How to create two connections to different sql server in node.js?

Question

Node.js

I create a connection in this way
var mssql = require('mssql');
var pool1 = mssql.connect(config1, err => {
console.log(err);
});
var pool2 = mssql.connect(config2, err => {
console.log(err);
});
To which I get the error Global connection already exists
It turns out it is impossible to create two connections at the same time, without closing the previous one

Answer 1

Figured it out myself. Instead of connect, you need to use ConnectionPool(config).connect(err => {}). Apparently connect creates a pool and sets it as global, and if the global pool is already set, it throws an exception.
