在Vue+Ts+Vite项目中配置别名指向不同的目录并引用的案例详解

import { defineConfig, AliasOptions } from 'vite';
import vue from '@vitejs/plugin-vue';
import path from 'path';
//vue3+vite+ts 配置@时vscode报找不到__dirname的问题：
//报错原因：path 模块是 node.js 的内置模块，而 node.js 默认不支持 ts 文件的
//解决：安装 @type/node 依赖包 npm install @types/node --save-dev 或 cnpm i @types/node --save-dev、pnpm i @types/node --save-dev
export default defineConfig({
  plugins: [vue()],
  resolve: {
    // 这里配置需要注意：Vite新版本resolve配置改为对象形式，如下：
    alias: [
      {
        find: '@',
        replacement: path.resolve(__dirname, 'src')
      },
      {
        find: 'pub',
        replacement: path.resolve(__dirname, 'public/')
      },
      {
        find: 'comps',
        replacement: path.resolve(__dirname, 'src/components')
      },
      {
        find: 'apis',
        replacement: path.resolve(__dirname, 'src/apis')
      },
      {
        find: 'views',
        replacement: path.resolve(__dirname, 'src/views')
      },
      {
        find: 'routes',
        replacement: path.resolve(__dirname, 'src/router')
      },
      {
        find: 'store',
        replacement: path.resolve(__dirname, 'src/store')
      },
      {

        replacement: path.resolve(__dirname, 'src/utils')
      },
      {
        find: 'styles',
        replacement: path.resolve(__dirname, 'src/styles')
      },
      {

      },
      {

      {

// 引入public文件下的json文件示例
import JsonCard from 'pub/json/Card.json';

pub代表在vite.config.ts中配置的，直接指向public目录
{
        find: 'pub',
        replacement: path.resolve(__dirname, 'public/')
},
