Calling the MiniSearch constructor causes typescript error `TypeError: minisearch_1.default is not a constructor`

I've seen folks have this similar issue, but it persists and isn't clear how to get it working:

In package.json

 "dependencies": {
    "minisearch": "^6.0.1",
    "tslint": "^6.1.3",
    "typescript": "^4.9.5"
  },

Code in indes.ts

import MiniSearch from 'minisearch';

class User {
  userId = '';
  firstName: string = '';
  lastName: string = '';
  email: string = '';
  city: string = '';
}

const userCache = new MiniSearch<User>({ fields: ["userId", "email", "city"] });

Error:

ts-node src/index.ts 
/Users/leopoldodonnell/dev/arch/mini-search/src/index.ts:12
const userCache = new MiniSearch<User>({ fields: ["userId", "email", "city"] });
                  ^

This could be my environment or something subtile in the module - either way I'm hoping someone will have seen and addressed this.

Hi @leopoldodonnell , I see you are using TypeScript, did you enable in your .tsconfig.json the option esModuleInterop ?

Thanks @lucaong - I had added and removed it after following various threads - this addresses the issue

Happy that it helped :)
