I am trying to import a local module on a node.js application and I do not seem to be able to.

modules/date.js :

const getDate = () => {...};
const getDay = () => {...};
export {getDate, getDay};

app.ts :

import {getDay, getDate} from "/modules/date";
//import {getDay, getDate} from "/modules/date.js"; doesn't work either

The error :
Cannot find module ‘/modules/date’ or its corresponding type declarations.ts(2307)

Config files

package.json :

    "skipLibCheck": true                                 /* Skip type checking all .d.ts files. */
  }
}

Do you know what I am missing ?

Thank you.
