简介
Modern, powerful web application framework for Node.js.
Nest是一套现代化的基于Node.js的强大的Web应用框架
Nest is a powerful web framework for Node.js which helps you effortlessly build efficient, scalable applications. Nest uses modern JavaScript, is built with TypeScript, and combines best concepts of both OOP (Object Oriented Progamming) and FP (Functional Programming).
Nest是一套基于Node.js的强大的Web框架，可帮助你轻松构建出高效的、可扩展的应用程序。它是通过结合OOP（面向对象编程）和FP（函数式编程）的最佳理念，采用现代化JavaScript，使用TypeScript构建的。
Nest is not just a framework. You don’t have to wait for a large community because Nest is built with awesome, popular, well-known libraries—Express and socket.io (you can use any other library if you want to)! It means, that you could quickly start using framework without worrying about a third party plugins.
Nest不仅仅只是一套框架，因为它是基于绝妙的，著名的流行库Express和Socket.io构建的（你也可以根据自己的需求选择任何其他库），所以无需等待大型社区，可以直接使用，无需担心第三方库的缺失。

理念
JavaScript is awesome. This language is no longer just trash to create simple animations in the browser. Now, the front end world sports a rich variety of tools. We have a lot of amazing frameworks / libraries such as Angular, React or Vue, which improve our development process and make our applications fast and flexible.
Javascript是一门非常神奇的计算机语言。它不再是一门只能在浏览器上创建简单动画的语言。现在，前端领域已经开发出了多种绝妙的高性能的框架/库，例如Angular、React 和 Vue, 这些工具大大地提高了我们的开发进程，并且使我们的应用程序变得快速而灵活。
Node.js enabled us to use JavaScript also on the server side. There are a lot of superb libraries, helpers and tools for node, but none of them solves the main problem—the architecture.
通过Node.Js，我们可以在服务器端使用JavaScript。虽然现在有很多基于Node的库、助手和工具，但是没有任何一个可以解决主要问题-结构体系问题。
We want to create scalable, loosely-coupled, easy-to-maintain applications. Let’s show the entire world the potential of node.js together!
我们希望创建出可扩展的、松散耦合的、易于维护的应用程序。让我们一起来看看Node.js的潜能吧！
特点
- Easy to learn - syntax is similar to Angular
- Built on top of TypeScript, but also compatible with plain ES6 (I strongly recommend to use TypeScript)
- Based on well-known libraries (Express / socket.io) so you could share your experience
- Supremely useful Dependency Injection, built-in Inversion of Control container
- Hierarchical injector - increase abstraction in your application by creating reusable, loosely coupled modules with type injection
- WebSockets module (based on socket.io, although you can use any other library using adapter)
- Own modularity system (split your system into reusable modules)
- Reactive microservices support with messages patterns (built-in transport via TCP / Redis, but you can use any other type of communication using CustomTransportStrategy)
- Exceptions handler layer, exception filters, sync & async pipes layer
- Testing utilities
- 便于学习-语法结构类似Angular。
- 基于TypeScript构建，同时兼容普通的ES6（强烈建议使用TypeScript).
- 基于著名的（Express/Scoket.io)库，所以可以分享经验。
- 非常有用的依赖注入，内置控制反转容器。
- 分层注入器器—通过使用类型注入创建可重用、松耦合的模块，从而在应用程序中增加抽象性。
- WebScokets模块（基于scoket.io，虽然你可以使用任何其他使用适配器的库。
- 独特的模块化系统（将你的系统分割成克重用的模块）。
- 消息类型支持的反应微服务（内置transport属性，决定使用TCP或者Redis，但是你可以选择使用任何其他使用CustomTransportStrategy的交流形式）。
- 异常处理layer，异常过滤器，同步和异步pipes layer。
- 测试工具
