Loader must be a function like this:

` javascript
const yourLoader = ({ memo, parse, fileCode }) => {
/**
* @memo
* @memo._import { from:string }:[]
* @memo._export { type:string }:[]
* @memo._url: string
*/

/**
* @parse
* goto: https://www.npmjs.com/package/@babel/parser
*/

/**
* @fileCode { string }
*/

const newMemo = {
_import: [],
_export: [],
};

return {
...memo,
...newMemo
};
};
module.exports = yourLoader;
