routeTo helper to handle params and query string

route.ts

import { generatePath } from 'react-router-dom';
import { stringify } from 'query-string';

const routeTo = (path: string, params: object, qs: object) => {
   const url = generatePath(path, params);
   
   return qs ? `${url}?${stringify(qs}` : url;  
}

history.push(routeTo('admin/view/:id', { id: 'ok'}, { anotherParam: 'value' }));

// resulting route
`/admin/view/ok?anotherParam=value`

You are missing a parenthesis on line 7 behind stringify(qs.

It should be
return qs ? `${url}?${stringify(qs)}` : url;
