| ### async transform(options?: object): TransformResult object | ||
| ### transform | ||
| `options` has following members: | ||
| ```js | ||
| async transform({ | ||
| parse?: (code: String) => ESTree, | ||
| code: String, | ||
| ast?: ESTree, | ||
| sourceMap?: Boolean = false, | ||
| importStyle?: String | async (moduleId) => String, | ||
| exportStyle?: String | async () => String, | ||
| nested?: Boolean, | ||
| warn?: (message: String, pos: Number) => void | ||
| }) | ||
| => TransformResult | ||
| ``` | ||
| * `parse?`: `function`. A parser function which can parse JavaScript code into ESTree. | ||
| * `code`: `string`. The JavaScript source code. | ||
| * `ast?`: AST object. If set then ignore `options.parse`. | ||
| * `sourceMap?`: `boolean`. If true then generate the source map. Default: `false` | ||
| * `importStyle?`: `string` or `function -> string`. The result must be `"named"` or `"default"`. Default: `"named"` | ||
| * `parse` is a parser function which can parse JavaScript code into AST. The module will use this function to parse `code`. You don't have to provide the `parse` function if `ast` is set. | ||
| When the value is a function, it recieves one argument: | ||
| * `code` is the JavaScript source code. | ||
| - `moduleId`: `string`. The module ID of `require("module-id")`. | ||
| * `ast` - if you already have the AST of the code, you can set it as `ast` so the module don't have to parse the code again. | ||
| * `exportStyle?`: `string` or `function -> string`. The result must be `"named"` or `"default"`. Default: `"named"` | ||
| * `nested?`: `boolean`. If true then analyze the entire AST, otherwise only top-level nodes are visited. If there is no nested require/exports/dynamic import statements, it is safe to keep it off. Default: `false`. | ||
| * `warn?`: `function`. This function is called when the transformer emmits a warning. The arguments are: | ||
| * `sourceMap` - if `true` then generate the source map. | ||
| - `message`: `string`. Warning message. | ||
| - `pos`: `number`. The position of the current node. | ||
| If undefined, the transformer would use global `console.error`. | ||
| * `importStyle` and `exportStyle` are used to decide how to transform import/export statements. The value or the value returned by the function must be `"named"` or `"default"`. By default, the transformer always prefer to use named exports for import/export statements. | ||
| `options.importStyle` and `options.exportStyle` could be async, and the return value would be cached (for `importStyle`, the value is cached for each `moduleId`). | ||
| If `importStyle` is a function, it will only be called once for each `moduleId` if needed. | ||
| The result object has following members: | ||
| If `exportStyle` is a function, it will only be called once if needed. | ||
| * `code`: string. The result JavaScript code. | ||
| * `map?`: object. The source map object generated by [`magicString.generateMap`](https://github.com/Rich-Harris/magic-string#sgeneratemap-options-). If `isTouched` or `options.sourceMap` is false then the map is null. | ||
| * `isTouched`: boolean. If false then the code is not changed. | ||
| * `warn` - the transformer uses `warn` function to emit a warning. If `warn` is not set then the transformer will print the message to the console using `console.error`. | ||
| If an error is thrown during walking the AST, the error has a property `pos` which points to the index of the current node. | ||
| ### TransformResult | ||
| ```js | ||
| { | ||
| code: String, | ||
| isTouched: Boolean, | ||
| map: Object | null | ||
| } | ||
| ``` | ||
| * `code` - the result ES source code. | ||
| * `isTouched` - if `true` then the code is changed. | ||
| * `map` is the source map object generated by [`magicString.generateMap`](https://github.com/Rich-Harris/magic-string#sgeneratemap-options-). Only available if `isTouched` and the `sourceMap` option are both `true`. | ||

| * 0.8.2 (Jul 2, 2019) | ||
| - Fix: nested export assignment doesn't check if exports is shadowed. | ||
