Quick Setup

This assumes that you have already installed the LaunchDarkly Node.js SDK, or a compatible edge SDK.

  1. Install this package with npm or yarn:
npm install @launchdarkly/server-sdk-ai --save
  1. Create an AI SDK instance:
// The ldClient instance should be created based on the instructions in the relevant SDK.
const aiClient = initAi(ldClient);
  1. Evaluate a model configuration:
  const config = await aiClient.modelConfig(
    aiConfigKey!,
    context,
    { enabled: false },
    { myVariable: 'My User Defined Variable' },
  );

For an example of how to use the config please refer to the examples folder.

About LaunchDarkly

  • LaunchDarkly is a continuous delivery platform that provides feature flags as a service and allows developers to iterate quickly and safely. We allow you to easily flag your features and manage them from the LaunchDarkly dashboard. With LaunchDarkly, you can:
    • Roll out a new feature to a subset of your users (like a group of users who opt-in to a beta tester group), gathering feedback and bug reports from real-world use cases.
    • Gradually roll out a feature to an increasing percentage of users, and track the effect that the feature has on key metrics (for instance, how likely is a user to complete a purchase if they have feature A versus feature B?).
    • Turn off a feature that you realize is causing performance problems in production, without needing to re-deploy, or even restart the application with a changed configuration file.
    • Grant access to certain features based on user attributes, like payment plan (eg: users on the ‘gold’ plan get access to more features than users in the ‘silver’ plan).
    • Disable parts of your application to facilitate maintenance, without taking everything offline.
  • LaunchDarkly provides feature flag SDKs for a wide variety of languages and technologies. Check out our documentation for a complete list.
