Introducing RxFire: Easy async Firebase for all frameworks

RxFire is a JavaScript library that integrates Firebase’s realtime data services with RxJS observables, helping developers manage, transform, and combine asynchronous streams without relying on complex nested callbacks. It provides observable creation methods for Firebase Authentication, Realtime Database, Firestore, and Cloud Storage, allowing developers to apply RxJS operators such as filter, switchMap, mergeMap, and combineLatest to tasks like monitoring login state, synchronizing database lists, joining profile and cart data, and retrieving authenticated users’ storage files. Developed from lessons learned through AngularFire, RxFire is designed to work across frameworks including React, Preact, Vue, Stencil, Polymer, and plain JavaScript, while remaining a complementary layer rather than a complete Firebase wrapper. The library can also support lazy loading Firebase modules through dynamic imports and RxJS promise conversion, reducing initial application bundle sizes. Initially released in beta, RxFire is described as generally available for production use and is distributed through npm or Yarn alongside Firebase and RxJS peer dependencies.
