Hello Everyone, we started to experiment with the GrowthBook. We would not want the rules to be exposed to the frontend ReactJS app. Wondering if there is any server side sdk that we can use to return only results of features to the frontend growthbook library

You can use any of our back-end SDKs for that. Basically, you would need to create an API endpoint where you pass in user attributes. Then, you could loop through and evaluate all the features and return the results in the API response. Call that from your React app when you first load the page and you'll have all of the feature values. We're working on a Proxy Server soon which is a pre-built Docker container you can deploy on your infrastructure that handles all of that for you automatically.

Cool. wish there was a "proxy" sdk library instead of a docker so we can simply call into that sdk with facts (user attributes) and it spits out the growthbook client sdk compatible output

Making the proxy server a NodeJS library could make sense. We would still release a standalone Docker image version for people not using Node.
