Is there a linter/prettier for typescript/javascript, for jupyterlab 4?

Running under a juoyterlab-4 instance [in docker, in my instance] - I have the kernel running just fine, and the `typescript-language-server` plugin gives me suggestions & auto-completion as expected.

The thing I'm missing now is a code-formatter (or a plugin for https://github.com/jupyterlab-contrib/jupyterlab_code_formatter)

Does anyone have any suggestions?
