What is NestJS?
NestJS is a development framework based on Node.js, built with TypeScript, used to create efficient, reliable, and scalable server-side applications. It adopts a modular architecture design, combining elements of object-oriented programming, functional programming, and reactive programming.How to use NestJS?
NestJS can be installed via npm or yarn and provides a rich set of command-line tools to create and manage projects. Developers can quickly set up the project structure and define components such as controllers and services through decorators.Applicable scenarios
NestJS is very suitable for building enterprise-level backend services, microservice architectures, real-time applications, and RESTful APIs. It is also widely used in the backend part of full-stack development.Main features
Modular architectureUse modules (@Module) to organize application code, achieving high modularity and maintainability
Dependency injectionBuilt-in powerful dependency injection system, making it easier to decouple and test components
Multi-transport layer supportSupports multiple communication protocols such as HTTP, WebSockets, gRPC, and MQTT
TypeScript supportCompletely built with TypeScript, providing excellent type checking and development experience
Advantages and limitations
Advantages
Out-of-the-box application architecture, reducing project setup time
Syntax and patterns similar to Angular, reducing the learning curve
Rich ecosystem and active community support
Good documentation and sample code
Supports microservice architectures and integration with multiple databases
Limitations
May seem overly heavyweight for small projects
TypeScript is required and does not directly support pure JavaScript development
Slightly lower performance compared to lightweight frameworks such as Express
Requires understanding of concepts such as decorators and dependency injection
How to use
