure TypeScript for production is enabling strict type checking by setting "strict": true in your tsconfig.json. This rigorous configuration prevents runtime errors and maintainable code.

Conditional types and utility types allow you to build expressive, safe code for API response typing in backend services. They dynamically derive types from existing data structures, reducing manual type duplication.
