vite在项目中配置路径别名

vite 加 vue3项目中报错Cannot find module 'XXXXXX ’ or its corresponding type declarations

我们只需要在以下几个文件里面配置：

vite.config.ts:

注意这里用了node的path模块需要执行npm i --save-dev @types/node命令

import {
     defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
const path = require('path');

export default defineConfig({
    
  plugins: [vue()],
  define: {
    
    'process.env': {
    },
  },
  resolve: {
    
    // 配置路径别名
    alias: {
    
      '@': path.resolve(__dirname, './src'),
    },
  },
});

tsconfig.json：

配置baseUrl，paths

{
    
  "compilerOptions": {
    
    "target": "esnext",
    "useDefineForClassFields": true,
    "module": "esnext",
    "moduleResolution": "node",
    "strict": true,
    "jsx": "preserve",
    "sourceMap": true,
    "resolveJsonModule": true,
    "esModuleInterop": true,
    "lib": ["esnext", "dom"],
    "baseUrl": ".",
    "paths": {
    
      "@/*": ["src/*"]
    }
  },
  "include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"]
}

大工告成啦！接下来可以用@别名代表src的绝对路径
