Rewrite the title as: How to pass data from Node.js using SSR in Vue 3

Question

I'm building a website using vue.js3 and I want to use server side rendering. I also want to be able to pass data to vue.js3 from my fastify (or express) server. Is there a way I can do this (I saw something called express-vue: github link, but it's for vue2 and not official, so I don't know if it's any good)? And can you include the hydration of the client as I saw some examples like https://github.com/mod

You can translate the above content into Chinese:

您可以将上下文对象传递给renderToString函数
const context = { data: 'Hello world' } // 您想要共享的数据
const html = renderToString(App, context)

在Vue组件中，可以使用useSSRContext来访问此对象
setup() {
    if (typeof window === 'undefined') {
        const context = useSSRContext()
        console.log(context.data) // Hello world
    }
}

与Vue 2不同，您无需在
中添加data-server-rendered="true"，当您在浏览器上使用createSSRApp而不是createApp时，Vue 3会自动进行客户端渲染

要在浏览器中传递对象，您需要在从服务器返回结果时将其写入中的window变量中
const html = renderToString(App, context)

res.send(`
    
    
        
    
        ${html}
        
    
`)
