Hi @akashagarwal1321,
Make sure you have installed express and to add app.listen statement to your code. rest seems to work fine.
Refer to below code for your reference:

const express = require("express");
const app = express();
app.use("/", express.static(__dirname + "/public"));
function decodeQueryBase64(req, res, next) {
  for (let q in req.query) {
    // console.log(req.query[q])
    let data = req.query[q];
    data = new Buffer(data, "base64").toString("ascii");
    req.query[q] = data;
  }
  next();
}
app.get("/eval", decodeQueryBase64, (req, res) => {
  console.log(req.query);
  res.send("======eval result=====");
});

app.listen(4545, () => {
  console.log("Server started on http://localhost:4545");
});
