`vscode-eslint-language-server` is a linting engine for JavaScript / Typescript.
It can be installed via `npm`:
```sh
npm i -g vscode-langservers-extracted
```
`vscode-eslint-language-server` provides an `EslintFixAll` command that can be used to format a document on save:
```lua
lspconfig.eslint.setup({
--- ...
on_attach = function(client, bufnr)
vim.api.nvim_create_autocmd("BufWritePre", {
buffer = bufnr,
command = "EslintFixAll",
})
end,
})
```
