+
+## Example
+
+This plugin enables `@babel/parser` to parse
+
+```js
+export { smile as "😄" } from "./emojis.js";
+```
+
+It requires `@babel/parser@^7.12.0`. When used with `@babel/plugin-transform-modules-commonjs`, the example above will be transformed as
+
+```js
+const emojis = require("./emojis.js");
+Object.defineProperty(exports, "__esModule", {
+  value: true,
+});
+
+exports["😄"] = emojis.smile;
+```
+
+Note that it is not possible to transpile this syntax to ES2015-style imports and exports. They are supported in other module systems such as amd, systemjs and umd.
+
