TypeScript
At Detartech we use TypeScript across all new projects. Type safety, intra-team contracts, and IDE support raise both development speed and code quality simultaneously.
Features
- Static type checking
- Advanced IDE autocomplete
- Safe refactoring
- Strict mode and ESLint integration
- Reusable types with generics
- Full backwards compatibility with JavaScript
Use Cases
- Large-scale web applications
- Multi-developer team projects
- API client and server integrations
- Long-lived projects that need to stay maintainable
Deep Dive
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).
