Hi everyone I have been facing an issue in js sdk and reaching out for help Issue: On updating a feature flag value, getting those values after couple of app session Details: I'm using the feature flag feature of GB in a react native application Currently I don't want to auto refresh the features in a single app session, so while initialising the sdk, I'm passing auto refresh as false and because of that no subscribedInstances are created. The issue is that when I fetch feature,

onNewFeatureData

is called and it sets the newly fetched features only when you have any

subscribedInstances

. Since I don't have any subscribed instances, the values are not set in the same app session but only updates the cache.

function onNewFeatureData(
  key: string,
  cacheKey: string,
  data: FeatureApiResponse
): void {
  ......
  updatePersistentCache();

  // Update features for all subscribed GrowthBook instances
  const instances = subscribedInstances.get(key);
  instances && instances.forEach((instance) => refreshInstance(instance, data));
}

Proposed solution: a straight forward solution would be to add a condition to check if auto refresh is enabled or not

if (instances) {
		//Update features for all subscribed GrowthBook instances
	  instances.forEach((instance) => setFeaturesOnInstance(instance, data));
	} else {
	  instance && data && setFeaturesOnInstance(instance, data);
	}

I wanted the understand the implications of these changes and is there any other way to solve this issue TIA!

Hello! quick question. we are considering Growthbook as self-hosted solution. Is there a list of functionality which is not available in self-hosted solution but only in Enterprise plan?

Hey guys, I am currently trying to link Matomo to GrowthBook. How do I have to implement this in the code if I use Angular to see results in GrowthBook afterwards?

Hi Growthbook team, Is there any way to set up attributes on growthbook such that if we pass any parameter to growthbook, it analyzes that under which experiment that parameter falls by using the attributes that we have set. Example lets say we have provided growthbook access to our database and provided it parameters in the database which it should analyze. Now let's say there's an api endpoint and we need to know which experiment that url falls into based on the parameters we have asked growthbook to analyze. So to summarize what I want to convey is that instead of sending attributes from our backend service and get to know which experiment it falls under.. can we configure attributes on growthbook side by providing it access to our database and growthbook then helps tell us which experiment any parameter(url for example) falls under

Hello, we consider using the self-hosted version of growthbook but we can not find any information if the docker container is capable of operation on multiple nodes when it will scale. Does anybody have information on that?

Hi there, I'm setting up GrowthBook for a React app + Dotnet.core API. Is it possible that the two SDK's will diverge and cause some discrepancies in experiment targeting? Would the two SDK will assign different variations the same experiment sometimes? What would you recommend to do to avoid this problem? Regards

Hey! We've been using Growthbook for a little bit now with our Google Analytics UA implementation for A/B testing experiments, and it's been so great that we'd like to start running multiple, concurrent experiments. Per the docs, this isn't possible in universal analytics (although I supposed we could add a second experiment dimension), but it should be possible in GA4, as it doesn't seem to have the new limits. We're in the process of setting up GA4, but it's not clear to me how we can run concurrent experiments? Does anyone have any suggestions or resources for how to do so? I've looked for documentation, but not seeing anything so far. Thanks!

Hi! Quick question related to metrics and

conversion window

parameter: if I set up this

conversion window = 48 (hours)

, in a binary variable as an example, what would happen is: • All the distinct users assigned to the experiment in the

Experiment Assignment Query

will be counted in the denominator. • Just the users with a conversion, with a timestamp falling in the conversion_window (

experiment assignment timestamp

+ 48h) will be counted in the numerator. However, there will be some users added into the denominator, which still have time to conver (imagine they just joined the experiment, they still have 48h to convert). This means that the metric will not be matured until 48h after of finishing the experiment. Is this reasoning correct? Many thanks!

I just created a dimension but it is not available for me to select in in the experiment results. Do I need to add it to the experiment itself somehow? I could not find it a place there so I assumed that after I created I could just use it
