Connecting to mssql instances by instance name

[andresteyn]

Apologies if this has been addressed elsewhere, but I have searched extensively. How do I connect to a mssql instance such as localhost\sqlexpress?

I have tried all of the following:
npx typeorm-model-generator -h localhost -d sqlexpress\dbname -u sa -x my_password -e mssql -o .
npx typeorm-model-generator -h localhost\sqlexpress -d dbname -u sa -x my_password -e mssql -o .
npx typeorm-model-generator -h localhost/sqlexpress -d dbname -u sa -x my_password -e mssql -o .
npx typeorm-model-generator -h localhost\\sqlexpress -d dbname -u sa -x my_password -e mssql -o .
npx typeorm-model-generator -h sqlexpress -d dbname -u sa -x my_password -e mssql -o . -s sqlexpress

Discovering mssql server through instance name isn't supported at the moment. You should specify server by host and port instead.
