# @flags-sdk/launchdarkly

## 1.1.1

### Patch Changes

- [#464](https://github.com/vercel/flags/pull/464) [`8913cf1`](https://github.com/vercel/flags/commit/8913cf157808eda595c9c0ed5f21e5c70a5f03ca) Thanks [@AndyBitz](https://github.com/AndyBitz)! - Upgrade `@vercel/global-config` from `1.5.0` to `1.5.1`

## 1.1.0

### Minor Changes

- [#452](https://github.com/vercel/flags/pull/452) [`58e1f5b`](https://github.com/vercel/flags/commit/58e1f5bcdf0dd3ef44ce689681882792b31851c4) Thanks [@luismeyer](https://github.com/luismeyer)! - Replace `@vercel/edge-config` with `@vercel/global-config`.

  Rename the Edge Config adapter package to `@flags-sdk/global-config` and rename repository-owned Edge Config files, exports, types, options, variables, and environment variables to Global Config.

  The previous Edge Config names remain available as deprecated aliases, and the previous environment variables are still honored as fallbacks, so existing code keeps working without changes.

## 1.0.0

### Major Changes

- [#418](https://github.com/vercel/flags/pull/418) [`5488865`](https://github.com/vercel/flags/commit/54888657e895d2c5e32f96baf545b9f798045c2c) Thanks [@mbrakken](https://github.com/mbrakken)! - Support the native LaunchDarkly Marketplace integration.

  **Breaking changes:**

  - The default adapter (`ldAdapter`) now reads the Edge Config connection string from the `EXPERIMENTATION_CONFIG` environment variable instead of `EDGE_CONFIG`. This aligns with the native LaunchDarkly Marketplace integration and matches the behavior of other adapters (e.g. Statsig). `EDGE_CONFIG` is no longer read by the default adapter. The error thrown when `EXPERIMENTATION_CONFIG` is not set changed to `LaunchDarkly Adapter: Missing EXPERIMENTATION_CONFIG environment variable`.

    **If you use the legacy LaunchDarkly Vercel integration** (which provides the connection string as `EDGE_CONFIG`), pass the connection string explicitly with `createLaunchDarklyAdapter`:

    ```ts
    import { createLaunchDarklyAdapter } from "@flags-sdk/launchdarkly";

    const ldAdapter = createLaunchDarklyAdapter({
      projectSlug: process.env.LAUNCHDARKLY_PROJECT_SLUG,
      clientSideId: process.env.LAUNCHDARKLY_CLIENT_SIDE_ID,
      edgeConfigConnectionString: process.env.EDGE_CONFIG,
    });
    ```
