# Visual Studio Code Extension

> Browse GrowthBook feature flags in VS Code, copy keys, and open flags in the dashboard after adding a .growthbook.json config file.

The GrowthBook [Visual Studio Code extension](https://marketplace.visualstudio.com/items?itemName=GrowthBook.growthbook) lists your project's feature flags in the editor so you can browse them, copy a key, and open a flag in the GrowthBook dashboard.

Install it from the [Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=GrowthBook.growthbook).

## Features

After you install and configure the extension, a **Features** panel appears in the bottom left of VS Code.

* **List flags.** Every feature for the configured project appears in the panel.
* **See evaluation details.** The value type shows next to the flag name. Hover a flag to see its default value and targeting rules.
* **Copy a feature key.** Hover a flag and use the copy action to put the key on the clipboard.
* **Edit in GrowthBook.** Hover a flag and use the edit action to open that feature in your browser.

## Configuration

The extension reads a `.growthbook.json` file in your project. Create it in any of these ways:

* Click **Add Configuration** in the Features panel.
* Run **GrowthBook: Create a .growthbook.json configuration file** from the command palette (`Cmd`+`Shift`+`P` on macOS, `Ctrl`+`Shift`+`P` on Windows and Linux).
* Create the file yourself:

```json theme={null}
{
  "featuresEndpoint": "https://cdn.growthbook.io/api/features/sdk-YOUR_CLIENT_KEY",
  "appHost": "https://app.growthbook.io"
}
```

* **`featuresEndpoint`:** The features API URL from **SDK Configuration** → **SDK Connections** in GrowthBook. Self-hosted instances typically look like `http://localhost:3100/api/features/sdk-YOUR_CLIENT_KEY`.
* **`appHost`:** The GrowthBook app URL the edit-in-browser action should open. Use your Cloud app URL, or the URL of your self-hosted instance.

Do not commit `.growthbook.json` if it contains a client key you do not want in version control. Check in a `.growthbook.json.example` instead and copy it locally.

## Commands

Open the command palette and type `GrowthBook` to run:

* **Refresh features**
* **Create a .growthbook.json configuration file**
