- I am creating a react app that connects to a mysql database, but for some reason it is not making the connection My code is shown below: const path = require("path"); const express = require("express"); const bodyParser = require("body-parser"); const errorController = require("./controllers/error"); //const db = require("./util/database"); const app = express(); var mysql = require("mysql"); var con = mysql.createConnection({ host: "localhost", user: "root", password: "COP4710", }); con.connect(function (err) { if (err) throw err; console.log("Connected!"); }); app.use(bodyParser.urlencoded({ extended: false })); app.use(express.static(path.join(__dirname, "public"))); app.use(errorController.get404); app.listen(3000);If there is a database by the name StudentMarks in MongoDB then you can use use StudentMarks command to switch that database and start working on this database. But let’s assume that there is no database by the name StudentMarks in MongoDB. In this case if you still prefer use StudentMarks command than can be still OK and create the database and switch to it or would this command cause an error?Explain what happens in both scenarios?For how long does it take to run the database? Even if it's one more thing, I'll do it. A single action may be able to delete a maximum of how many times? It doesn't matter if it's used for a single ad or a series of ads. As a direct result of a single web search?
