Top-level await 新特性(ERROR: Top-level await is not available in the configured target environment (“chrome87”.....})
Top-level await 新特性
「ECMAScript」提案 Top-level await 由 Myles Borins 提出,它可以让你在模块的最高层中使用 await 操作符。在这之前,你只能通过在 async 函数或 async generators 中使用 await 操作符。Top-level await 是个新特性,打包不支持此特性
所以在js文件中直接写await,在打包时会报错:
Top-level await is not available in the configured target environment, “edge88”, “es2019”, “firefox78”, “safari13.1”)
解决方法:
1.引入vite-plugin-top-level-await
npm install vite-plugin-top-level-await -D
2.在vite.config.js配置此插件
import topLevelAwait from 'vite-plugin-top-level-await' export default defineConfig({ plugins: [ topLevelAwait({ // The export name of top-level await promise for each chunk module promiseExportName: '__tla', // The function to generate import names of top-level await promise in each chunk module promiseImportName: i => `__tla_${i}` }) ] });
