How to connect to SQL Server with windows authentication from Node.JS using mssql module

Question

Hi I\'m unable to connect to SQL server that is using windows authentication in node js. I\'m using the mssql module. The error message is :

[ConnectionError         


        

Answer 1

I've tried many variations and this is my complete solution.
I'm using SQL server Express.
I'm connecting, in the first instance, to the MASTER database only.
You only NEED to change "YOURINSTANCE\\SQLEXPRESS".
(Be sure to maintain the double-slash above!!!)
I'm using INTEGRATED SECURITY too.
The query relies on nothing at all (in your database).
You need to add your node packages
  ==> NPM INSTALL MSSQL and
  ==> NPM INSTALL msnodesqlv8
Hopefully, your connection issues will be a thing of the past.
Maybe.
Please.

// More here -> https://www.npmjs.com/package/mssql
var sql = require('mssql/msnodesqlv8');
var config = {
  connectionString: 'Driver=SQL Server;Server=YOURINSTANCE\\SQLEXPRESS;Database=master;Trusted_Connection=true;'
};
sql.connect(config, err => {
  new sql.Request().query('SELECT 1 AS justAnumber', (err, result) => {
    console.log(".:The Good Place:.");
    if(err) { // SQL error, but connection OK.
      console.log("  Shirtballs: "+ err);
    } else { // All is rosey in your garden.
      console.dir(result);
    };
  });
});
sql.on('error', err => { // Connection borked.
  console.log(".:The Bad Place:.");
  console.log("  Fork: "+ err);
});
