The product will evolve for years
Features are added all the time, and each new change must not break flows that already work.
TypeScript
Microsoft's superset of JavaScript that adds static typing. We choose it when the product is long-term and a bug in production is costly.
WHY WE CHOOSE THIS
In a large JavaScript project, one edit can quietly break another part of the system. TypeScript checks the links in the code before release, so the developer sees the error, not your customer.
The code will pass between teams
The project will be handed to other developers, who need to quickly understand how it all works.
A bug costs money
A failure in payments, a client area or a CRM integration hits revenue and customer trust directly.
Web apps and client areas
Typed components and data in React and Next.js, so the interface doesn't break after changes.
Node.js backend and APIs
Shared types for server and front end, so both sides understand the data the same way.
Integrations with external services
Types describe responses from payment systems, CRMs and delivery services.
React Native mobile apps
One language and one set of types for iOS, Android and the web version of the product.

Does TypeScript slow down development?+
A little at the start, not in the long run. Writing types takes time up front, but then saves hours of bug hunting and makes every next change easier.
Why TypeScript and not plain JavaScript?+
For a small website, JavaScript is enough. As the product grows, TypeScript makes the code self-documenting and catches mismatches right in the editor, so the risk of a release breaking a working feature is much lower.
Can we move an existing project to TypeScript?+
Yes, gradually. TypeScript is compatible with JavaScript, so we convert files in parts, starting with the most critical modules, and the product keeps running.
We write code for those who will maintain the product for years, not just for release.
TypeScript development at GVSPACE is the standard for products meant to last: web apps, client areas, APIs and integrations. Types make the code clear to a new team and let us find errors before a customer sees them. We use TypeScript with React, Next.js, Node.js and React Native, and move existing JavaScript projects to it gradually, without stopping the product.
