5、搭建前端项目

5.1 使用vite + vue搭建

win + r 打开终端

切换到你想要搭建的盘

npm init vite@latest

跟着以下步骤取名即可

cd fullStackBlognpm installnpm run dev

默认在 http://localhost:5173/ 下启动了

5.2 用vscode打开项目并安装需要的插件

1、删除多余的 HelloWorld.vue 文件

2、安装需要的插件

网络请求我直接用fetch了，你需要用axios的话就执行以下命令安装，使用也很简单

npm i axios -S

安装Element-Plus并引入到入口文件 main.js （这里使用了全局引入，按需引入的参考官网，很简单）

安装element-plus/icons-vue图标

npm install @element-plus/icons-vue

全局引入

npm install element-plus --save

在main.js中引入：

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import App from './App.vue'
import * as ElementPlusIconsVue from '@element-plus/icons-vue'const app = createApp(App)app.use(ElementPlus)
for (const [key, component] of Object.entries(ElementPlusIconsVue)) {app.component(key, component)
}
app.mount('#app')

**按需引入需要装两个插件，然后在vite.config.js中配置（打开注释部分即可）：

npm install -D unplugin-vue-components unplugin-auto-import unplugin-icons

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
// import AutoImport from 'unplugin-auto-import/vite'
// import Components from 'unplugin-vue-components/vite'
// import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'
// import Icons from 'unplugin-icons/vite'
// import IconsResolver from 'unplugin-icons/resolver'// https://vitejs.dev/config/
export default defineConfig({plugins: [vue(),// AutoImport({//   resolvers: [//     ElementPlusResolver(),//     IconsResolver({//       prefix: 'Icon',//     })//   ],// }),// Components({//   resolvers: [//     ElementPlusResolver(),//     IconsResolver({//       enabledCollections: ['ep'],//     }),//   ],// }),// Icons({//   autoInstall: true,// }),],
})

安装tailwindcss并配置

执行以下命令安装tailwindcss和相应的插件

npm install -D tailwindcss postcss autoprefixer

npx tailwindcss init -p

会生成 tailwind.config.js 和 postcss.config.js 文件即可

然后在assets文件夹下创建一个 tailwind.css 文件（名称可以自定义） 写上以下代码，并引入到入口文件main.js

// tailwind.config.js

/** @type {import('tailwindcss').Config} */
export default {content: ["./index.html","./src/**/*.{vue,js,ts,jsx,tsx}",],theme: {extend: {},},plugins: [],
}

// postcss.config.js

export default {plugins: {tailwindcss: {},autoprefixer: {},},
}

// tailwind.css文件

@tailwind base;
@tailwind components;
@tailwind utilities;

// main.js

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import './assets/css/tailwind.css'
import './style.css'
import App from './App.vue'const app = createApp(App)app.use(ElementPlus)
app.mount('#app')

3、在App.vue中验证element 与 tailwind 是否生效

// App.vue

<template><div><h4 class="text-3xl font-blod underline">demo</h4><el-button class="mt-24" type="primary">button</el-button></div>
</template><script setup>
</script><style scoped>
</style>

验证没问题！

5.3 页面布局

安装vue-router路由

npm install vue-router@4

在src目录下新建router文件夹，新建index.js路由文件

// router/index.js

import { createRouter, createWebHistory } from "vue-router";const route = [{path: '/',component: () => import('../views/blog/List.vue')},{path: '/add',component: () => import('../views/blog/Add.vue')}
]const router = createRouter({history: createWebHistory(),routes: [...route]
});export default router;

在src下新建views文件夹，在views下新建blog文件夹，在blog下新建List.vue 和 Add.vue 文件

// List.vue

<template><div>list</div>
</template><script setup></script><style scoped></style>

// Add.vue

<template><div>add</div>
</template><script setup></script><style scoped></style>

在main.js中引入路由并挂载

// main.js

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import './assets/css/tailwind.css'
import './style.css'
import App from './App.vue'
import router from './router'const app = createApp(App)app.use(router)
app.use(ElementPlus)
app.mount('#app')

在components下新建Header.vue Main.vue Footer.vue Nav.vue 并添加如下代码：

// Header.vue

<template><div><el-header class="h-16 p-4 header-wrapper"><el-row><el-col :span="12"><button class="button" data-text="Awesome" @click="goToHome"><span class="actual-text">&nbsp;blog&nbsp;</span><span aria-hidden="true" class="hover-text">&nbsp;blog&nbsp;</span></button></el-col><el-col :span="12" class="flex justify-end"><Nav /></el-col></el-row></el-header></div>
</template><script setup>
import Nav from './Nav.vue'</script><style scoped>
.header-wrapper{line-height: 64px;
}
</style><style scoped>
.button {margin: 0;height: auto;background: transparent;padding: 0;border: none;cursor: pointer;
}.button {--border-right: 6px;--text-stroke-color: #1da1f2;--animation-color: #1da1f2;--fs-size: 2em;letter-spacing: 3px;text-decoration: none;font-size: var(--fs-size);font-family: "Arial";position: relative;text-transform: uppercase;color: transparent;-webkit-text-stroke: 1px var(--text-stroke-color);
}.hover-text {position: absolute;box-sizing: border-box;content: attr(data-text);color: var(--animation-color);width: 0%;inset: 0;border-right: var(--border-right) solid var(--animation-color);overflow: hidden;transition: 0.5s;-webkit-text-stroke: 1px var(--animation-color);
}.button:hover .hover-text {width: 100%;filter: drop-shadow(0 0 23px var(--animation-color))
}
</style>

// Main.vue

<template><div><el-main class="flex justify-center items-center container"><RouterView /></el-main></div>
</template><script setup></script><style scoped>
.container {min-width: 100%;height: calc(100vh - 128px);
}
</style>

// Footer.vue

<template><div><el-footer class="h-16 flex justify-center items-center bg-black text-white">Footer</el-footer></div>
</template><script setup></script><style scoped></style>

// Nav.vue

<template><div class="button-container"><button class="button" @click="goHome">List</button><button class="button" @click="goAdd">Add</button>
</div></template><script setup>
import { useRouter } from 'vue-router'const router = useRouter()const goHome = () => {router.push({ path: '/' })
}const goAdd = () => {router.push({ path: '/add' })
}
</script><style scoped>
.button-container {display: flex;background-color: rgba(0, 73, 144);width: 250px;height: 40px;align-items: center;justify-content: space-around;border-radius: 10px;box-shadow: rgba(0, 0, 0, 0.35) 0px 5px 15px,rgba(0, 73, 144, 0.5) 5px 10px 15px;transition: all 0.5s;
}
.button-container:hover {width: 300px;transition: all 0.5s;
}.button {outline: 0 !important;border: 0 !important;width: 40px;height: 40px;border-radius: 50%;background-color: transparent;display: flex;align-items: center;justify-content: center;color: #fff;transition: all ease-in-out 0.3s;cursor: pointer;
}.button:hover {transform: translateY(-3px);
}.icon {font-size: 20px;
}</style>

// App.vue改造为以下结构

<template><div><Header></Header><Main></Main><Footer></Footer></div>
</template><script setup>
import Header from './components/Header.vue'
import Main from './components/Main.vue'
import Footer from './components/Footer.vue'</script><style scoped>
</style>

初步布局完成，页面如图：

5.4 新增博客页面 （前端部分）

页面使用了markdown语法，安装以下插件：

编写markdowm：mavon-editor

展示markdown：markdown-it、highlight.js

vue2下安装mavon-editor，vue3下安装mavon-editor@next

npm install mavon-editor@next markdown-it highlight.js  --save

// Add.vue

四个字段：

​ 标题：title

​ 作者： auth

​ 文档：mdoc

​ 创建时间：createtime

// markdowm 暂时对图片没做处理

<template><div class="add-wrapper"><div class="top-anonymous"><el-input v-model="title" placeholder="标题（选填）"></el-input><el-input class="mt-4" v-model="auth" placeholder="作者（选填）"></el-input></div><div class="bottom-anonymous"><mavon-editor class="h-full" :toolbars="markdownOption" v-model="mdoc" /></div><button class="mt-8 button_submit" @click="save"><div class="button_submit__int"><span class="button_submit__span">Submit</span></div></button></div>
