How do I properly write the server and port for an Express typescript API that uses mssql with the tedious driver?

1. 1Check the SQL Server instance name and port number using the SQL Server Configuration Manager
2. 2Update the server property in the connection configuration to use the correct instance name and port number
3. 3Use the format 'server\instance' for the server property if the instance name is required
4. 4Verify the port number is correct and not blocked by a firewall
5. 5Test the connection using the mssql package to ensure it is working as expected

Backend developers and DevOps engineers working with Express and mssql will benefit from this lesson to ensure reliable database connections

💡 The server property should be in the format 'server\instance' if the instance name is required, and the port number should match the one configured in the SQL Server instance
