How can I create a video calling test service for my users?

Sometimes, especially with the first call, there can appear problems, maybe the browser is not supported, the user’s microphone is muted, and so on. Or maybe the user just wants to check how they look/sound in the call.

I would love to offer my users the possibility to test a call without having to call a real person. Similar to the “Echo / Sound Test Service” from Skype.

Can you offer some suggestions on how to do this?

// Importing express module
const express = require(‘express’);
const app = express();

app.set(“view engine”, “ejs”);

// Calling the public folder

// Handling get request
app.get("/" , (req,res)=>{
res.send(“Welcome to GeeksforGeeks Video Call App”);

// Listing the server
app.listen(4000 , ()=>{
console.log(“Server running on port 4000”);
kindly test this code hopfully will be resolve your problem. thanks
