Node.js and TypeScript development

Node.js with TypeScript is our default choice for products that change often: a single language across the stack, types shared between server and interface, and a mature ecosystem for integrations.

What we build on Node.js

• APIs for web and mobile applications, with authentication, rate limiting and OpenAPI documentation.

• Full-stack applications on Next.js, server-rendered for SEO and mobile speed.

• Real-time services: notifications, live tracking, collaborative editing.

• Integration services that sit between systems and translate data formats.

• Background processing: large imports, document generation, overnight synchronisation.

Why TypeScript rather than JavaScript

Types are not bureaucracy; they are documentation that cannot go stale. In a project that passes through several hands, TypeScript catches at compile time exactly the class of error that otherwise reaches production: renamed fields, missing values, API contracts changed without notice.

Performance and limits

Node.js is excellent for I/O-heavy work and weak for CPU-bound computation. When a project needs heavy data processing or statistical models, we move that part to Python or .NET and keep Node.js for the API layer.

Delivery

We ship containerised, with a continuous integration pipeline, versioned database migrations and monitoring configured before launch rather than after the first incident.
