NestJS

What is NestJS?

NestJS is an open-source framework for building server-side applications, written in TypeScript. It is heavily inspired by Angular and shares similar concepts and design patterns. NestJS provides a scalable and maintainable architecture for backend applications and APIs.

Developers choose NestJS for its TypeScript support, modular setup and familiar structure — especially teams with an Angular background.

Why NestJS?

• Modularity — Code is organised into modules: cohesive units that promote reusability and separation of concerns.
• Dependency injection — Nest manages the instantiation and sharing of components, making dependencies easy to handle across the application.
• TypeScript-first — Strong typing prevents common errors and improves long-term maintainability.
• Middleware and Pipes — Intercept and process HTTP requests and responses for validation, logging and other tasks.
• WebSockets — Built-in support for real-time communication between server and clients.
• GraphQL — Native support for building GraphQL APIs alongside traditional REST endpoints.
• Server-side rendering — Integration with Angular Universal for SSR, with shared code between server and client.
• Built-in testing — A dedicated test module and utilities make unit and integration testing straightforward.

When to choose NestJS?

For teams that need a structured, well-testable backend. Particularly strong for complex APIs, microservices and applications that must remain maintainable over time.

Our approach

We typically combine NestJS with Node.js as the runtime, deploying it for the backend of larger web applications and platforms where structure and scalability are essential.
