erlang_ls VS elm-language-server

It goes without saying that creating a GitHub issue for the language server is a simpler way to track a potential bug, so please do that if you haven't already (https://github.com/erlang-ls/erlang_ls/issues). I understand that in same cases you may not share the code that triggers the issue, but other useful information can be provided that can help maintainers to figure out what is happening. In the case of VS Code, formatting on save is an editor setting: Preferences -> Editor -> Format on save. It could it be that you have another extension which is trying to format your code. You could check the client-side and server-side logs to verify whether VS Code sends format requests to the language server and if Erlang LS is replying to those.

Regarding user experience and tooling, I'd suggest you use an editor that is compatible with the elm language server: https://github.com/elm-tooling/elm-language-server VSCode is a good default choice. You'll also be interested in other toolings. elm-json (https://github.com/zwilias/elm-json) is great to simply install and uninstall dependencies. elm-format (https://github.com/avh4/elm-format) is a must since most active people in the community use it, and simply viewing your code being moved around on save is a good sign that you wrote something with a good syntax.
