### Via Node API
|
|

require("@babel/core").transform("code", {

});
|

|
|
## Options
|
|
|
|
### `legacy`
|

Use the legacy (stage 1) decorators syntax.
|
|
|
|
### `decoratorsBeforeExport`
|
|
|
|
`boolean`, defaults to `true`.
|
|
|
|
```js
|
|
// decoratorsBeforeExport: true
|
|
@decorator
|
|
export class Foo {}
|
|
|
|
// decoratorsBeforeExport: false
|
|
export @decorator class Bar {}
|
|
```
|
|

|
This option was added to help tc39 collect feedback from the community by allowing experimentation with both possible syntaxes.
