+# @babel/plugin-transform-modules-systemjs
+
+> This plugin transforms ES2015 modules to [SystemJS](https://github.com/systemjs/systemjs).
+
+## Example
+
+**In**
+
+```javascript
+export default 42;
+```
+
+**Out**
+
+```javascript
+System.register([], function (_export, _context) {
+ return {
+ setters: [],
+ execute: function () {
+ _export("default", 42);
+ }
+ };
+});
+```
+
+For dynamic import support (`import('./lazy.js').then(m => ...)`), enable the [@babel/plugin-syntax-dynamic-import](https://babeljs.io/docs/plugins/syntax-dynamic-import/) plugin before this one.
+
+## Installation
+
+```sh
+npm install --save-dev @babel/plugin-transform-modules-systemjs
+```
+

+
+```json
+{
+ "plugins": ["@babel/plugin-transform-modules-systemjs"]
+}

+
+With options:
+
+```json
+{
+ "plugins": [
+ ["@babel/plugin-transform-modules-systemjs", {
