This article explains how to get formatting work with shell scripts: https://smarttech101.com/nvim-lsp-set-up-null-ls-for-beginners/

Basically you need shfmt and null-ls configured to use it.

(I have no affiliation with the site, just found it to solve my problem.)

Ideally we want to integrate a formatter into the server, but currently this is not supported.

If you want formatting in Helix you can use the shfmt binary out of the box with this setting: https://github.com/helix-editor/helix/wiki/External-binary-formatter-configuration#shfmt

Using null-ls you can get formatting via shfmt. Would be really cool to just integrate shfmt into the bash-language server so we don't need to use null-ls
