前言
在 NestJS 中,依赖注入是一个核心概念,用于管理应用程序的组件和服务之间的依赖关系。 这种模式通过提供一个容器(NestContainer)来解决类之间的依赖关系, 使得代码更加模块化、可测试且易于维护。
Dependency Injection system of Nest.js
Introduction
-
The Dependency Injection(DI) pattern
- is frequently used today by the bigest framework.
-
It is a way
- to keep code clean and easier to use.
-
By using this pattern
- you end up with fewer coupled components
- and more reusable ones
- which helps accelerate the development process time
-
Nest.js is based on Angular in terms of architecture
-
is used to create
- testable
- scalable
- lossely-coupled
- easily maintainable application
-
is used to create
-
As is the case with Angular
- Nest.js has ite own dependency injection system
- which is part of the core of the framework
- meaning that Nest.js is less dependent on a third-party library.
- Nest.js has ite own dependency injection system

-
依赖注入模式
- 目前最大的框架都京城使用这种模式
- 这是一种保持代码简洁、更易于使用的方法
- 使用这种模式可以减少耦合组件的数量,增加可重用组件的数量,从而加快开发进程
-
Nest.js在架构上基于Angular
- 用于创建:可测试、可扩展、松耦合和易维护的应用程序
- 与Angular一样,Nest.js也有自己的依赖注入系统
- 这是架构核心的一部分
- 这意味着Nest.js对第三方库的依赖性较低
