Dependency Injection

Nest.js leverages dependency injection to manage the flow of dependencies throughout the application. This approach promotes loose coupling between modules, improves testability, and facilitates code reuse.

Under the hood, Nest.js utilizes Express.js, a popular web framework for Node.js. This provides Nest.js with compatibility with the vast ecosystem of Express middleware and tools, while also offering the flexibility to integrate with other Express-based frameworks seamlessly.

Decorators and Metadata

Nest.js uses decorators and metadata to define and configure various components of an application, such as controllers, services, and routes. This declarative approach simplifies code structure and reduces boilerplate, leading to cleaner and more concise code.

Middleware and Interceptors

Nest.js provides middleware and interceptors for handling cross-cutting concerns, such as logging, authentication, and error handling. Middleware functions can intercept requests and responses at various stages of the request lifecycle, while interceptors can intercept method calls within the application.

WebSocket Support

Nest.js offers built-in support for WebSockets, enabling real-time bidirectional communication between clients and servers. This feature is particularly useful for building chat applications, multiplayer games, and other real-time applications.

GraphQL Integration

Nest.js seamlessly integrates with GraphQL, a query language for APIs, allowing developers to build GraphQL APIs with ease. Nest.js provides decorators and utilities for defining GraphQL schema, resolvers, and middleware.
