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

})

main.js主入口

import { createApp } from 'vue'
import App from './App.vue'

// 引入Router和Store
import Router from './router'
import Store from './store'

// 引入插件配置
import Plugins from './plugins'

const app = createApp(App)

app
.use(Router)
.use(Store)
.use(Plugins)
.mount('#app')

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 -->
		<Main />
	</div>
</div>

<template>
	<div class="vegpt__editor">
