Lancedarkly toggle view


Switching between VS Code, LaunchDarkly web app and other toggle integrations is inconvenient during development. Also, the LaunchDarkly app does not provide a view of toggle states (on|off) for all environments.


A VS Code extension to bring LaunchDarkly toggle management closer to your development environment and show all environment toggle states. Toggle on|off from VS Code.

Get started

  1. You will need a LaunchDarkly account.

  2. From LaunchDarkly you will need to generate an Access Token. You can find it under: Account Settings -> Access Tokens -> Your access tokens.

  3. Set the role to writer to update toggle state (Turn toggles on/off).

  4. Default Project key. It's all lowercase and highlighted in gray. You can find it under: Account Settings -> Projects -> Your projects

Update your setting in VS Code under LanceDarkly. See image below:

LanceDarkly Settings


  • ctrl+shift+p -> LanceDarkly: List all toggles Opens a new tab listing all toggles. Selecting a toggle shows you details about it.

Extend the toggle details view with third party data.

Create a folder in your home directory called lancedarkly with a file called plugins.js: %user%/lancedarkly/plugins.js.

The plugin function is called when the LanceDarkly: List all toggles command is called.

Plugin API:

Only change the title and fields properties. Fields must be a 2D array.

The detailFields will pass through the toggle key.

Maximum of four fields and unlimited rows. First field has LanceDarkly label style applied.

Field widths: 20% 15% 15% 50%

// plugins.js

async function plugins() {
  const asyncData = await thirdPartyData(); // resolve data before turning API.
  return [
      detailFields(key) {
        return {
          title: "Title",
          fields: [
            ["Production", "key", "guid", "random"],
            ["Integration", "key", "guid", "random"]

exports.plugins = plugins;
