If Node is your backend then JS is what you need to use. Whether directly or via Typescript.
JS is just the language. Avoiding JS on the front end is more about avoiding front end code, state management, mutations, a11y issues, frameworks etc. rather than the JS language itself!
It also means avoiding using available tools in a well tested OS that is a browser like service workers, WebRTC, etc. Not knowing how to use them efficiently isn't a feature.
It is a developer time tradeoff. If your app is mainly forms and not that interactive a framework like this would be OK. Internal crud tools would be an example. But you can’t use it for everything (you can’t use any framework for everything!)
