FAQs

I need help with [anything regarding <= v5 of React Native Firebase]. Where could I get help with that?

React Native Firebase v5 is now deprecated and unsupported. There's been over a year's grace period provided to migrate to v6, so moving forward maintainers probably won't pay much attention to issues regarding v5. Understandably, upgrading to v6 can take some effort, but staying on v5 probably isn't a great choice for the long-term health of your project. Lots of the breaking changes that were introduced were either due to upstream deprecations in the official SDKs, or to simply make the package more stable and more representative of how the actual SDKs work. The longer you stay on v5, the more your project will be out of sync with the official SDKs, unfortunately. Couple that with the fact that it's no longer actively supported, and that's trouble looming over the horizon for your project.

We highly recommend taking the necessary pains to update to v6.

My CI build hangs at the Running script '[CP-User] [RNFB] Core Configuration' step.

This may be fixed by creating a firebase.json file at the root of your project if it's not there already. If you don't want to change any of the default React Native Firebase configurations, you can leave it empty in the following way: 

{
  "react-native": {
  }
}

Tips

  • Advice on supporting multiple environments (for example, dev, prod, maybe also staging, qa) for your React Native Firebase App: #3504
  • Using Fastlane for iOS deployment together with RN Firebase Crashlytics within CI has been observed to cause builds that hang indefinitely. Using setup_ci(force: true) before building the application may solve the issue.: #3706
