前置条件请先完成《从零搭建一个 AI 猜字游戏后端》并在 Swagger UI 中确认所有后端接口测试的 API 接口。

常见开发痛点

• 痛点一：依赖建立工具导致项目启动慢、调试麻烦。不过，
• 痛点二：SSE 流式数据难以处理。手写 ReadableStream 很容易出错。
• 痛点三：聊天 UI 开发中常见的自动滚动、输入框状态同步等细节实现繁琐。
• 痛点四：状态管理与模板绑定容易出现脏读或无响应更新。

先看最终效果

浏览器打开后你会看到：

• 左侧是会话列表。可新建、切换、删除对话
• 中间是聊天区，输入消息后 AI 会逐字“吐”出回复
• 右侧是游戏规则说明
• AI 正在回复时显示“对方正在输入…”跳动动画

HTML 最小骨架

页面骨架已就绪

* 在浏览器直接使用 ESM 可省去 npm 与打包流程，极大缩短启动时间。

CSS 最小样式

/* 基础重置 */
至于*。*:，before,*::after{margin:0;padding:0，border-box:border-box;}
html{font-family:'Microsoft YaHei',sans-serif;font-size:14px;background:#f0f2f5;}
/* Flex 三栏容器 */
.app-main{display:flex;height:calc);overflow:hidden;说起来，}
.sidebar-left。.sidebar-right{background:#fff;border-right:1px solid #e5e7eb;}
.chat-area{flex:1;background:#f0f2f5;其实，} /* 中间区域占满剩余空间 */
.chat-messages{flex:1;padding:20px;margin-bottom:-10px;}
/* 简单主题变量示例 */
:root{--primary:#4a6cf7;}
`css` 是可选项，主要是利用 `flex` 实现自适应三栏布局。

* 使用 CSS Variables 可以一处改动即可统一全局主题色。

JS 最小验证
// 导入 Vue
import { createApp,ref } from 'vue';createApp({
setup{
const message = ref;return {message};}
}).mount，不过，

* 如果页面显示 “Vue 已挂载成功！”，说明 ESM 与 ImportMap 配置无误。可继续往下做功能实现，

🧭 第二关：完成完整三栏布局与交互指令绑定

This is a placeholder for your custom logo and navigation bar.
Use this space to add your own branding or any or elements you want.
If you’re building an app with multiple pages or sections,you can replace this placeholder with a dynamic navigation menu that changes based on current page or section.
This is a great way to keep your header consistent across all pages while still giving each page its own unique look and feel.
Here’s how you can do it:


- Add a new component called HeaderComponent.vue that contains header layout and logic.

- In each page component。import HeaderComponent and include it in template.

- Use props or Vue Router’s current route information to control which parts of header should be visible on each page.
This way you can keep your code DRY and maintain a consistent header across different pages while also allowing each page to have its own unique layout.
It could be quite easy if we are building simple single-page application that only has one page but if you want more complex structure,best practice would be to separate out components into ir own files so you can reuse m across pages.
When using vue-router,we can create multiple routes in router/index.js file,and set up different views for each route using lazy loading.
Then we can use dynamic imports to load only necessary components when needed,which improves performance and keeps our code organized.
Finally we can wrap everything into an App.vue component that serves as root for our application.
You might also want to think about how users navigate through your app – do y go from one page to anor?话说回来，Do y open modal dialogs?Or maybe y use tabs?In all cases we’ll probably want some kind of global state store or provide/inject pattern so that shared data stays consistent across components.
Now let’s go ahead and start implementing our header component – it will be reusable across all pages,and allow us flexibility for adding new features later on without messing up existing ones.
Here are some good things about this approach:


- Easy maintenance – just update HeaderComponent once and everything changes at once.

- Reusability – components are self‑contained pieces of UI that can be used wherever needed.

- Testability – smaller units mean easier unit tests with Jest or Vitest.
• If you’re new to vue‑in‑components re are many resources available online where people share templates。and se guides help me understand how best practice works.
Once you’re comfortable with how vue‑in‑components approach works in practice –
you will get 娱乐ter at thinking about patterns in terms of reusability.
So let’s start building a reusable component – it will contain everything…For now lets go ahead…We’ll have many small components but y will be easier for us as well as or devs who work on m too!The key idea is simple – reuse instead of copy-paste
So let’s write code…Here’s some more details…We’ll write an AppBar.vue which contains top level layout with logo…We will add some icons for quick access…It would also contain some buttons for toggling dark mode…The icon names mselves look very cool.
One more thing—some icons may look like weird shapes?But it should look good overall!It would help us get what we need!Now we know what needs…Ok i’m going to put this here now …In short I’ve written most of basic stuff already…If any furr info is needed please contact me :)
Also see below example usage.. It just shows how I set up my own build system.. It uses Vite…But re are or ways too …To run locally just do something similar …说起来，After reading over my design ideas I have decided I’ll write something simpler…Because I don’t think anyone wants such complex structure.
Anyway i hope this helps!Some or tips:

Let me know if i made any mistakes — thanks!a>
