vue3.0+vite+ts项目搭建--vite.config.ts配置(三)

vite.config.ts配置

配置路径处理模块

安装ts的类型声明文件

yarn add @types/node -D

通过配置alias来定义路径的别名

resolve: {
    alias: {
      '@': path.resolve(__dirname, 'src'),
      '@coms': path.resolve(__dirname, 'src/components')
    }
  }

配置自动在浏览器打开

server: {
    open: true
  }

配置scss全局变量

安装依赖

npm install node-sass sass-loader sass -D

css: {
    preprocessorOptions: {
      scss: {
        additionalData: `@import "@/assets/scss/_theme.scss";`
      }
    }
  }

 vite.config.ts中虽然不对报错但是process.env参数中没有.env配置文件中的参数

配置按需加载

import styleImport from 'vite-plugin-style-import'
plugins: [
    vue(),
    styleImport({
      libs: [{
        libraryName: 'vant',
        esModule: true,
        resolveStyle: (name) => {
          return `vant/es/${name}/style/css`;
        },
      }]
    })
  ]

完整配置文件如下

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
// import styleImport from 'vite-plugin-style-import'
import importToCDN, { autoComplete } from 'vite-plugin-cdn-import'
// 路径处理模块
import path from 'path'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue(),
    // styleImport({
    //   libs: [{
    //     libraryName: 'vant',
    //     esModule: true,
    //     resolveStyle: (name) => {
    //       return `vant/es/${name}/style/css`;
    //     },
    //   }]
    // }),
    importToCDN({
      modules: [
        autoComplete('vue'),
        autoComplete('axios'),
