Hi there! I'm trying to run growthbook on my Kubernetes without success 😅 I've managed to run it locally, but when I move everything to my remote environment it's not working. I opened a issue but probably should've asked here first. Can you guys take a look? https://github.com/growthbook/growthbook/issues/1045

I have a few other questions maybe you can help me with: • In the sdk there's

gb.loadFeatures({ autoRefresh: true })

: how long it takes to auto-refresh. • There's the GrowthBook proxy application. When it's recomended to use? ( Is there a request number recommendation?) • The Proxy docs says real-time feature rollouts. Without proxy it's not real-time?

Hi there! We are trying to deploy the solution to Azure, is there a step by step guide? We tried many things but couldnt make it work properly. Getting a ERR_CONNECTION_TIMED_OUT. (First time using docker, really basic knowledge)

Hey! I was wondering if anyone tried implementing Growthbook while using Varnish in front of the application server, whilst keeping the logic server side, I’m having trouble to conceptualise it.

Hi, I am using react SDK and I have set up the experiment and the GA connection. I am also able to get the feature value but it seems like the

trackingcallback

function is not being called. I am sending an event to GA and also using console.log in the

trackingcallback

. Is there something I can do ensure it runs smoothly ?

Hello, we are also planning on implementing GrowthBook for our Cloud functions (running in node.js). We have successfully using this on our front end (nuxt.js) and REST API (expressjs). For this Cloud function implementation, I would be happy to hear if every function invocation should use its own GrowthBook client or if we can cache the client for every instance instead? If so we could benefit

autoRefresh

on features as those could be refreshed until the instance is shut down rather than fetching them seperately for every invocation. Any ideas or suggestions to make it perfect with this type of server implementation?

Hello, has anyone tried to connect to the SDK with a React on Rails app? From the docs, I see that you need to wrap your app with the

GrowthBookProvider

component but how can I do so with a React on Rails app? I’m trying to connect the frontend to the SDK

What might be the reason not being able to add predefined metric to existing feature/experiment setup?

Hello! New to growthbook (and experiments in general), so new that I'm concerned I may screw up my first experiment run. Is it possible to run experiments with retrospective data if I set the experiment phases to be in the past?

Hi, can we export Mixpanel cohorts to GrowthBook so we can create feature flag conditions for different cohorts?

Hiya, I’m trying to get GrowthBook to send experiment data to GA4 from a React app (create-react-app) on localhost, with GrowthBook also locally hosted. GA4 is seeing regular events but following the GB tutorial isn’t working, probably because I’m using Google Tag Manager and I guess it’s different? I used the recommended code in index.html:

Copy code

<head>
  <!-- Google dataLayer variables -->
  <script>
    window.dataLayer = window.dataLayer || [];
  </script>
  <!-- Google Tag Manager -->
  <script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
            new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
          j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
          '<https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f)>;
  })(window,document,'script','dataLayer','GTM-xxxxxxxx');</script>

Copy code

<body>
<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="<https://www.googletagmanager.com/ns.html?id=GTM-xxxxxxx>"
                  height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>

Based on the GB tutorial I’ve put this in index.js:

Copy code

window.growthbook = new GrowthBook({
    apiHost: "<http://localhost:4100>",
    clientKey: "sdk-xxxxxx",
    enableDevMode: true,
    trackingCallback: (experiment, result) => {
        // TODO: Use your real analytics tracking system
        console.log("Viewed Experiment", {
            experimentId: experiment.key,
            variationId: result.key
        });
        // track using GA4
        if ("gtag" in window) {
            window.gtag("event", "experiment_viewed", {
                event_category: "experiment",
                experiment_id: experiment.key,
                variation_id: result.variationId,
            });
        } else {
            console.log("no gtag");
        }
    }
});

GrowthBook is working in the app; I created a feature in GrowthBook and can test for it in the app and display different UI 🙂 but the above always logs “no gtag”, and also it only runs once, on page load. Has anyone used GrowthBook with Google Tag Manager?

Hi, I am using Next.js middleware for the implementation i.e. Both feature flags and A/B testing based on this article https://dev.to/jdorn/ab-testing-with-the-new-nextjs-12-middleware-54j6. is there a way to use/enable feature flags to render elements or components in the frontend since all the implementation is done in middleware.

Morning @here. We just kicked off our first A/B test using growthbook, but we are getting these errors under the experiments > results. I’m not able to find any documentation to assist in the diagnosis. Can anyone help us? Thanks!

Hey 👋🏿 ! We’ve been using GrowthBook for a while now, and for the first time we’re faced with a SRM on one of our A/B test, we’ve checked the implementation, and don’t figure out what’s wrong.

Hello there! Is there a webhook for experiment callbacks so we can record that data directly in Snowflake or do we have to go through an event tracking service like Rudderstack?

I am trying to test growthbook with NodeJS on server side, but I am getting this error when compiling my TypeScript code with

tsc

Copy code

I have created a class to abstract growthbook for the rest of my application like this:

Copy code

import { GrowthBook, setPolyfills } from '@growthbook/growthbook';

setPolyfills({
  // Required when using built-in feature loading and Node 17 or lower
  fetch: require("cross-fetch"),
  // Required when using encrypted feature flags and Node 18 or lower
  SubtleCrypto: require("node:crypto").webcrypto.subtle,
  // Optional, can make feature rollouts faster
  EventSource: require("eventsource"),
})

class XPlat {

  provider: GrowthBook;

  constructor() {
    this.provider = new GrowthBook({
      apiHost: "<https://cdn.growthbook.io>",
      clientKey: "my-key",
      enableDevMode: true,
    });
  }

  isOn(name: string): boolean {
    return this.provider.isOn(name);
  }
}

export const xplat = new XPlat();

I am using

NodeJS

v16.15.1 . I have also tried compiling it with

NodeJs v18

and upgrading

@types/node

to the latest version, but I keep getting the same error. Any idea how to fix this?

Is there any example, or documentation, of how to use Growthbook as a singleton, to be used for FeatureFlags for a microservice, instead of creating a new instance in every request?

Hello Everyone, I am struggling to connect Growthbook with postgres. I am not able to see metric results on the same. Is there any documentation around this? I am using Go SDK to fetch experiment results but I am not getting any metric when I run my code

Copy code

func main() {
	growthbook.SetLogger(&growthbook.DevLogger{})
	featureMap := GetFeatureMap()
	features := growthbook.ParseFeatureMap(featureMap)

	context := growthbook.NewContext().
		WithFeatures(features).WithTrackingCallback(func(experiment *growthbook.Experiment, result *growthbook.ExperimentResult) {
		log.Println("Viewed Experiment")
		log.Println("Experiment Id", experiment.Key)
		log.Println("Variation Id", result.VariationID)
	})
	gb := growthbook.New(context)
	
	gb.WithAttributes(growthbook.Attributes{
		"user_id":       "123",
		"loggedIn":      true,
		"experiment_id": "123",
	})
	if gb.Feature("test-feature").On {
		// Feature is enabled!
		fmt.Println("TEST FEATURE 1 IS ON AND WORKING")

	} else {
		fmt.Println("TEST FEATURE 1 IS OFF AND NOT WORKING")
	}

Hey Hi all! I have a doubt while running an experiment from my sdk I get following logger

[INFO] Skip rule because user not in experiment: test-feature &{{map[loggedIn:true]} 0x140000aa1e0 <nil> [true false] 0x1400009a190 [0.5 0.5] <nil> 0x1400009a1a0}

How to ensure that user is in the experiment?

Hello everyone, Does the GrowthBook work well with HTML directly? I'm concerned that the guide doesn't have about it, only the frameworks.

Hi, I can’t get GrowthBook to find metric or experiment results from BigQuery (using GA4). I would be very grateful for any help as I’ve been struggling with this all week and can’t see what I’m doing wrong! I have a webpage with a button that sends an event “Main CTA” when clicked, and a feature “new-main-panel” which determines which version of the UI the user sees (both have the button). GA4 events are logged as per GrowthBook instructions and connected to BigQuery. I can see the events in BigQuery and they look correct. GrowthBook can connect to BigQuery; but my metric, after a brief blip, is showing nothing and my experiment has no data. BigQuery table: my onclick event that I’m measuring is “Main CTA”, and on login I’m setting user_id. I’m also sending the experiment_viewed event and that looks OK too. I can’t see anything wrong in the BigQuery data, see an example below: Metric: the SQL looks OK, it’s looking for the event “Main CTA”, see screenshot. But when I run the metric query, it only goes to 15 March and shows no data for the last few days, see screenshot. This is the full metric query:

SELECT

user_id,

user_pseudo_id as anonymous_id,

TIMESTAMP_MICROS(event_timestamp) as timestamp

FROM

``analytics_xxxxxx.events_*``

WHERE

event_name = 'Main CTA'

AND _TABLE_SUFFIX BETWEEN '{{startYear}}{{startMonth}}{{startDay}}' AND '{{endYear}}{{endMonth}}{{endDay}}'

My experiment based on this metric is running without error but showing no data. I must be missing something really simple…it’s so close to working! But I can’t think of anything else to check.
