Poor completion perfomance

[victorkamoto]

Great plugin btw

Typescript-tools so far has been a better alternative for typescript-language-server. The completions however can be quite slow. You heve to wait for a second or two before getting completions. There's visible lag. Is there a workaround/tsserver configuration to remedy this? Or is it a known issue?

Using default config btw (lazy.nvim)

return {
  {
    "pmizio/typescript-tools.nvim",
    lazy = true,
    ft = { "typescript", "javascript", "javascriptreact", "typescriptreact" },
    dependencies = { "nvim-lua/plenary.nvim", "neovim/nvim-lspconfig" },
    opts = {},
  },
}

              },
            },
          },
        }

        }

can you elaborate on this?

It significantly improves completion performance, as explained in the link on that post: https://github.com/yioneko/vtsls?tab=readme-ov-file#bad-performance-of-completion

tsserver could throw out plenty of completion entries, most of them are globally accessible variables, modules or namespaces. Some LSP clients have poor performance for fuzzy matching or filtering, and cause noticeable delay of completion.

vtsls.experimental.completion.enableServerSideFuzzyMatch: before returning all the completion candidates from tsserver, the server will do fuzzy matching and filter out entries with no match. This can reduce the number of invalid entries in the response.

Shouldn't this be re-opened? It was closed as "not planned" because some other plugin has a fix for it?

Is there any workaround here? This makes typescript-tools unusable for me as it feels laggy when typing because thousands of completion items are being returned by the LSP. I gotta assume there is something I am missing or misconfiguring. Thanks in advance!

@austinbutler I was using vtsls but have other annoying issues like sometimes goto definition gets wacky (gets confused and takes me to wrong location) and often goto def / refs will hang and take several seconds before it properly "resolves" and takes me there.

Have you noticed those issues?

[austinbutler]

I don't think so, but maybe I'm just used to it
