gopls, the Go language server

gopls is the official Go language server developed by the Go team. It was developed in response to the release of Go modules, and it is the recommended approach when working with Go modules in VS Code.

gopls is currently in an alpha state, so it is not enabled by default. Please note that gopls only supports Go versions above 1.12.

gopls has its own documentation pages, and they should be treated as the source of truth for how to use gopls in VS Code.



This extension functions by shelling out to a number of command-line tools. This introduces complexity, as each feature is provided by a different tool. Language servers enable all editors to support all programming languages without these individualized tools. They also provide speed improvements, as they can cache and reuse results.

gopls is the official Go language server. Using gopls will enable the VS Code Go extension to provide high-quality Go support as the language evolves.

To learn more about the context behind gopls, you can watch the Go pls, stop breaking my editor talk at GopherCon 2019.

Enable the language server

To start using the language server, set "go.useLanguageServer": true in your VS Code Go settings.

You should see a prompt to install gopls. If you do not see a prompt, please run the Go: Install/Update Tools command and select gopls.

Automatic updates

The gopls team releases new versions of gopls approximately once a month (release notes). The Go extension will automatically detect that a new version has been released, and a pop-up will appear prompting you to update.

If you would like to opt-out of these updates, set "go.useGoProxyToCheckForToolUpdates" to false.


There are a number of VS Code Go settings for controlling the language server.

  • "go.languageServerExperimentalFeatures" allows you to disable certain features.
    • "diagnostics": false disables diagnostic warnings from gopls. You might want to disable these if you don't like the diagnostics changing as you type.
    • "documentLink": false disables document links. The reason to disable these is explained in golang/go#39065: the Ctrl+Click shortcut for clicking on a link collides with the Ctrl+Click shortcut for go-to-definition.
  • "go.languageServerFlags" allows you to pass flags to the gopls process.
    • The -rpc.trace flag enables verbose debug logging.

Ignored settings

A number of the extension's settings are not passed in to gopls. We are working on unifying all of the settings, but some may still be ignored. These include:

These configurations can be passed to gopls via your environment or the gopls.env setting. Learn more in the gopls VS Code documentation.

gopls settings block

gopls exposes much more configuration. However, because gopls is in a state of rapid development and change, these settings change frequently. Therefore, we have not yet built these settings into the Go extension.

As shown in the gopls VS Code user guide, you can still configure these settings through VS Code by adding a "gopls" block to your settings.json file (Command Palette -> Preferences: Open Settings (JSON)). You will see an Unknown Configuration Setting warning, but the settings will still work. Add any settings there, and gopls will warn you if they are incorrect, unknown, or deprecated.

A full list of gopls settings is available in the gopls settings documentation.
