javascript - display string on client side by fetching data from server side

Question

I was trying to display a string on the client-side by fetching the result from serverside but for some reason, it is not displaying the fetched data. When I console log the variable straight on the js file the server successfully prints the string. The program is not exporting the variable to the client-side to display it. I can't figure out where I went wrong. Any help is appreciated. Thanks in advance.

const router = require("express").Router();
const {
  callName
} = require("pathJs");

router.route("PathRoute").get(async(req, res) => {
  const Result = await callName();
  return res.json(Result);
});


module.exports = router;

There is no export in pathJs and you want name() to return an object containing liner. You need

function name() {
  const liner = "this works"
  console.log(liner)
  //updated
  return {liner};

}

async function callName() {
  const data1 = await name()
  return data1;

}

callName()

module.exports = { callName };

The backend is probably crashing with TypeError: callName is not a function while handling the request and therefore doesn't send a response.
