Hi! How to view logs ("feature audit logs") in the self-hosted free Growthbook?

Hi all, I see that one of the data sources options is postgresql. I’m just starting out and will be fine creating a new db and putting data into it. Is there a guide as to what the schema should be and how I should connect GrowthBook to that new db?

Hi all, Is it possible to create multiple organizations in GrowthBook selfhosted? I don't see any option for this in settings or in documentation.

Hi all! If we enable the SDK from the front, the front needs a token for authorization in GrowthBook. It's right? Are there any recommendations on how to safely transfer this token to the front, and is it worth transferring at all?

Hi i want to upgrade my growthbook on-prem to pro account in on-prem can someone from sales team can contact me

Hello, I am implementing GrowthBook here at RVOHealth. The nextjs example program was successfully retrieving test features (

feature1

and

feature2

) from my cloud hosted GrowthBook app a few days ago but it fails to retrieve them in this morning. No changes have been made. How do I trouble-shoot this issue?

Greetings! I am implementing Growthbook for a/b testing in a next13 environment that deploys to Vercel. Currently the plan is to utilize edge middleware to handle rewrites to variant pages in a fashion similar to the Vercel Optimizely demo repo. The middleware is currently "working" in that based on which group I'm bucketed into I see the correct rendered page content. Unfortunately it's also broken in the sense that my

$experiment_started

events in mixpanel never show up. I have verified that

trackingCallback

in the middleware is being fired so I'm not clear as to what's happening. At some point I thought that maybe the middleware was completing before the call to mixpanel could actually fire so I wrapped the

mixpanel.track

into a promise that resolves itself in a callback passed to

mixpanel.track

and then added

NextFetchEvent#waitUntil

on the promise in question. This should have ensured that the middleware waits on the promise to resolve before moving on but unfortunately this had no discernible effect. I removed this extra complexity sometime yesterday prior to writing this message so it's not reflected in the pastebin example. At this point I'm not sure what else to try other than maybe plug in some other library for tracking. This is my first time using both Growthbook and Vercel middleware so it's totally possible that I'm doing something naïve. I hope that's really the case! For context I've included the contents of the middleware in question below.

lib/growthbook/features.json

is populated at server start and as part of the build process. https://paste.laravel.io/4d138b7e-7f96-4ce2-b074-d837ae2d9900

Hello everyone! Do you recommend any tutorial to do my first AB test with reactJS, with self-hosted GB? I’m having a hard time understanding the conversions. I am using

postgres

for the datasource and currently I have only one table (

viewed_experiments

), I have not found information regarding the database schema that should be used. thnks

Hi everyone, I need some help to initiate the growthbook project with vanilla nodejs. So, I iniciated a NodeJS (v18.12.1) empty project to test the GrowthBook tool.

mkdir test
cd test
npm init -y
npm install --save @growthbook/growthbook
touch index.js

inside

index.js

file, I paste the Step 1 from the guide (https://docs.growthbook.io/lib/js)

import { GrowthBook } from "@growthbook/growthbook";

// Create a GrowthBook instance
const gb = new GrowthBook({
  apiHost: "<https://cdn.growthbook.io>",
  clientKey: "sdk-key",
  // Enable easier debugging of feature flags during development
  enableDevMode: true,
});

// Wait for features to be available
await gb.loadFeatures({ autoRefresh: true });

const color = gb.getFeatureValue("button-color");

When I executed

node index.js

, the terminal yield

(node:38068) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
./tmp/test/index.js:1
import { GrowthBook } from "@growthbook/growthbook";

Then I add this line to

package.json

"type": "module",

And run again the code. This time the error message was this

./tmp/test/index.js:1
import { GrowthBook } from "@growthbook/growthbook";
         ^^^^^^^^^^

And then, I change the

index.js

file to this

import pkg from '@growthbook/growthbook';
const { GrowthBook } = pkg;

// Create a GrowthBook instance
const gb = new GrowthBook({
  apiHost: "<https://cdn.growthbook.io>",

  // Enable easier debugging of feature flags during development
  enableDevMode: true,
});

// Wait for features to be available
await gb.loadFeatures({ autoRefresh: true });

const color = gb.getFeatureValue("button-color");

And run the nodejs file again. This time I received this error message:

Can get any help?

Hi @fresh-football-47124 I see your team has been merged code changes into master for Flutter SDK. So, when we will get for next version release of GB for Flutter? Thanks.

Is not there a JavaScript A/B test guideline in GrowthBook using only client side vainilla JavaScript in or I'm missing something?

Hey are you planning to include a way of updating the value of a feature flag in the sdk for JavaScript? Something like:

gb.updateFeatureFlag('feature-flag-key', true);

This message was deleted.

Hey bit of a weird question but is it possible to analyse A/B experiments on request level? Scenario: we have our own A/B experiments set up via traffic shifting but instead of sessions or users we solely run experiments on request level, would it be save to substitute user_id with request_id in that case if we only want to onboard growthbook for experiment analysis?

Hey guys ! Happy to join your community I’m here with @brainy-belgium-16036 and we are working on the integration of growthbook in our stack (self hosted). We got the feeling from the documentation that we were supposed to have only one instance (or one load balanced cluster) of the proxy for our growthbook instance. Is that the case or could we potentially have one proxy per environment ? This would enable us for example to run the proxy for our local development environments.

Besides, there is one more issue that we faced. We deployed the app on one of our servers and it worked properly for a couple of weeks but after that it's giving timeout. We even tried starting it again but no luck still timeouts. Any suggestions please??? Thanks in Advance

Hi We have started using GB recently, but I can not get the results from the experiments to show. It is stuck on "No data yet. Click the "Update" button above." We are self hosting GB. However I also have it set up on my local machine with the same metrics and experiment, and there I do see the results. I have checked the query and it is working. The results are also stored in our mongoDB. Finally I do get to see the graphs for the metrics so there does not seem to be a general problem with the rendering of graphs. I can not see any error messages that would help narrow down the problem Is there anything else I should try?

Hello team! I’ve been struggling with deploying GB on remote server with docker (+ docker compose). Seems like it’s due to misconfiguration of

API_HOST

or

APP_ORIGIN

- yet I’ve tried all kinds of url but had no luck. Could you help me please? Thanks

Hi, We have just started integrating GB but I have a slight confusion. I am trying to connect GB to GA v4 but it asks to "upload key file". I am confused about whether this is the same key file that's generated as per this tutorial or something different?

Hey, We're trying to integrate Growthbook into a Nuxt.js app with anonymous users only. We currently use full page HTML cache in our CDN hosting service (Fastly), and we need to run Growthbook server side. The full page cache will not work with our current solution in which we use cookies for the

localStorage

polyfill, and to persist the random ID used as

id

in the

setAttributes

function. We would like the find a solution where the full page cache will only cache the various combinations of Growthbook variations, and not cache for every unique user. Do you have an ideas as to how we can solve this?

Hi, I’m still testing GB and now I’ve come across the following: I need to get variation_id before the trackingCallback is executed, is there a way to do this with the react SKD?

Hey team! 👋 We've recently started integrating Growthbook into our infrastructure, and we're facing a dilemma regarding how to support common flags across multiple services and apps. While creating SDKs bound to 'All Projects' is an option, we're concerned that the configuration file might grow too large, which could affect the performance of the client apps. Another approach we're considering is creating a gb-project for each service, with a shared project that will host any common flags. However, we'd like to be able to connect an SDK with multiple projects to support this scheme with one SDK per app. Currently, it's only possible to connect an SDK with one specific project or with 'All Projects.' Have you considered implementing this improvement? Thank you! 😊

Hey Team, Is there an example usage of FeatureMap available for reference?

Hello team and have a nice day. I use version 1.9.0 with "frequentist" in statistic engine setting. Frequentist is not like Bayesian, we must calculate the sample size before we really run the test or else, we will have type I and type II error. Please let me know where can I calculate the minimum sample size. Is there a function like that in Growthbook or we need to calculate by hand outside the platform?

If we use custom data source, for example mysql, what is the best pratice database schema do we need to prepare? What table and field need to define? Is there any document mention about that?

Hi! Could you please explain how Segments work? The query requires a

user_id

and a `date`: could you explain what the date is for? I could not find any documentation on it. From the FAQ I understand that this is mostly used to correct/filter experiments and limit them to a subset of

user_id

, but I cannot understand the role of the

date

column.

Hi! We just integrated Growthbook and are about to do our first AB tests. I understand that the Bayesian approach frees us from calculating a sample size and therefore the test duration and enables us to continuously monitor our AB tests and make faster decisions. BUT how do we know when to stop a test? Should we define appropriate stopping rules to help us draw conclusions quickly but safely? If yes, do you have any tips? Thanks a lot

Do we an api to create features on Growthbook?? I went through the docs but I only saw GET apis to fetch all the features

Hiya, thank you for letting me join the channel. I have a total newb question as I’m trying to run GrowthBook locally on a different port from 3000. With the default port all is good but if I change port then I see a “failed to fetch” error. I have checked the docs and can’t see my mistake. Here’s my docker-compose.yml:

version: "3"
services:
  mongo:
    image: "mongo:latest"
    environment:
      - MONGO_INITDB_ROOT_USERNAME=root
      - MONGO_INITDB_ROOT_PASSWORD=password
  growthbook:
    platform: linux/amd64
    image: "growthbook/growthbook:latest"
    ports:
      - "4000:3000"
      - "4100:3100"
    depends_on:
      - mongo
    environment:
      - MONGODB_URI=<mongodb://root:password@mongo:27017/>
      - APP_ORIGIN=localhost:4000
      - API_HOST=localhost:4100
    volumes:
      - uploads:/usr/local/src/app/packages/back-end/uploads
volumes:
  uploads:

Can anybody see where I’ve gone wrong? I’ve tried http://localhost:4000, http://127.0.0.1:400 for the environment variables but no luck. And I’ve searched the channel but not found this exact issue. Thank you!
