Recently, the Next.jsConf2023 conference showcased a groundbreaking feature called "ServerActions," which allows developers to execute SQL statements directly in their frontend code, interacting with databases seamlessly.

In the latest release, Next.js 14, ServerActions has reached its stable phase, solidifying its role as a game-changer in data handling. The team behind Next.js emphasizes that ServerActions significantly enhances the developer experience when implementing data modifications.

With ServerActions, developers can define asynchronous server functions, enabling them to perform a wide range of tasks, including revalidation of cached data, redirection to different routes, and setting and reading cookies.

In an era where the separation of frontend and backend has become prevalent,Next.js's ServerActions feature has sparked a wave of discussions, with some expressing strong disapproval.

Advantages of ServerActions

• Streamlined Data Handling: ServerActions eliminates the need for separate APIs or complex data fetching mechanisms, simplifying data management within a single codebase.
• Enhanced Developer Experience: By executing SQL statements directly from the frontend code, developers can quickly and efficiently perform CRUD (Create, Read, Update, Delete) operations, reducing the time and effort required for data manipulation.
• Improved Performance: ServerActions leverages server-side rendering (SSR) to execute database queries and handle data mutations. This approach minimizes latency and improves the overall responsiveness of web applications.

Criticisms of ServerActions

• Security Concerns: Critics argue that ServerActions may introduce security vulnerabilities, as it exposes database operations to the frontend code. Proper security measures must be implemented to mitigate potential risks.
• Complexity: ServerActions may add unnecessary complexity to the frontend code, especially for large-scaleapplications with complex data structures.
• Limited Use Cases: ServerActions is primarily suitable for simple data operations. For complex data manipulations or advanced database interactions, a dedicated backend or database management system may be more appropriate.

Conclusion

Next.js's ServerActions feature introduces a new paradigm in data management, offering both benefits and potential drawbacks. While it streamlines data handling and enhances the developer experience, it also requires careful consideration of security and complexity factors. As the technology matures and best practices emerge, ServerActions has the potential to revolutionize the development of data-intensive web applications.

鸿蒙系统开发用什么编程语言？

关于鸿蒙应用开发用什么编程语言如下：

HarmonyOS提供了支持多种开发语言的API，支持的开发语言包括ArkTS、JS(JavaScript)、C/C++、Java。

华为鸿蒙系统的简介：

华为鸿蒙系统（HUAWEI Harmony OS），是华为公司在2019年8月9日于东莞举行的华为开发者大会（HDC.2019）上正式发布的操作系统。

华为鸿蒙系统是一款全新的面向全场景的分布式操作系统，创造一个超级虚拟终端互联的世界，将人、设备、场景有机地联系在一起，将消费者在全场景生活中接触的多种智能终端，实现极速发现、极速连接、硬件互助、资源共享，用合适的设备提供场景体验。

鸿蒙OS1.0：

2019年8月9日，华为在东莞举行华为开发者大会，正式发布操作系统鸿蒙OS。鸿蒙OS是一款全场景分布式OS，可按需扩展，实现更广泛的系统安全，主要用于物联网，特点是低时延。鸿蒙OS实现模块化耦合，对应不同设备可弹性部署，鸿蒙OS有三层架构，第一层是内核。

第二层是基础服务，第三层是程序框架。2019年8月10日，荣耀正式发布荣耀智慧屏、荣耀智慧屏Pro，搭载鸿蒙操作系统。它的诞生拉开永久性改变操作系统全球格局的序幕。

鸿蒙OS2.0：

HarmonyOS2.0是华为基于开源项目OpenHarmony2.0开发的面向多种全场景智能设备的商用版本。2020年9月10日，华为鸿蒙系统升级至华为鸿蒙系统2.0版本，在关键的分布式软总线、分布式数据管理、分布式安全等分布式能力上进行了全面升级。

为开发者提供了完整的分布式设备与应用开发生态。2020年，华为已与美的、九阳、老板等家电厂商达成合作，这些品牌将发布搭载鸿蒙操作系统的全新家电产品。

学网页前台需要学SQL吗？ JS呢？

怎么说呢，如果你是纯粹 的 只是做界面，只要会pw 或者说ps 做图片处理和界面设计，以及 html 和css就可以了 ，这就是纯粹的做界面，什么都不管当然一般情况 下 都不会 只有这些工作，做前端有时也要负责 数据交互，动态html所以sql 还是要学的，js不用说，必须学的，不会js的 前端开发者不算一个合格的开发者，js 浏览器端脚本语言，是动态网页的精髓，网站的很多特效和 一些 良好的体验性都是 通过js 实现的。 举个简单的例子，网站图片轮播。 这些都是需要做前端的 人做的，不可能交给做后台的人做
