What is react-firebase-hooks?

React Firebase Hooks is a TypeScript library that makes it easier to use Firebase services inside React applications. Firebase is Google's platform for adding features like user sign-in, a live database, file storage, and cloud functions to a web or mobile app. React Hooks are a pattern in React that lets you share stateful logic across components without extra boilerplate. This library combines the two, giving developers pre-built hooks for common Firebase operations so they do not have to write the wiring code themselves. The library covers six Firebase services: Authentication (sign-in and user state), Cloud Firestore (the document database), Cloud Functions (server-side logic triggered from the frontend), Cloud Messaging (push notifications), Cloud Storage (file uploads and downloads), and the Realtime Database (Firebase's older live data store). For each service there is a corresponding set of hooks you import and call inside your React component, so a component can, for example, read live Firestore data and automatically re-render whenever that data changes. Installation is through npm or yarn with a single package. The library requires React 16.8 or later and Firebase v9 or later, since the current major version, v5, targets Firebase's newer modular v9 API. Earlier versions of the library that target older Firebase APIs, including one built for Firebase v8, remain available on tagged branches in the repository for projects that have not upgraded yet. The README notes that React Native Firebase support, which older versions partially had, is harder to guarantee under the v9 API and may be revisited later. The author describes the project as an evolution of an internal library the team used before React Hooks existed, saying the hooks based version is far simpler than what came before. The README links out to separate documentation pages covering each service's specific hooks in more detail. The project is open source and published on npm.
