    const express = require("express");

    const app = express();

• To use the library, require it in the file where your entry file is like this

    // With require
    const { BackEndSocket } = require("backend-socket")

• Now initialize it

    const express = require("express");
    const { BackEndSocket } = require("backend-socket")

    const app = express();

    // It requires the app and port in which the app runs
    const connection = new RealTimeConnection(app, 3042);
