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.

This SDK is compatible with Go 1.19 and higher.

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.

import (
    "github.com/open-feature/go-sdk/pkg/openfeature"
    splitProvider "github.com/splitio/split-openfeature-provider-go"
)

provider, err := splitProvider.NewProviderSimple("YOUR_SDK_TYPE_API_KEY")
if err != nil {
    // Provider creation error
}
openfeature.SetProvider(provider)

If you are more familiar with Split or want access to other initialization options, you can provide a SplitClient to the constructor. See the Split Go SDK Documentation for more information.

import (
    "github.com/open-feature/go-sdk/pkg/openfeature"
    "github.com/splitio/go-client/v6/splitio/client"
    "github.com/splitio/go-client/v6/splitio/conf"
    splitProvider "github.com/splitio/split-openfeature-provider-go"
)

cfg := conf.Default()
factory, err := client.NewSplitFactory("YOUR_SDK_TYPE_API_KEY", cfg)
if err != nil {
    // SDK initialization error
}

splitClient := factory.Client()

err = splitClient.BlockUntilReady(10)
if err != nil {
    // SDK timeout error
}

provider, err := splitProvider.NewProvider(*splitClient)
if err != nil {
    // Provider creation error
}
openfeature.SetProvider(provider)

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

client := openfeature.NewClient("CLIENT_NAME");

evaluationContext := openfeature.NewEvaluationContext("TARGETING_KEY", nil)
boolValue := client.BooleanValue(nil, "boolFlag", false, evaluationContext)

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

evaluationContext := openfeature.NewEvaluationContext("TARGETING_KEY", nil)
client.SetEvaluationContext(context)

or at the OpenFeatureAPI level

evaluationContext := openfeature.NewEvaluationContext("TARGETING_KEY", nil)
openfeature.SetEvaluationContext(context)

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