使用vue3+pinia2开发仿制chatgpt界面聊天实例Vue3-Chatgpt
基于Vue3.x+Pinia2+VueRouter+Vue3-Markdown等技术构建仿ChatGPT网页端聊天程序。支持经典+分栏界面布局、light/dark模式、全屏+半屏显示、Markdown语法解析、侧边栏隐藏等功能。
技术框架
- 编辑工具：Cursor
- 框架技术：Vue3+Vite4.x+Pinia2
- 组件库：VEPlus (基于vue3桌面端组件库)
- 国际化多语言：vue-i18n^9.2.2
- 代码高亮：highlight.js^11.7.0
- 本地存储：pinia-plugin-persistedstate^3.1.0
- markdown解析：vue3-markdown-it

vue3.x组件库
项目中使用的组件库是基于vue3自定义UI组件库Ve-plus。一个支持40+组件的轻量级组件库。
安装组件
yarn add ve-plus
npm i ve-plus --save

整体布局
项目支持2种布局模式，整体分为顶栏+侧边栏+主体内容三大模块构成。
<div class="ve__layout-body flex1 flexbox">
<!-- //中间栏 -->
<div class="ve__layout-menus flexbox" :class="{'hidden': store.config.collapse}">
<aside class="ve__layout-aside flexbox flex-col">
<ChatNew />
<Scrollbar class="flex1" autohide size="4" gap="1">
<ChatList />
</Scrollbar>
<ExtraLink />
<Collapse />
</aside>
</div>
<!-- //右边栏 -->
<div class="ve__layout-main flex1 flexbox flex-col">
<!-- 主内容区 -->
