growthbookusers #sdk-react

Hi all. i've been trying to set up Growthbook in Shopify's Hydrogen framework, which is based on Remix. I'm new to React so it is a bit of a learning curve, but I have followed these instructions: https://docs.growthbook.io/lib/react I am getting features through from GB and the tracking callback is being triggered abd I can see the experiment_viewed event in BigQuery. If I set a feature to be always on or off in GB my local site immediately updates. But my 50/50 experiment rule is always coming through as OFF (the first value). I have this:

Copy code

export default function App() {
  ...
      <body>
        <GrowthBookProvider growthbook={gb}>
          <Layout {...data}>
            <Outlet />
          </Layout>
        </GrowthBookProvider>
  ...
}

and then this:

Copy code

export default function Homepage() {
  ...
  const gbFeature = useFeatureIsOn("test-feature");
  console.log(gbFeature)
  ...
}

In another GB implementation it has not been an issue to see different feature values in different browser sessions (incognito windows for example). I am assigning with Google Analytics clientId and I can see this is set (by using the useGrowthBook() method to access GB instance directly), and that it is being set differently in different browser sessions. It is being set via a promise:

Copy code

useEffect(() => {
    // Set user attributes for targeting (from cookie, auth system, etc.)
    gb.setAttributes({
      clientId: getClientId(),
    });
  }, []);

which may mean the value is not available for assigning variation (getClientId awaits a promise). This may or may not be related though. I have got the same underlying approach working in Vue no problem, but may be missing something about React here. Thanks for any advice.

Hi, total newbie on GB. I have setup the account, incorporated the SDK into my code and created a feature with string value, but all I’m getting back is the default value. I can see the response from GB but then nothing further:

Copy code

{
  "status": 200,
  "features": {
    "title-text": {
      "defaultValue": "GROWTH BOOK LIVES!"
    }
  },
  "dateUpdated": "2023-10-27T12:24:24.615Z"
}

✅ 1

A further question arising from the above - why is the

trackingCallback

‘_required_’ for A/B testing? I’m struggling to see what I would be analysing.
