Package Maintainers Call for Improvements to GitHub’s New npm Security Plan
Maintainers back GitHub’s npm security overhaul but raise concerns about CI/CD workflows, enterprise support, and token management.
@flags-sdk/launchdarkly
Advanced tools
The LaunchDarkly provider for the Flags SDK contains support for LaunchDarkly's Feature Flags.
The Statsig provider is available in the @flags-sdk/statsig
module. You can install it with
npm i @flags-sdk/launchdarkly
NOTE: The LaunchDarkly Vercel integration must be installed on your account, as this adapter loads LaunchDarkly from Edge Config. The adapter can not be used without Edge Config.
Import the default adapter instance ldAdapter
from @flags-sdk/launchdarkly
:
import { ldAdapter } from '@flags-sdk/launchdarkly';
The default adapter uses the following environment variables to configure itself:
export LAUNCHDARKLY_CLIENT_SIDE_ID="612376f91b8f5713a58777a1"
export LAUNCHDARKLY_PROJECT_SLUG="my-project"
# Provided by Vercel when connecting an Edge Config to the project
export EDGE_CONFIG="https://edge-config.vercel.com/ecfg_abdc1234?token=xxx-xxx-xxx"
import { flag, dedupe } from 'flags/next';
import { ldAdapter, type LDContext } from '@flags-sdk/launchdarkly';
const identify = dedupe(async (): Promise<LDContext> => {
return {
key: 'user_123',
};
});
export const showBanner = flag<boolean, LDContext>({
key: 'show-banner',
identify,
adapter: ldAdapter.variation(),
});
Create an adapter by using the createLaunchDarklyAdapter
function:
import { createLaunchDarklyAdapter } from '@flags-sdk/launchdarkly';
const adapter = createLaunchDarklyAdapter({
projectSlug: 'my-project',
ldClientSideKey: '612376f91b8f5713a58777a1',
edgeConfigConnectionString: process.env.EDGE_CONFIG,
});
Please check out the LaunchDarkly provider documentation for more information.
