@happy-autumn-40938 can clarify - I believe the autoRefresh supports server send events so updates can happen real time even for single page apps- but for the cloud that has to be enabled for your SDK by us currently. We’re just making some changes to the CDN which should allow us let users enable this for their own SDK endpoints.

ohhhhh that’s amazing, that’s the missing piece of the puzzle, thank you so much! Currently moving over from optimise (shiver) to GrowthBook and loving it btw

like Graham said, it's basically a prerequisite for using streaming updates (SSE). This is enabled for a few beta customers on Cloud currently, but soon all pro + enterprise customers will be able to turn it on per SDK Connection. There are some nuances about how to effectively subscribe to SSE when in a Node/backend context. We'll try to improve the docs and examples for this soon. Meanwhile, happy to explain further if you'd like.

Thank you @happy-autumn-40938, appreciate this! Sorry for the delay, have been away. No need to explain for now because we don’t need autoRefresh but would be amazing for it to be a bit clearer in the docs for the future
