Question

settings.js

exports.dbConfig = {
user: "gpolat",
password: "alphalpha",
server: "DESKTOP-LK9JDJJ",
database: "mydemo",
port: 1433
};
exports.webPort = 9000;

db.js

var sqlDb = require("mssql");
var settings = require("../settings");

exports.executeSql = function (sql, callback) {

var conn = new sqlDb.Connection(settings.dbConfig);
conn.connect()
    .then(function () {
        var req = new sqlDb.Request(conn);
        req.query(sql)
            .then(function (recordset) {
                callback(recordset);
            })
            .catch(function (err) {
                console.log(err);
                callback(null, err);
            });
    })
    .catch(function (err) {
        console.log(err);
        callback(null, err);
    });

};
