es6 export-from用法

2024-09-05 22:38:51

语法：

export * from "foo";

export {foo} from "foo";

export {foo, bar} from "foo";

export {foo as bar} from "foo";

export {foo as default} from "foo";

export {foo as default, bar} from "foo";

export {default} from "foo";

export {default as foo} from "foo";

注意：export-from 用于聚集模块。但不能在直接使用。例如在index.js里export { a } from 'b.js', a在index.js里无法使用
