NestJS is an incredible backend framework that allows us to build scaleable Node.js backends with very little complexity. A microservice architecture is a popular architecture that allows us to build & deploy several independent applications that communicate with each other via a chosen transport layer.
NestJS 是一个令人难以置信的后端框架，它允许我们以非常低的复杂性构建可扩展的 Node.js 后端。微服务架构是一种流行的架构，它允许我们构建和部署多个独立的应用程序，这些应用程序通过选定的传输层相互通信。

This course is designed to bridge the gap between NestJS & this microservice architecture. It goes beyond the NestJS documentation to show you how to build a real reservation booking system that accepts payments, sends email notifications, and persists data to a MongoDB database.
本课程旨在弥合 NestJS 和这种微服务架构之间的差距。它超越了 NestJS 文档，向您展示了如何构建一个真正的预订系统，该系统接受付款、发送电子邮件通知并将数据持久化到 MongoDB 数据库。

Here are just some of the few additional things you can expect to learn in this course:
以下是您可以在本课程中学到的几件其他事情中的一小部分：

• Develop a productionized Dockerfile for NestJS microservices
  为 NestJS 微服务开发生产化的 Dockerfile

• Create a monorepo & shared library for common code
  为通用代码创建 monorepo 和共享库

• Learn how to create a custom package.json & Dockerfile for each microservice
  了解如何为每个微服务创建自定义 package.json 和 Dockerfile

• Automate the build & deployment of Dockerfiles with a custom CI/CD process
  使用自定义 CI/CD 流程自动构建和部署 Dockerfile

• Connect microservices together using a TCP transport layer
  使用 TCP 传输层将微服务连接在一起

This course also includes full access to the GitHub repository so you have access to the completed project at all times & can reference this completed code. Additionally, you can post any issues or questions to the QA section & I will be happy to assist you.
本课程还包括对 GitHub 存储库的完全访问权限，因此您可以随时访问已完成的项目并可以引用此完成的代码。此外，您可以将任何问题或疑问发布到QA部分，我很乐意为您提供帮助。

By the end of this course, you will know how to build, deploy & test Nestjs Microservices so you can create any scaleable application that you can think of.
在本课程结束时，您将知道如何构建、部署和测试 Nestjs 微服务，以便您可以创建任何您能想到的可扩展应用程序。
