### `chooseJSCodeshiftParser(file: string): string | Parser`

```js

const chooseJSCodeshiftParser = require('jscodeshift-choose-parser')

```

Intelligently chooses a parser for a given file. Basically:

- If extension is `.ts` or `.tsx` return `'ts'`/`'tsx'` depending on extension

- Else if `@babel/core` is installed, return parser that uses with `@babel/core` using local babel config

- Else return `undefined`

The default `babylon` parser in `jscodeshift` **does not use your local babel config** AFAIK. This package

returns a parser that **does use your local babel config**.

### Example in a transform

```js

const chooseJSCodeshiftParser = require('jscodeshift-choose-parser')

module.exports = function(fileInfo, api) {

  const parser = chooseJSCodeshiftParser(fileInfo.path)

  return api.jscodeshift

    .withParser(parser)(fileInfo.source)

    .findVariableDeclarators('foo')

    .renameTo('bar')

    .toSource()

}

```
