hi! I/we are thinking of building a Drupal Module, to integrate GrowthBook easily into Drupal™ DXP Open Source System. 1. is there some kind of reference with fields etc, we could have. It is not best practise in Drupal to directly have a text-long field to just paste the js. We would like to define the ID/url of the system on a settings page and add needed js automatically and have some other fields which defines other settings/values by defualt and maybe have settings per page too, whcih can be handled then via differnet users/permissions directly on the page etc. … settings for visual editor etc… Is there some kind of document/reference we can look at? 2. is there some kind of funding/support for such integrations? Here our Drupal company page as a reference of what we do 😛 https://www.drupal.org/acolono-gmbh

I was going to put together a helm chart, do you all have a public growthbook image I can use?

Hi all, we're looking for server-side experimentation platforms and I noticed a little blurb in your dev SDK about server-side support coming soon. Do you have any details on how fleshed out the concept is (couldn't find it in your public roadmap) and what that might look like?

Hi in my last chat with the team here the visual editor was being moved to a Chrome browser extension -- wanted to know if that's still priority for 2022

Hello everyone, we will need a server-side SDK for .NET. I didn't see one readily available so I took some time and created one. I have yet to put it into a NuGet package and release it but I basically used the python+JS versions (incl. tests) as a boilerplate and re-wrote it to C#. Granted my A/B testing knowledge is limited but having the great set of unit tests from the JS side certainly helped me build it with better confidence. Not sure if there is any interest out there for it, and we have yet to vet it or even use it in a deployed scenario yet. REF: https://github.com/richerm/growthbook-dotnet

Hi! I'm experimenting with using the optimizly sdk's with Growthbook. It looks quite straight forward. One basically needs a function that transforms growthbook config to an optimizely datafile. 1. Have anyone of you explored this idea before? Any gotchas to be aware of with this approach? 2. Currently, only overrides are exposed through the Growhtbook api. The optimizely datafile format requires more information than that, so currently I've just "hacked" the regular api by manually crafting an jwt token the same way the js app does, and uses the

/exeriments

endpoint to get all experiment configuration needed in one request. Would it be possible to add an

/experiments

endpoint that could be accessed with the api key one can generate in the UI?

Hi, why can't I see data preview for some metrics that have setup? I've setup 3 metrics and data preview is available only on one. No data is shown on the other 2. Attaching a screenshot of one of the metrics.

Hi, Im getting an error when trying to connect GA

Hi there, Just discovered Growth and I think it's great and I'm excited to start using it. I'm trying to implement it and I've run into a few snags. Any help would be much appreciated. Our App is freemium so people can use the core feature without needing to signup. This means that we don't always have user details when people use the app. I'm calling the Growthbook context as the app loads and fetching features as instructed in the docs here: https://docs.growthbook.io/lib/js

// Create a GrowthBook context
const growthbook = new GrowthBook();

// Load feature definitions (from API, database, etc.)
fetch("<https://s3.amazonaws.com/myBucket/features.json>")
  .then((res) => res.json())
  .then((parsed) => {
    growthbook.setFeatures(parsed);
  });

My questions are: 1. How does Growthbook know which feature to assign without knowing who the user is at this point? 2. If the user then creates an account and we use use

growthbook.setAttributes()

to update the id, will whatever anonymous tracking token that was used previously be merged into the new ID we give it when the user signups? 3. Our app also allows people to create multiple accounts and switch between them. If this happens do we have to refresh the data? I'm assuming

setAttribute

won't work here as we want to switch to an existing user id not update the existing user with a new ID. Any guidance or direction on how to think about and manage this would be much appreciated.

One more question to set things up. Everything is implemented now but none of the metrics are showing any data. We're using Mixpanel as a data source. There is;t too much documentation on how to do this, so I'm happy to add the documentation to the open-source repo once I figure out how to get it all working as expected. Created a service account for the connection. I'm not sure if I have set everything up correctly but it does say connected so I'm assuming this part is 👍

for the bigquery integration, is there a reason you're using

DATETIME

instead of

TIMESTAMP

here? we're currently needing to cast all of our timestamp columns to datetimes (not a huge deal, just a lot of boilerplate) https://github.com/growthbook/growthbook/blob/fba1913c12c41eb7e2b7f061f1e7f9184441ab98/packages/back-end/src/integrations/BigQuery.ts#L33-L35

when I called API

<https://cdn.growthbook.io/api/features/key_dev_xxxxxx>

, the result I got is

{
  "status": 200,
  "features": {
    "should-show-product-title": {
      "defaultValue": true
    }
  }
}

However, when I do

useFeature('should-show-product-title').on

, the result is false instead. So, what might be the root cause of these different results?

Another question is that if I just need simple feature type which is on/off, is

growthbook.setAttributes

still required programmatically?

@fresh-football-47124 What does the smaller value in gray mean for a duration based metric?

Is there a way to override the default variation IDs (0, 1) for experiment rules? E.g. using

blue-button

and

red-button

rather than

0

and

1

would make it simpler to distinguish between the different variants

hey guys, looks like you’re pushing some stuff rn but my features list got bugged

Hey guys, I’m hitting a bug in the UI. I’m adding an attribute to an experiment as a boolean “exists” and then it shows “does not exist” in the UI

Hey guys, looks like there is a maximum of 7 (8 - the experiment started event) metrics we can track per experiment with Mixpanel?

Separate question, I have a metric which is a duration metric which is currently calculating as the total time divided by all the ppl who started the experiment to show me the average, but I would like it to show me the total time divided by the number of ppl who triggered the event (e.g. in my case “Time To Assessment Completed”). How would I do that?

Hey appreciate the tags you guys added to the Features page!

Hey! Do you have a nice way of updating the attributes of a growthbook instance through the lifetime of a Nextjs app? I currently do it like this

export const useSetGrowthbookAttributes = (
  attributes: Record<string, string | number | boolean>
) => {
  const gb = useGrowthBook();
  useEffect(() => {
    gb?.setAttributes(attributes);
  }, []);
};

But would love to hear other ideas!

Hello Everyone! My name is Gabriel Sotomayor. I read about GrowthBook through Y Combinator. I thought it was a great product and wanted to contribute. I created a small PR for issue #154 . I'm early in my programming career, but happy to contribute in any way I can. :)

Hi! We just met a frontend bug and created a fix for this. Please help review it. Thanks~ https://github.com/growthbook/growthbook/pull/319/files

Hey guys, for the Mixpanel data source, would it be possible to also apply the User Dimensions to user profile properties, not only event properties? Right now to use the user dimensions it has to be a property of an event the user triggers, but some stuff like e.g. their current subscription status we don’t include on every event, but rather as a user profile property.

Hi Everyone, My name is Ali and I am software developer working in Norway. I came across grothbook while searching for A/B testing software. I wanted to contribute and I noticed that there wasn't any SDK for dotnet, hopefully I can finish it soon and contribute it to the official growthbook repo 🙂

Hi! What would be the best way to determine if a feature flag is disabled when fetching feature flags from the API (

<https://cdn.growthbook.io/api/features/[key]>

)? Is it safe to assume that

defaultValue

is always set to

null

for a disabled feature?

Hi, I am trying to use growthbook devtool in chrome where I am getting this

Error
Timed out waiting for GrowthBook SDK instance

is there any doc how to use chrome devtool for growthbook?

I have another question. Launchdarkly has realtime feature means, if I change the features flag value in their dashboard it's changed immediately in the client side. Is there same feature in Growthbook? if yes then how to achieve that?

Hey guys, I want to run a new A/B test, on a new set of users because the first test had some confounding factors, using the same tracking key. However I get a “duplicate tracking key” error. Am I not able to add a new experiment using the same tracking key?

Hey guys, a question and a request: 1. Question: We’re finding that we want to test the effect of a feature on new users, and existing users as two separate groups, since new users would never know what it was like before, and existing users have to adapt to the change. What is the best way to set this up as far as feature flagging and experimenting goes? Right now, I’m creating two separate feature flags (one for new users, one for existing), creating separate override rules for each as part of setting up the A/B test and then creating two experiments in the experiments list. This feels hacky, is there perhaps a better way to do this? 2. Request: In the experiments, results tab, in the metrics table, can we see the type of metric it is e.g. binomial or count or duration, etc.. Especially when we turn on “converted only” for a count metric, it means something pretty different than a binomial metric and my non-tech team members may get confused
