Vue3+TS+Element-plus浅用

一、创建项目使用(vue create)

vue create hello-world

vue create.png

二、项目中引入TS

vue add typescript

vue add typescript.png

安装前会验证几个问题，如下:

? Use class-style component syntax? (Y/n)  //y
是否使用Class风格装饰器？选择Y
? Use Babel alongside TypeScript (required for modern mode, auto-detected polyfills, transpiling JSX)?
使用Babel与TypeScript一起用于自动检测的填充? yes
? Convert all .js files to .ts? (Y/n) //n
是否要把所有js文件转换成ts文件，这里最好选n
? Allow .js files to be compiled? (y/N) //Y
是否允许.js文件的编译，这里肯定是Y
? Skip type checking of all declaration files (recommended for apps)? (Y/n)  //Y
是否跳过所有类型检查,默认选Y

三、安装Element-plus

vue add element-plus

安装完自动配置到main.js中。然后开始整，element-plus组件随便选一个带TS的即可

<template>
  <div class="demo-image__preview">
    <el-image
      style="width: 100px; height: 100px"
      :src="url"
      :preview-src-list="srcList"
      :initial-index="4"
      fit="cover"
    />
  </div>
</template>

<script lang="ts" setup>
const url =
  'https://fuss10.elemecdn.com/a/3f/3302e58f9a181d2509f3dc0fa68b0jpeg.jpeg'
const srcList = [
  'https://fuss10.elemecdn.com/a/3f/3302e58f9a181d2509f3dc0fa68b0jpeg.jpeg',
  'https://fuss10.elemecdn.com/1/34/19aa98b1fcb2781c4fba33d850549jpeg.jpeg',

]
</script>

<style scoped>
.demo-image__error .image-slot {
  font-size: 30px;
}
.demo-image__error .image-slot .el-icon {
  font-size: 30px;
}
.demo-image__error .el-image {
