Node.js Connection with SQL Server windows authentication - sql-server

Question

I'm trying to connect node.js to mssql in Windows Authentication mode. I installed the tedious,mssql and msnodesqlv8 modules, but I still can't figure out how to open a connection.
This is what I tried:
var sql = require('mssql');
var config = {
driver: 'msnodesqlv8',
server: 'POPPY-GI\\SQLEXPRESS',
database: 'NodinSports',
options:{
trustedConnection: true,
useUTC: true}}
sql.connect(config).then(function() {
new sql.Request().query('select * from users')
.then(function(recordset){
console.log(recordset);
}).catch(function(err) {
console.log(err);});
}).catch(function(err) {
console.log(err);});
After running I get a long error saying:
`ConnectionError`: Port for `SQLEXPRESS` not found in
`ServerName`;POPPYGI;`InstanceName;SQLEXPRESS;IsClustered`;No;Version;12.0.2000.8;;

I would be really thankful for any help.
FIXED:
In services.msc check if the followings are enabled:
SQL Server(*server_name*) -- in my case `SQLEXPRESS`
SQL Server Browser
SQL Server Agent(*server_name*) -- if you are using `SQLEXPRESS` this doesn't need to run
In SQL Server Configuration Manager -> Protocols for server_name: enable TCP/IP.
To make sure everything will be fine, check the port the server is using (SQL Server Configuration Manager -> SQL Native Client Configuration -> Client Protocols -> double click on TCP/IP -> Default Port ) , and add the port: *your_port* to the code in var config = { ... }.
Lastly, change var sql = require('mssql'); to var sql = require("mssql/msnodesqlv8");

Answer 1

Install the following modules:
"dependencies": {
"msnodesqlv8": "^0.4.14",
"mssql": "^4.1.0"
}
My node version: v8.1.4
const sql = require("mssql/msnodesqlv8");
const main = async () => {
const pool = new sql.ConnectionPool({
server: "myservername",
database: "mydbname",
options: {
trustedConnection: true
}
});
await pool.connect();
const request = new sql.Request(pool);
const query = `SELECT [FirstName]
,[LastName]
,[Email]
FROM [Dev].[Users]`;
const result = await request.query(query);
console.dir(result);
};
main();
(You can do it without async or older versions: https://stackoverflow.com/a/40406998/639575)

Answer 2

The solution given by beatoss works for windows but not for Linux/mac. The msnodesqlv8 driver only works for Windows. For Linux/mac environment, try odbc instead.

Answer 3

It may be too late to answer, but this recently happened with me and it drove me crazy!!! I was trying to connect my db to express and I was working with windows authentication mode. For two long days I kept googling and refreshing until I got this article: https://www.liquidweb.com/kb/troubleshooting-microsoft-sql-server-error-18456-login-failed-user/
So in a nutshell;
First I installed the msnodesqlv8 driver for windows authentication, then in the my server on ssms, I right clicked on my server then in properties and then security, I enabled sql server and windows authentication mode, then in the object explorer, clicked on the plus next to the server, then security, then logins. There I saw sa with a cross next to it. In it's properties, I changed my password to something easier to remember (optional), then in the status, set the login to enable. PHEW!
Now my config code: <br / >
const config = {
user: 'sa',
password: '123',
driver: "msnodesqlv8",
server: 'UZAIR-S_PC\\SQLEXPRESS',
database: 'LearningExpressJS',
options: {
trustedconnection: true,
enableArithAbort : true,
trustServerCertificate: true,
instancename : 'SQLEXPRESS'
},
port: 58018
}
This works finally !!!!!!!!!!!!!!!
