Split OpenFeature Provider for NodeJS

Overview

This Provider is designed to allow the use of OpenFeature with Split, the platform for controlled rollouts, serving features to your users via the Split feature flag to manage your complete customer experience.

Compatibility

Getting started

Below is a simple example that describes the instantiation of the Split Provider. Please see the OpenFeature Documentation for details on how to use the OpenFeature SDK.

Add the Split provider

npm install @splitsoftware/openfeature-js-split-provider

Confirm peer dependencies are installed

npm install @splitsoftware/splitio
npm install @openfeature/js-sdk

Register the Split provider with OpenFeature

const OpenFeature = require('@openfeature/js-sdk').OpenFeature;
const SplitFactory = require('@splitsoftware/splitio').SplitFactory;
const OpenFeatureSplitProvider = require('@splitsoftware/openfeature-js-split-provider').OpenFeatureSplitProvider;

const authorizationKey = 'your auth key'
const splitClient = SplitFactory({core: {authorizationKey}}).client();
const provider = new OpenFeatureSplitProvider({splitClient});
openFeature.setProvider(provider);

Use of OpenFeature with Split

After the initial setup you can use OpenFeature according to their documentation.

One important note is that the Split Provider requires a targeting key to be set. Often times this should be set when evaluating the value of a flag by setting an EvaluationContext which contains the targeting key. An example flag evaluation is

const client = openFeature.getClient('CLIENT_NAME');

const context: EvaluationContext = {
  targetingKey: 'TARGETING_KEY',
};
const boolValue = await client.getBooleanValue('boolFlag', false, context);

If the same targeting key is used repeatedly, the evaluation context may be set at the client level

const context: EvaluationContext = {
  targetingKey: 'TARGETING_KEY',
};
client.setEvaluationContext(context)

or at the OpenFeatureAPI level

const context: EvaluationContext = {
  targetingKey: 'TARGETING_KEY',
};
OpenFeatureAPI.getInstance().setCtx(context)

If the context was set at the client or api level, it is not required to provide it during flag evaluation.
