Yes, we support React Native with our React InstantSearch library.

Make sure you update to version ^2.4.0 as we have improved our serialization strategy and should have solved all issues.

You need to subscribe to errors first. Try and subscribe to the searcher’s errors to figure out what is going on. There could, for example, be serialization issues.

searcher.error.subscribePast {
    Log.i("e", it.toString())
}

There’s a slight delay because events are sent in batches. This batching reduces the number of requests and network traffic on mobile devices. You can change the batch size if you need to. Larger batch sizes mean that there will be some extra processing on the server, so it could take a few extra minutes for events to appear. If you wish, you can also enable logging for more visibility of when events are sent.

To monitor the network requests, you can go to your Logcat and type HttpClient.

To see the currently applied filters, you can subscribe to the filterState like this:

filterState.filters.subscribe {
    val filterString = FilterGroupsConverter.SQL(it.toFilterGroups())
    Log.i("filterState", filterString ?: "" )
}

To display a banner, you need to listen to the searcher’s result update, extract the userData which contains the banner information, and then use that information to update your UI.

searcher.response.subscribePast { response ->
    val msg = response?.userDataOrNull?.firstOrNull()?.getPrimitiveOrNull("promo_content")?.content
    // display msg in a banner if it is available
}
