Secret Data
To Prevent sensitive data (e.g. Database PW, Connect String, Deploy Key) included in the source code directly, we may need to import those value by enviromment variables.
Also, we may use this method to enhance the reuse of several variables.

yarn add dotenvCreate a .env file at you root

import express, { Request, Response } from "express";

app.get("/", function (req: Request, res: Response) {
res.end("Hello mom!");
});
