its finally giving me a great experience in neovim. feels mega responsive, and features like find usage etc are working.

probably worth considering testing it here and documenting the option to use it.

below is how i configure it for neovim.

install the latest build;

npm install -g @typescript/native-preview

and then manually extend the lsp config;

local configs = require 'lspconfig.configs'

if not configs.tsgo then
  configs.tsgo = {
    default_config = {
      cmd = { 'tsgo', '--lsp', '--stdio' },
      filetypes = {
        'javascript',
        'javascriptreact',
        'javascript.jsx',
        'typescript',
        'typescriptreact',
        'typescript.tsx',
      },
      root_dir = require('lspconfig').util.root_pattern(
        'tsconfig.json',
        'pnpm-lock.yaml',
        'package-lock.json',
        'yarn.lock',
        'bun.lockb',
        '.git'
      ),
    },
  }
end

you can register it in the same way you register other lsps.

make sure to disable/remove any other typescript lsp you might have had configured.

note: i haven't tested this yet on opencode, as waiting on overhaul release. working great for me in neovim, so suspect opencode support wouldn't be long around the corner if any issues. consider this a note for those interested in testing it though

for anyone interested in using the typescript-go lsp.

npm install -g @typescript/native-preview

and then add the following to your opencode config:

{
  "lsp": {
    "typescript": {
      "disabled": false,
      "command": "tsgo",
      "args": ["--lsp", "--stdio"]
    }
  }
}

this works for you? trying it on the new version of opencode and it hangs waiting for diagnostics

oh, i haven't tried opencode yet. waiting on the release. but in neovim its working great for me. i suspect it won't be long until its stable enough in opencode too. they feel really close to an overall stable experience. so much faster than the js version.

updated my comment to reflect this.

this is more a recommendation for docs and/or interested parties

wondering if there is an unbounded root context. as most of the tsgo lsp issues have revolved around over eager or underoptimised file watchers architecture.

also, happy to test this on my mac if there is a way to install the overhaul branch.

I tried this approach, and it didn't work. opencode refuses to open. I've been using typescript-go with VSCode/Cursor and the performance is outstanding (autocomplete, linting, etc), so I think lsp is in a good state.

I see that opencode uses oxlint, so I wonder if it's possible to leverage their tsgo integration with lsp.

https://oxc.rs/docs/guide/usage/linter/type-aware.html#type-checking-diagnostics

Based on this post --type-check lints and type-checks at the same time, so maybe it's possible to use the oxlint for typescript as lsp, potentially saving RAM usage?

@rubnogueira I did the config approach with great success, however I didn't call it "typescript" like they did, and I used npx to run the tsgo binary. I don't have that config on hand, but it was something along these lines:

{
  "$schema": "https://opencode.ai/config.json",
  "lsp": {
    "typescript": {
      "disabled": true
    },
    "tsgo": {
      "command": ["npx", "-y", "@typescript/native-preview@latest", "--lsp", "--stdio"],
      "extensions": [".cjs", ".mjs", ".js", ".jsx", ".ts", ".tsx", ".mts"]
    }
  }
}

This fixed a bunch of issues I was having in my monorepo with the default typescript lsp in opencode where it didn't seem to respect my per project tsconfig files.

Additionally you should probably open a new issue and link that instead as this is currently marked as closed.

@Destreyf #12522 :)

Thank you for your suggestion. Your solution is very similar to my PR implementation, but it detects if tsgo is available. Hopefully it is easy to review.
