use `vim.lsp.buf.rename` to rename using lsp. for example i use `vim.keymap.set("n", "<leader>rn", vim.lsp.buf.rename, opts)` to rename.

Thanks for the pointer!

try something like:

    vim.keymap.set('n', 'gr', function()
      local clients = vim.lsp.get_clients({ bufnr = 0 })
      for _, client in ipairs(clients) do
        if client.server_capabilities.renameProvider then
          vim.lsp.buf.rename()
          return
        end
      end
    end)

require('lspconfig')['tsserver'].setup{ on_attach = on_attach, ... }

local on_attach = function(client, bufnr) vim.keymap.set('n', '<leader>rn', vim.lsp.buf.rename, bufopts) end
