Webpack loader ругается. Как использовать jsx source файлы внутри node_modules?

./node_modules/packageName/file.jsx
./main.js

import * as CUSTOM from './node_modules/packageName/file.jsx'

export function custom() {

}

ERROR in ./~/packageName/src/js/custom.jsx
Module parse failed:PATH_TO_PROJECT/node_modules/packageName/file.jsx Line 1: Unexpected token
You may need an appropriate loader to handle this file type.
| export function CUSTOM() {
| }

 @ ./src/js/main.js
