关于vite:vite-支持optional-Chaining可选链判断运算符-和-nullishCoalescingOperator

vite 反对optional Chaining（可选链判断运算符 ?.）和 nullishCoalescingOperator (空值合并运算符 ??)

装置 babel 可选链判断运算符，空值合并运算符 兼容依赖

yarn add @babel/plugin-proposal-optional-chaining --devyarn add  @babel/plugin-proposal-nullish-coalescing-operator -dev

vite.config.ts 增加配置

import { defineConfig } from "vite";import react from "@vitejs/plugin-react";import checker from "vite-plugin-checker";import vitePluginImp from "vite-plugin-imp";import path from "path";// https://vitejs.dev/config/export default defineConfig(({ mode }) => {  return {    plugins: [      react({        babel: {          plugins: [            "@babel/plugin-proposal-optional-chaining",            "@babel/plugin-proposal-nullish-coalescing-operator",          ],        },      }),    ],  };});

vue 请应用 @vitejs/plugin-vue [未测试]
