For Go API client (lang: go), there are about 40 PRs (enhancements, bug fixes)[1] to Go API client since https://github.com/swagger-api/swagger-codegen/pull/1747 was merged into master. Please pull the latest master to give it another try and see if the Go API client meets your requirement.
For NodeJS server (lang: nodejs-server, renamed from nodejs), I agree it's not in its best form and there are still many rooms for improvement. If you've any feedback, please open a ticket via https://github.com/swagger-api/swagger-codegen/issues
For NodeJS client (lang: javascript), please give it a try as there may be confusion before that `nodejs` (deco) implies the NodeJS API client.
