# @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
```
## Usage
### Via `.babelrc` (Recommended)
**.babelrc**
Without options:
```json
{
"plugins": ["@babel/plugin-transform-modules-systemjs"]
}
```
With options:
```json
{
"plugins": [
["@babel/plugin-transform-modules-systemjs", {
// outputs SystemJS.register(...)
"systemGlobal": "SystemJS"
}]
]
}
```
### Via CLI
```sh
babel --plugins @babel/plugin-transform-modules-systemjs script.js
```
### Via Node API
```javascript
require("@babel/core").transform("code", {
plugins: ["@babel/plugin-transform-modules-systemjs"]
});
```
