Sending DevCycle Data to External Destinations

This topic explains how to send Feature and/or experimentation data to external destinations.

Some of our users prefer to use their own data warehouse and tools to analyze Feature and experiment data. Given this need, DevCycle provides ways to pipe data to any location of your choice.

In this guide, we provide code examples for the Node.js, Javascript, Android, and iOS SDKs on how to pull Experiment and Variation information from the DevCycle SDK for a given user and pass it to an example data analytics platform, such as Adobe.

While the specifics differ slightly between SDKs, the concept is largely the same. DevCycle has a method called getAllFeatures which provides a JSON map of the Features (Experiments) and Variations that a user received. This map can then be passed to an analytics provider in whatever format or context is desired. While the details below provide code specific to each SDK, the general documentation for the getAllFeatures method can be found here.

The format of the getAllFeatures response looks like this:

{
 "your-cool-feature": {
   "_id": "123456",
   "key": "your-cool-feature",
   "type": "release",
   "_variation": "333345",
   "variationName": "Some Variation",
   "variationKey": "some-variation"
 },
 "an-experiment": {
   "_id": "234567",
   "key": "an-experiment",
   "type": "experiment",
   "_variation": "444123",
   "variationName": "Treatment",
   "variationKey": "treatment"
 }
}

Given DevCycle may be used for experimentation, feature flagging and remote configuration, the “type” field in the response can be used to either filter or augment the data that is being sent to your chosen destination.

Note: The details specific to your analytics destination should be reviewed and verified by your team to ensure the accuracy and desired format of the data.

Code Examples for Adobe​

DevCycle Code for Node.js​

    const user = { user_id: '123' }
    const features = devcycleClient.allFeatures(user);
    const variations = {};
    Object.values(features).forEach((feature) => {
        variations[feature.key] = feature.variationName;
    })
    Analytics.trackAction("DVC_Features", variations);

DevCycle Code for Javascript​

    const features = devcycleClient.allFeatures();
    let variations = [];
    Object.values(features).forEach((feature) => {
        variations.push(`${feature.key}:${feature.variationName}`);
    })
    omtr.eVarNumber = variations.join(',');

DevCycle Code for Android (Java)​

import com.devcycle.sdk.android.model.Feature;

HashMap<String, String> variations = new HashMap<>();
Map<String, Feature> features = devcycleClient.allFeatures();
for (Feature feature : features.values()) {
     variations.put(feature.getKey(), feature.getVariationName());
}

Analytics.trackAction("DVC_Features", variations);

Link to Android Documentation

DevCycle Code for iOS (Swift)​

var variations: [String: String] = [:]
let features: [String: Feature] = self.devcycleClient!.allFeatures()
for featurekey in features.keys {
    let variation = features[featurekey]?.variationName
    variations[featurekey] = variation
}

MobileCore.track(action: "DVC_Features", data: variations)
