From what I can see, you are trying to connect to a Microsoft SQL server but you are using a MySQL client npm package for the connection. The correct package to connect to a MSSQL server in Node.js is mssql
Install this and check if the connection issue still persists. Also, if the MSSQL server is on your local then using localhost as host name with correct port number would work most of the time.
There are also Connection Strings that you can use to connect to the MSSQL server.
See the documentation here
