LaunchDarkly sample OpenFeature Server-Side Node.js application

We've built a simple console that demonstrates how LaunchDarkly's OpenFeature provider works.

The LaunchDarkly OpenFeature provider for the Server-Side SDK for Node.js is designed primarily for use in multi-user systems such as web servers and applications. It follows the server-side LaunchDarkly model for multi-user contexts. It is not intended for use in desktop, browser, and embedded systems applications.

Supported Node versions

This sample is compatible with Node.js versions 18 and above.

Build instructions

  1. Install dependencies using npm install.

  2. Set the environment variable LAUNCHDARKLY_SDK_KEY to your LaunchDarkly SDK key. If there is an existing boolean feature flag in your LaunchDarkly project that you want to evaluate, set LAUNCHDARKLY_FLAG_KEY to the flag key; otherwise, a boolean flag of sample-feature will be assumed.

    export LAUNCHDARKLY_SDK_KEY="1234567890abcdef"
export LAUNCHDARKLY_FLAG_KEY="my-boolean-flag"

  3. On the command line, run npm start

You should receive the message ”The ${featureFlagKey} feature flag evaluates to ${flagValue}”.
