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 --dev yarn add @babel/plugin-proposal-nullish-coalescing-operator -dev
react中：
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中：
import esbuild from 'rollup-plugin-esbuild'
export default defineConfig(
{
plugins: [
vue(),
{
...esbuild({
target: 'chrome70',
// 如有需要可以在这里加 js ts 之类的其他后缀
include: /\.vue$/,
loaders: {
'.vue': 'js',
},
}),
enforce: 'post',
},
],
)
