coc-tsserver

Tsserver language server extension for coc.nvim.

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

This extension is a fork of typescript-language-features extension which is bundled with VSCode.

Note: for React to work as expected, you need your JSX filetype to be javascript.jsx or javascriptreact and your TSX filetype to be typescript.jsx or typescript.tsx or typescriptreact. In coc.nvim, these filetypes are mapped to javascriptreact and typescriptreact because that's what tsserver uses. For filetype like typescript.javascript, you need configure g:coc_filetype_map variable in vimrc.

Note for javascript project, configure jsconfig.json to make tsserver understand your code.

Note: for rename import on file rename, you have to install watchman in your $PATH.

Note: for nvm users, you need configure tsserver.npm to your global npm path or configure "tsserver.disableAutomaticTypeAcquisition": false to disable automatic typings installation.

Note: tsserver could be quite slow to initialize on big project, exclude unnecessary files in your jsconfig.json/tsconfig.json.

Note: if you're using WSL, copy you project files from mounted dirs to linux home otherwise tsserver will not work properly.

  • 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"
    }
