I wasn't able to find the answer to your question in the official Deno documentation. However, based on your message, I can provide some general advice on setting up formatting with Deno in Neovim using nvim-lspconfig. To configure Neovim to format your code using the settings from a deno.json file, you would typically need to ensure that the Deno language server is properly set up in your Neovim configuration. This usually involves adding a configuration block for Deno in your init.vim or init.lua file, depending on which configuration language you are using. Here's an example of how you might set up the Deno language server in Lua:

require'lspconfig'.denols.setup {
  -- Add your configuration settings here
  init_options = {
    lint = true,
    unstable = true,
  },
  root_dir = require'lspconfig'.util.root_pattern("deno.json", "deno.jsonc"),
}

require'lspconfig'.denols.setup {
  -- Add your configuration settings here
  init_options = {
    lint = true,
    unstable = true,
  },
  root_dir = require'lspconfig'.util.root_pattern("deno.json", "deno.jsonc"),
}

This configuration tells the Deno language server to use the deno.json or deno.jsonc file in the root of your project to configure the Deno runtime. Please note that this advice is not based on the Deno documentation, and you should double-check the accuracy of this advice. Additionally, since I don't have access to external links, I cannot review your dotfiles directly. Make sure to consult the nvim-lspconfig documentation and the Deno manual for more detailed instructions on integrating Deno with Neovim's LSP.

I find the setup easy with coc.nvim along with coc-deno extension. I Personally found it a bit challenging, so I skipped nvim-lspconfig. But if you want to try coc, here's a short reference on how to set it up ->.

awesome! thank you. I was able to get it with my nvim-lspconfig but it is still giving some issues so i will probably either convert over to coc, or I will check out biomejs

I'm currently going through the same process of trying to figure out why deno isn't formatting with lspconfig. What was your solution?

y@OP•3mo ago

I will send it to in here this afternoon. Works well now.

Install conform then add your deno formatter to ft by file type and enable format on save

rowvir•3mo ago

I guess I need to learn the overlap between NVIM's LSP and it's ability to format (like with ESLint) and trying to minimize the number of plugins I need to have installed and configured when they do much the same thing

What are you talking about? It appears that you don't even know how neovim works. Listen to me, do yourself a favour and start reading documentation :h lspconfig is a good start. ESLint is not a formatter - it's a linter. If you just want to quickly get up and running, add denols to your list of servers in your lspconfig, making sure that deno.enable and deno.lint are both set to true. Next, add this plugin https://github.com/stevearc/conform.nvim and include the following in its setup options:

local options = {
  formatters_by_ft = {
    lua = { "stylua" },
    css = { "deno_fmt" },
    html = { "deno_fmt" },
    javascript = { "deno_fmt" },
    typescript = { "deno_fmt" },
    json = { "deno_fmt" },
    jsonc = { "deno_fmt" },
    javascriptreact = { "deno_fmt" },
    typescriptreact = { "deno_fmt" },
    markdown = { "deno_fmt" },
  },

  format_on_save = {
    enabled = true,
    timeout_ms = 2000,
    lsp_fallback = true,
  },
}

local options = {
  formatters_by_ft = {
    lua = { "stylua" },
    css = { "deno_fmt" },
    html = { "deno_fmt" },
    javascript = { "deno_fmt" },
    typescript = { "deno_fmt" },
    json = { "deno_fmt" },
    jsonc = { "deno_fmt" },
    javascriptreact = { "deno_fmt" },
    typescriptreact = { "deno_fmt" },
    markdown = { "deno_fmt" },
  },

  format_on_save = {
    enabled = true,
    timeout_ms = 2000,
    lsp_fallback = true,
  },
}

Actually, I don't even think you need to include the configuration for js and ts since denols will run those for you and conform automatically handles lsp formatters if you have lsp_fallback enabled.

this looks similar to what i have @rowvir, i completely forgot. here is the repo https://github.com/wsoule/config.nvim check out these files (i have not looked over this in a while, so dont mind the bad code https://github.com/wsoule/config.nvim/blob/main/lua/custom/plugins/lsp.lua https://github.com/wsoule/config.nvim/blob/main/lua/custom/plugins/format.lua https://github.com/wsoule/config.nvim/blob/main/lua/custom/plugins/lint.lua
