coc-tsserver

Tsserver language server extension for coc.nvim.

Tsserver is part of TypeScript which provide rich language features for javascript and typescript.

This extension is a fork of typescript-language-features extension which is bundled with VSCode. File type detect and syntax highlight are not supported by this extension, use other vim plugin instead.

Important note: from v2.0.0, tsserver module resolved first from global configuration tsserver.tsdk and use bundled module when not found, if tsserver.useLocalTsdk is enabled, workspace folder configured tsserver.tsdk or typescript module inside current workspace folder would be used when exists.

Install

In your vim/neovim, run command:

:CocInstall coc-tsserver

For yarn2 ( >= v2.0.0-rc.36) user want to use local typescript module:

  • Run command yarn dlx @yarnpkg/sdks vim, which will generate .vim/coc-settings.json, with content:

    {
  "eslint.packageManager": "yarn",
  "eslint.nodePath": ".yarn/sdks",
  "workspace.workspaceFolderCheckCwd": false,
  "tsserver.tsdk": ".yarn/sdks/typescript/lib"
}

Almost the same as VSCode.

    • Enabled by options starts with typescript.inlayHints or javascript.inlayHints.

Troubleshooting

  • Add "tsserver.log": "verbose" to your coc-settings.json (opened by command :CocConfig)
  • To trace LSP communication, add "tsserver.trace.server": "verbose" to your coc-settings.json
  • Restart coc server by command :CocRestart
  • Make the issue happen.
  • Open tsserver log file by command CocCommand tsserver.openTsServerLog
  • Open tsserver output channel by command CocCommand workspace.showOutput tsserver

If you find any issues, please create an issue.

Q & A

Q: React syntax not recognized by tsserver.

A: Make sure to use javascriptreact and typescriptreact for buffer filetype.

autocmd BufNewFile,BufRead *.tsx setlocal filetype=typescriptreact
autocmd BufNewFile,BufRead *.jsx setlocal filetype=javascriptreact

Add those autocmds to your vimrc.

Q: Automatic type acquisition not work.

A: configure tsserver.npm to your global npm path or configure "tsserver.disableAutomaticTypeAcquisition": false to disable automatic typings installation.

Q: The extension needs some time to work.

A: The initialize of tsserver requires some time, you can add g:coc_status to your status line, see :h coc-status. If your tsserver get slow, try exclude unnecessary files in your jsconfig.json/tsconfig.json, make sure typescript version > 4.9 and disable logging (disabled by default).

Q: Update import on file rename not work.

A: Make sure install watchman in your $PATH. Use command :CocCommand workspace.showOutput watchman to check watchman output.

Q: Not work with buffer just created.

A: Tsserver treat buffer without a disk file belongs to implicit project, VSCode could work because VSCode create empty file first for buffer, save the buffer to disk to make tsserver work.

Q: Not work with my javascript project.

A: Configure jsconfig.json to make tsserver understand your code. Some features may still not work well, it's recommended to use typescript.

Q: Not work on WSL.

A: Copy you project files from mounted dirs to linux home otherwise tsserver may not work properly.
