[docs] how to use typescript-go lsp

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.
