The update replaces browser-specific APIs used for authentication and fixes issues like persisting auth state across app restarts. Caveats remain: popup/redirect-based auth methods don't work in React Native, and Storage uploads are unsupported since File and Blob types aren't available (downloads still work). Separately, the release adds unauthenticated access to the Node.js SDK, letting apps initialize with just a database URL instead of requiring a service account, though a service account is still needed for creating and verifying tokens. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does Firebase JavaScript SDK 3.1.0 work with React Native again? Yes, Firebase JavaScript SDK version 3.1.0 restores React Native compatibility after it broke when the 3.x SDK launched at Google I/O. The release replaces browser-specific authentication APIs and fixes issues like persisting authentication state across app restarts, so initializing Firebase in React Native works the same way as in any other JavaScript app. _daily.dev helps mobile developers track SDK compatibility fixes like this Firebase and React Native update._ ### Why isn't Firebase Storage file upload working in my React Native app? Firebase Storage uploads do not work in React Native because the environment lacks the File and Blob types that the JavaScript SDK relies on for uploads. File downloads still work fine in React Native. This limitation persists even after the 3.1.0 SDK update that restored other React Native compatibility. _Developers debugging Firebase Storage quirks on React Native can follow fixes like this on daily.dev._ ### Can I use the Firebase Node.js SDK without a service account? Yes, as of Firebase JavaScript SDK 3.1.0, the Node.js SDK supports unauthenticated access, so you can initialize an app with just a database URL instead of a service account key. A service account is still required for creating and verifying tokens, and without one, database access is restricted like any unauthenticated client. _daily.dev keeps backend developers current on Firebase Node.js SDK authentication changes like this._ --- Tags: [#javascript](https://daily.dev/tags/javascript), [#nodejs](https://daily.dev/tags/nodejs), [#authentication](https://daily.dev/tags/authentication), [#react-native](https://daily.dev/tags/react-native), [#firebase](https://daily.dev/tags/firebase) [View this post on daily.dev](https://daily.dev/posts/firebase-and-react-native-mogludhgb) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Firebase and React Native","url":"https://daily.dev/posts/firebase-and-react-native-mogludhgb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/firebase-and-react-native-mogludhgb"},"datePublished":"2026-08-23T12:20:10.984Z","dateModified":"2026-08-23T12:30:39.555Z","description":"Firebase JavaScript SDK version 3.1.0 restores compatibility with React Native, which had broken when the 3.x SDK shipped at Google I/O.
