The progress of Vue3 over Vue2: better server-side isomorphism

Vue3’s progress over Vue2: Better server-side isomorphism

Vue.js is a popular JavaScript framework for building user interfaces. In recent years, Vue.js has been loved by developers for its simplicity, ease of use and flexibility. Vue2, as the previous version, has achieved great success during the development process. However, as front-end demands increase and requirements for performance and maintainability continue to increase, Vue3 emerged as the times require and brings many new features and improvements.

In Vue3, one of the most important improvements is better server-side isomorphism support. Server-side isomorphism refers to rendering a Vue application both on the server side and on the client side. This approach provides a better user experience, as well as better search engine optimization. Implementing server-side isomorphism in Vue2 had some challenges, but in Vue3, it becomes much simpler.

The following is a sample code for server-side isomorphism using Vue3:

// 创建Vue实例 import { createApp } from 'vue' import App from './App.vue' // 创建服务器端渲染实例 import { createSSRApp, renderToString } from '@vue/server-renderer' const app = createApp(App) // 将Vue实例转换为服务器端渲染实例 const ssrApp = createSSRApp(app) // 渲染Vue应用程序 // 这里假设请求的路径是'/' export default async function (req, res, next) { const html = await renderToString(ssrApp, { url: req.url }) res.send(html) }

In the above code, we first create a Vue instance using thecreateAppfunction, and then use ThecreateSSRAppfunction converts a Vue instance into a server-side rendering instance.

In the request processing function, we use therenderToStringfunction to render the server-side rendering instance into an HTML string, and send the HTML string through theres.sendmethod to the client.

Through the above code examples, we can see that Vue3 has greatly improved server-side isomorphism compared to Vue2. In addition to simpler code writing and better performance, Vue3 also provides more server-side rendering functions, allowing us to handle the server-side rendering process more flexibly.

To sum up, the progress of Vue3 in terms of server-side isomorphism compared to Vue2 is obvious. It makes it easier for developers to implement server-side rendering and leads to better user experience and search engine optimization. As Vue3 continues to develop and optimize, we can expect more improvements and innovations in server-side isomorphism.
