# NestJS

NestJS is the TypeScript backend framework we use to build robust, modular server-side applications and APIs with a familiar, Angular-inspired structure.

## 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.
