Hi is it possible to update feature definition without using webhooks?

how do you mean update? are you caching the features json?

No I mean if we setFeatures in GB constructor and after that I update some variation on GB dashboard then how it will effect in sampling? One option is to set feature again and in product code. But is there any other auto way?

you can update the context at any time with another call to

setFeatures()

but how I came to know there is some change in variations and needs to update context?

if you don't want to use webhooks, you could just Poll every x minutes, or adjust the TTL on your feature cache

Poll means to use setinterval?
