Quickstart

Initialize the ldClient with your client side ID

import { init as initLD } from '@netlify/launchdarkly-server-sdk';

export default {
  async fetch(request: Request, env: Bindings): Promise<Response> {
    const clientSideID = 'test-client-side-id';
    const flagKey = 'testFlag1';
    const context = { kind: 'user', key: 'test-user-key-1' };

    // init the ldClient, wait and finally evaluate
    const client = initLD(clientSideID);
    await client.waitForInitialization();
    const flagValue = await client.variation(flagKey, context, false);

    return new Response(`${flagKey}: ${flagValue}`);
  },
};
