How does ssr is happening if I have used "use client" in a tsx file?

问题

我刚刚开始使用nextJS 13.4.12,目前正在将一个项目从React迁移到nextJS。在处理登录页面时,我发现nextJS不允许在服务器端组件上使用react-hook-form@hookform/resolvers/yup。为了让它们工作,你需要在组件的顶部添加use client。我也这样做了。

但令我惊讶的是,当我查看网络请求时,我仍然可以看到基本的HTML代码,包括输入框、按钮和其他一些标签。这里是如何进行服务器端渲染的?

PS:我看过很多文章、教程、片段和文档。它们直接使用hook-form和yupresolver,而没有实际指定use client。尽管它们大多使用的是13.0.5版本。

以下是我的代码:

// React Imports
'use client';
import Link from 'next/link';
import { useForm, Controller } from 'react-hook-form';
import './login.css';
import Image from 'next/image';
// Resolvers & Schema
import { yupResolver } from '@hookform/resolvers/yup';
import { signupSchema } from '@/schema/auth';
// Others
import { headerNameLogo } from '@/EntryFile/imagePath';
import Head from 'next/head';

export default function Login() {
    const {
        handleSubmit,
        control,
        setError,
        clearErrors,
        formState: { errors, isValid },
    } = useForm({
        mode: 'onChange',
        resolver: yupResolver(signupSchema),
    });

    return (

I have just started working on nextJS 13.4.12 and currently shifting a project from react to nextJS. While working on the login page I found that nextJS does not allow to use react-hook-form or @hookform/resolvers/yup on server-side components. For them to work you need to add use client at the very top of the component. And I also did that.

But to my surprise when I see the network request I can still see the basic HTML code consisting of input, buttons, and some other tags as well.
How does ssr happening here?

PS: I have seen a ton of articles, tutorials, snippets, and docs. They were directly using hook-form, yupresolver without actually specifying use client. Although they were mostly using 13.0.5.
如果在一个.tsx文件中使用了”use client”,那么ssr是如何发生的?

这是因为在最新版本的Next.js中,每个组件都会首先在服务器端进行渲染,而不管你使用了什么指令。请参考这里了解更多信息。

英文:

It is because in latest version of nextJS each component is firstly rendered on the server side, irrespective of directive you've used. Please refer here for more.
