 The [rescript-vscode](https://github.com/rescript-lang/rescript-vscode) plugin contains a language server than can be power other editors. I recommend using [mason.nvim](https://github.com/williamboman/mason.nvim) to install the language server. It will download the `vsix` file from the latest stable release and add it to the Neovim `PATH` as `rescript-lsp`.
