TypeScript
TypeScript is the standard for modern JavaScript development. As a JavaScript Powerhouse, we build applications with strong types, scalable architecture and tooling that supports growth. More reliable, safer and easier to maintain.

Why choose TypeScript?
TypeScript is a superset of JavaScript that adds static typing. This allows developers to detect errors early, define clearer interfaces, and use tooling such as autocompletion and refactoring much more effectively.
Using TypeScript leads to more robust code bases, better documentation, and faster development speed in larger teams. Both front-end and back-end — from React and Vue to Node.js and NestJS — benefit from TypeScript's sleek structure and scalability.
TypeScript makes complex projects manageable and is now the standard in professional JavaScript projects.
TypeScript at Thesio: sleek, scalable and future-proof
At Thesio, TypeScript is not an option, but a default. We use it in all layers of our stack: front-end, back-end, and tooling. Our projects are modular, well-defined and prepared for growth — from the first commit.
We use advanced TypeScript features such as generics, utility types, type guards and mapped types to set up our code bases smartly and robustly. In combination with ESLint, Prettier, CI/CD type checks and clear type interfaces, we provide code that is reliable and easily transferable.
We are also ready to migrate existing JavaScript projects to TypeScript — in phases, without risks and with clear added value.
The backbone of modern JavaScript architecture
In a world where digital products are constantly growing in size, TypeScript is essential. It provides structure, prevents bugs, and accelerates collaboration. From small modules to large monorepos — with TypeScript, you lay a solid foundation for sustainable software development.
We help you get the most out of TypeScript: smartly designed, perfectly integrated and always with a focus on scalability and maintainability.
Frequently asked questions about TypeScript development
TypeScript adds types to JavaScript, which helps detect errors earlier and allows for better tooling. This makes your code more reliable, easier to maintain, and scalable for larger teams or projects.
Yes. We supervise migrations from JS to TS in a phased and controlled manner. We start with types for the most important interfaces, carry out technical audits and set up tooling and build pipelines properly to switch without risk.
Absolutely. In combination with frameworks such as NestJS or Express, TypeScript is very suitable for back-end development. It makes APIs more predictable and prevents common bugs or data differences between client and server.
Modern proven technology
We know better than anyone which technology is logical to choose in each specific situation. We are happy to share this knowledge of technology and tools.
