Using in conjunction with native SDK?

[iliaskarim]

Will the react-native-firebase framework work in conjunction with the native iOS Firebase SDK? For example, to make some calls from native and some from React Native.

It should yes. Be careful though, react-native-firebase has a strong expectation that it is in control of initialization for the apps in firebase-ios-sdk and you will run in to problems if you attempt to configure firebase-ios-sdk using non-react-native-firebase configuration mechanisms.

Instead, if your native code has any execution paths that touch firebase-ios-sdk prior to react-native-firebase starting up and initializing you should call the react-native-firebase initialization machinery to make sure it is set up internally and in a consistent state

This is not really something we support because no one really does it and the ones that do know what they're doing, although not always

@mikehardy thanks for your response. I'd like to start a performance trace on the React Native side and continue it on the native side. However, it doesn't look like that's possible with the framework.

That's not something I've ever heard of anyone trying, no, but it's software, anything is possible right? Especially given it's open source, there is usually a way to hack something in to node_modules code directly to try it, and if we need to make an interface more open or similar that's something that we'll take as a PR historically. I think perf is easier than modules like database or firestore when it comes to brownfield applications because they don't rely nearly as much on settings from plist/json being read and stuffed into the firebase module instances, so init issues may not be as tough to deal with. But you're definitely blazing trail on your own here...
