**Coursera 课程摘要：使用 Node.js、Express.js 和 Axios 构建微服务** 本课程深入探讨了微服务架构，这是一种将应用程序分解为独立、可部署服务的设计模式。与传统的单体应用不同，单体应用将所有功能紧密耦合在一起，微服务将每个功能（如电商网站中的支付、购物车、客户管理和订单处理）分离到独立的服务器和数据库中。 **主要优势：** * **松耦合与弹韧性：** 微服务架构通过松耦合的设计，提高了应用程序的弹韧性。当一个服务出现故障时，不会影响整个系统的运行。 * **独立开发与部署：** 各个服务可以独立开发、测试和部署，加快了开发周期并提高了灵活性。 * **易于维护与调试：** 开发者只需关注特定服务的功能，降低了复杂性，便于发现和修复错误。 * **提升开发者体验：** 新成员能够更快地融入项目，仅需理解自己负责的服务即可，从而提高生产力。 **技术栈：** 本课程将演示如何使用 **Node.js** 作为后端运行时环境，**Express.js** 作为简化 Node.js Web 应用开发的框架，以及 **Axios** 作为基于 Promise 的 HTTP 客户端，用于服务之间的通信。 **核心实践：** 课程将通过一个电商网站的实例，展示如何构建独立的微服务，并利用 **REST API** 框架实现它们之间的交互。学生将学习如何使用这些技术构建可扩展、可维护的分布式应用程序。
In a microservice, each software application feature is separated from the other, in most cases with their respective servers and databases. Applications built with this kind of architecture are loosely coupled, also referred to as distributed applications.Early on in the practice of software development, best practice involved tightly coupling all of the software's components in what is known as a monolithic application. However, monolithic applications require extra effort to respond to changes in the system. If any particular component develops a fault, the entire system is affected.Nowadays, we can solve the problem using microservices, which allow us to build our software product components separately. If there is a fault in one component, it won't affect the functioning of the entire software product.In this article, we'll review the concept of microservices, learn how to implement a microservice with Node.js, and explore how microservices are changing the practice of software developmentImagine we're building an ecommerce store. We'll need models for a payment feature, cart, customers, admin, and order. Each of these features will have its own separate servers and databases.Our ecommerce microservices will communicate with each other using the REST API framework. With our store features developed independently from each other, we can easily identify which feature to debug if our system develops a fault and avoid having to bring down the entire application.microservices offer a better developer experience. A new developer joining the team won't have to understand the entire code base, but rather only the features they are working on, increasing productivity.
