Heap

Split + Heap

Split impressions describe the treatment that each user receives when a feature flag is evaluated. Attach flag names and treatments as Heap events properties for a user's session.

Prerequisites

To connect Heap to Split, you need,

• Split’s Javascript SDK evaluating feature flag treatments' client side
• Heap’s Web Javascript snippet

How to use

Implement both libraries

The code below implements both Split and Heap's JavaScript libraries, assuming both libraries are loaded in the header section. In this example, the Split SDK is wrapped with the class SplitIO. Be sure sure to update the key and authorizationKey fields in the factory initialization.

Split treatments are calculated for a list of feature flag names defined in an array variable splitNames. Be sure to update the array with the correct flag names.

Evaluate treatments

Once the treatments are fetched, the script uses heap.addEventProperties to add the feature flag names as a property name and the respective treatments as the value.

Add a prefix

A prefix of split. is added to each feature flag name in the below example to make it easier to filter in Heap.

Verify Split treatments as Heap event properties

Click a pageview event and view event properties.

Analyze Heap data by Split treatments

Create a graph of the count of page views filtering by Split feature flag names and treatments. Group by the flag name to see the count by treatment.

<script>
userId="bob";
heap.identify(userId);
class SplitIO {
    constructor() {
        this.isSDKReady=false;
        this.factory = splitio({
            core: {
                authorizationKey: 'BROWSER API KEY',
                key: userId,
            },
            storage: {
            type: 'LOCALSTORAGE'
            },
        });
        this.client = this.factory.client();
        this.client.on(this.client.Event.SDK_READY, () => {
            this.isSDKReady=true;
        });
    }
    applyFeatureFlags(featureNames) {
        return this.client.getTreatments(featureNames);
    }
    destroySplit() {
        this.client.destroy();
        this.client=null;
    }
}

function calculateTreatments() {
    splitNames=["sample_feature", "show_coupon", "enable_search"];
    treatments = mySplit.applyFeatureFlags(splitNames);

    var split_treatments ={};
    for (var i = 0; i < splitNames.length; i++) {
        console.log(splitNames[i]+": "+treatments[splitNames[i]]);
        split_treatments["Split."+splitNames[i]] = treatments[splitNames[i]];
    }
    heap.addEventProperties(split_treatments);
}

var mySplit = new SplitIO();
if (!mySplit.isSDKReady) {
    console.log("Split not ready yet");
    mySplit.client.on(mySplit.client.Event.SDK_READY, () => {
        calculateTreatments();
    });
} else {
    calculateTreatments();
}
