svelte-language-server watcher doesn't work in neovim lspconfig

[ryoppippi]

I'm in the same problem with my sveltekit project.
I'm using typescript-svelte-plugin.
Although typescript files (like +page.server.ts) works realtime, diagnostics of .svelte file does not updated.

I'm configuring root_pattern( {"package.json", "tsconfig.json", "tsconfig.jsonc", "node_modules"}) for svelte language server

Okay, this is a truly hacky things, but I solved this problem with this setting

function on_attach(on_attach)
  vim.api.nvim_create_autocmd("LspAttach", {
    callback = function(args)
      local buffer = args.buf
      local client = vim.lsp.get_client_by_id(args.data.client_id)
      on_attach(client, buffer)
    end,
  })
end

on_attach(function(client, bufnr)
      vim.api.nvim_create_autocmd("BufWritePost", {
        pattern = { "*.js", "*.ts" },
        callback = function(ctx)
          if client.name == "svelte" then
            client.notify("$/onDidChangeTsOrJsFile", { uri = ctx.file })
          end
        end,
      })
    end)
end)

This is fixed in language-server 0.15.12. You don't need the workaround.

@jasonlyu123 i install the last version but not working and fixed using example of @ryoppippi

[jasonlyu123]

The workaround only solves part of the problem. The API used in the workaround was meant to assist file watching instead of replacing it. What is your neovim version? This issue is about a compatibility problem introduced in neovim 0.9.0.
