How to listen all interfaces instead of localhost only with Node Express app server?

To listen all interfaces instead of localhost only with Node Express app server, we call listen with '0.0.0.0'.

For instance, we write

const express = require("express");
const app = express();
app.listen(3000, "0.0.0.0");

to call app.listen with "0.0.0.0" to listen for all interfaces at port 3000.
