var config = {
//user: 'sa',
// password: '',
server: 'localhost',
database: 'TestDB',
debug: true
};
// connect to your database
sql.connect(config, function (err) {
if (err) console.log(err);
// create Request object
var request = new sql.Request();
// query to the database and get the records
request.query('select * from userInfo', function (err, recordset) {
if (err) console.log(err)
// send records as a response
res.send(recordset);
//console.log(recordset);
sql.close();
});

首先安装NPM包，
npm install msnodesqlv8然后将您的配置变量更改为
const sql = require('mssql/msnodesqlv8')
var config = {
server: 'localhost',
driver: 'msnodesqlv8',
database: 'TestDB',
debug: true,
options: {
trustedConnection: true
}
