TypeScript

Why TypeScript Became Essential

JavaScript's dynamic nature provides flexibility on small projects but inevitably becomes a source of hard-to-find bugs in large teams. TypeScript is a superset developed by Microsoft that adds a static type system on top of JavaScript. Every JavaScript file is valid TypeScript - making gradual adoption in existing projects straightforward.

At Detartech, TypeScript has become not just a preference but a standard requirement. As the codebase grows, type annotations act as "living documentation": you no longer need to dig into source code to understand what a function accepts and returns.

How We Use TypeScript in Our Projects

We create end-to-end type safety across Next.js, React, Node.js, and .NET back-end integrations with TypeScript. We add runtime validation with Zod for API responses, reducing the gap between compile-time types and runtime data to zero.

On large projects we keep strict mode enabled to forbid any usage and enforce a consistent code style across team members. We eliminate repetition by deriving DTOs from model definitions using utility types (Pick, Omit, Partial, Required).
