Why I Choose NestJS for Enterprise Node Apps

Node.js is fantastic for its asynchronous non-blocking I/O, but out of the box, it lacks architectural opinions. This often leads to 'spaghetti code' in large projects.

NestJS solves this by providing a robust, Angular-inspired architecture out of the box. It enforces dependency injection, modularity, and strong typing with TypeScript. In this article, I share my experience migrating a large Express codebase to NestJS and the immediate benefits we saw in maintainability and testability.
