Based on previous feature flagging systems we've built, we assumed we'd probably just evaluate all flags at the same time on our backend, providing everything from a single API method It seems like growthbook's SDKs are designed to evaluate more on the client-side, at the point a flag needs to be checked Is there a reason we shouldn't just evaluate them all at the same time?

Hi GB team, how to define a target group of users with simple rule? I’m looking for a list of user uuids with OR relationship but it seems only AND relationship is offered. Do I have to use mongo query syntax in this case?

Does growthbook a/b testing work with React server side rendering? I found client side rendering example using CSR but couldn't find anything about SSR. https://dev.to/jdorn/ab-testing-with-create-react-app-53fg Also docs don't mention anything about it. https://docs.growthbook.io/lib/react

Is there a demo site running growthbook for a/b testing with react?

Hello, I’m just beginning with GB and here’s what I have done so far.

define("FEATURES_ENDPOINT", '<https://cdn.growthbook.io/api/features/key_prod_5926******fdba>');
$apiResponse = json_decode(file_get_contents(FEATURES_ENDPOINT), true);
$features = $apiResponse["features"];

// generate 100 fake requests and allow specific feature based on ID attribute.
for($i = 0; $i<100; $i++) {
    $growthbook = Growthbook::create()
        ->withFeatures($features)
        ->withAttributes([
            'id' => rand(1, 100)
        ]);
    if ($growthbook->isOn("test-feature-ab")) {
        echo "It's on! <br>";
    } else {
        echo "It's off :( <br>";
    }
}

Its working fine, I’m getting

On

and

Off

for specific set of users and its totally random. now, the question is that how can I feed those On/Off to the experiments, so that I can get report and statistics. Note: I’m using PHP SDK.

Hi! excited to get going with growthbook. reading the basic react example, just want to validate my understanding. in the example we're loading the features at runtime, so if some page that uses a feature is rendered before that effect runs (i.e. if we start from that page or statically render it with Next.js) we will end up rendering with whatever fallback we provide? reading the code doesn't seem like

useFeature

is subscribed to updates so it won't re-render after

setFeatures

is eventually called (which might be correct anyway so we don't flicker). wondering how y'all think about this, for static pages like that is the intent that we just bundle the features with our app? and for pages where we do want the feature to load from the growthbook api in the rendering path we just make sure the features are loaded before rendering?

Question, from the looks of it the

features

list is read in an effect (React SDK). So in theory if I wanted to do more live feature/ a/b testing I could wrap this in a poller for example. I don't think I would need something as extreme as web sockets for realtime changes just yet.

I guess part of and second question is that when setting attributes does that re-query the api for features that match. For instance if I write feature sets based on company and a user switches account (presuming they have multiple) then calling

setAttributes

would I then need to manually re call the api or is that part of the async action from setAttributes

I really like the rules based features. The chaining of rules is most interesting. Being able to target customers and then further segment features based on other attributes is very nice. No more (a && b && c && d ? thing : null)

Hello GB team. I'm trying to setup an experiment analysis using Growthbook and I have a question. One of the metric that we're tracking (customer's engagement score) does not seem to map to one of the metric types available (binomial, count, duration, revenue). This score is basically our own formulation of how engaged a customer is with our product, which takes into account multiple things (usage frequency/magnitude, social media engagement, support/feedback, etc) and it's a number between 0 and 1. We then run experiments to see the effectiveness of certain features in lifting that score and I'd like to see if I can analyse the experiments using Growthbook. Do you have any suggestion on how I should set this metric in GB?

HI all, Just starting to play around with the SDK’s. They are pretty easy to get up and running, but none of the examples are for server side features. Are they any example implementations against things like an node or expressJS server that shows best practices for refreshing the features list?

Hello! I've got a few questions about the experimentation features. We're trialing GrowthBook right now and have an A/A test going on. While the SDK has been great so far (Ruby), I have a couple issues I'm running into on the analysis side: 1. When I check the assignments table, there's ~50/50 split between variations. However, in the UI I see a 100/0 split. 50/50 is actually what I want but I'm confused about why the UI doesn't match. 2. When I try to pull in results, nothing comes up. However, the query for the experiment metric works as does the experiment for pulling identifiers. Any ideas on what might be causing these issues?

Hello all. I am trying to set up growthbook on a ec2 instance (ubuntu). Everything seems to work correct when I run docker-compose. however when I try to access the web page I get the following error

Not sure if I am missing something. Any help would be much appreciated

Hello everyone, first time here. Just starting out with Growthbook, i'm trying to set up Mixpanel as a data source but can't authenticate.. I'm sure about every field in the form except the username. Which name should it be? I tried my email & the name I entered but still can't authenticate. I'm logging in to Mixpanel via Google, does it matters somehow?

Hello 🙂 just joined here and I’m interested in exploring using growthbook in some parts of our Experimentation platform at Wolt. I’ve checked the docs but I’m particularly interested at first in taking advantage of the metrics part, using the python sdk. Any additional materials that could help me get started? Thank you!

Hey everybody! I am just starting, and it would be great to have some standard DB Schemas for AWS Athena (or any for that matter). I am a bit confused on a format I need to put data into our database in order to allow GB to query from it to perform A/B Experiments analytics. I know that I can write any SQL queries, but some default database structure would be super helpful.

Hey all 👋! I was wondering if someone has used GrowthBook for Shopify?

Hey! Just joined and evaluating using GrowthBook. We develop JS snippets that run on client Shopify stores. It's important that we keep bundle-sizes small & load the app quickly. Can anyone share info on • Growthbook react bundle size • Growthbook pure JS SDK bundle size • How much time growthbook adds to application start time

Hi Everyone! I was just evaluating GrowthBook and have a couple of questions: 1. Is there any support for edge experimentation i.e. integration with Fastly Compute@Edge? 2. Is there an option to configure some JSON or other payload for individual buckets? Thanks very much!

I’ve just hosted Growthbook on AWS ECS. Previously I had created a few metrics / experiments when I was running the container locally, and had the local container pointing to a remote Mongo DB. When I moved to ECS, I’m noticing requests to the

/organization/definitions

API endpoint fail, and I’m seeing this in the container logs:

Unexpected end of JSON input\n at JSON.parse (<anonymous>)\n at Object.decryptDataSourceParams (/usr/local/src/app/packages/back-end/dist/services/datasource.js:29:17)\n at Snowflake.setParams (/usr/local/src/app/packages/back-end/dist/integrations/Snowflake.js:11:36)\n at new SqlIntegration (/usr/local/src/app/packages/back-end/dist/integrations/SqlIntegration.js:17:14)\n at new Snowflake (/usr/local/src/app/packages/back-end/dist/integrations/Snowflake.js:9:1)\n at Object.getSourceIntegrationObject (/usr/local/src/app/packages/back-end/dist/services/datasource.js:69:15)\n at /usr/local/src/app/packages/back-end/dist/controllers/organizations.js:128:50\n at Array.map (<anonymous>)\n at /usr/local/src/app/packages/back-end/dist/controllers/organizations.js:127:38\n at Generator.next (<anonymous>)\n at fulfilled (/usr/local/src/app/packages/back-end/dist/controllers/organizations.js:5:58)","type":"Error","msg":"Unexpected end of JSON input"}

Per the docs I set

NODE_ENV

to

production

, and set a

JWT_SECRET

and

ENCRYPTION_KEY

. Could the fact that I saved the experiments without an encryption key when developing locally, and am trying to read those experiments in prod, be part of the issue?

metric definitions and other parts of the Growthbook prod UI work great

Hello, I'm trying to use Growthbook on my nextJs project. I followed this example and it's working great. However, I'd like to know if it was possible to get all features a given context is eligible to (in the react/js sdk)? I'm trying to find a way to pregenerate all variants at buildtime. Example: I have a

/test/

page and several Features, some of which have conditions like

page-path=/X/

and I'd like to pregenerate all variant who should apply to my given page. The rewriting / redirection would be done on runtime using next12 middlewares exactly like in the example. Thanks in advance

@future-teacher-7046 Hi, i has one issue: when I set

forceVariation

, and then i use

useFeature

, i expect to get the force variation value, but i found it returns me the default value, not the forced variation value, then i check the source code. i found in line 353: here the

res.inExperiment

is false. is this a bug? or how can i get the forced variation value?

Hey everyone, I'm trying to set up GrowthBook on a Next.js app with Mixpanel.

The thing is, I'm using a middleware for A/B testing, and I'm not exactly sure how to get the Mixpanel distinct id in this middleware, or even if I can access it.

He team , im looking to start and integrate growthbook with BQ . If i understand the docs correctly i need to create a custom schema ? https://docs.growthbook.io/app/datasources#custom-schemas

Hello!! I'm having trouble configuring the webhook to upload on s3. When I configure the webhook I get the response: "POST returned an invalid status code: 412" I'm using the endpoint: https://MYBUCKET.s3.amazonaws.com/ I have the variables enabled in docker-compose: AWS_ACCESS_KEY_ID = <ID> AWS_SECRET_ACCESS_KEY = <SECRET> S3_BUCKET = <MYBUCKET> S3_REGION = us-east-1 UPLOAD_METHOD = s3 S3_DOMAIN = <https://MYBUCKET.s3.amazonaws.com/>* I don't know if I need to enable the S3_DOMAIN variable but it is enabled When I test a PUT via POSTMAN I can upload it normally with AWS credentials.

How could I debug this?
