## Guide New to Firebase or Next.js? No worries! Follow this easy, step-by-step guide to set up Firebase Authentication in Next.js app using the **next-firebase-auth-edge** library: https://hackernoon.com/using-firebase-authentication-with-the-latest-nextjs-features ## Docs The official documentation is available here: https://next-firebase-auth-edge-docs.vercel.app ## Why? The official `firebase-admin` library depends heavily on Node.js’s internal `crypto` library, which isn’t available in [Next.js Edge Runtime](https://nextjs.org/docs/api-reference/edge-runtime). This library solves that problem by handling the creation and verification of [Custom ID Tokens](https://firebase.google.com/docs/auth/admin/verify-id-tokens) using the Web Crypto API, which works in Edge runtimes. ## Features `next-firebase-auth-edge` supports all the latest Next.js features, like the [App Router](https://nextjs.org/docs/app) and [Server Components](https://nextjs.org/docs/app/building-your-application/rendering/server-components). To make adopting the newest Next.js features easier, this library works seamlessly with both [getServerSideProps](https://nextjs.org/docs/pages/building-your-application/data-fetching/get-server-side-props) and legacy [API Routes](https://nextjs.org/docs/pages/building-your-application/routing/api-routes). ### Key Features: * **Supports Next.js's latest features** * **Zero bundle size** * **Minimal setup**: Unlike other libraries, you won’t need to create your own API routes or modify your `next.config.js`. Everything’s handled by [middleware](https://next-firebase-auth-edge-docs.vercel.app/docs/usage/middleware). * **Secure**: Uses [jose](https://github.com/panva/jose) for JWT validation, and signs user cookies with rotating keys to prevent cryptanalysis attacks. ### What's New Key updates in latest release include: * Added `removeServerCookies` method to handle logout from inside Server Action * Added `experimental_createAnonymousUserIfUserNotFound` option to create anonymous user if no user was found * Full Firebase Emulator Support. The library now fully supports the Firebase Emulator, enabling you to run your development app without needing to create a Firebase Project. Follow [starter example README](https://github.com/awinogrodzki/next-firebase-auth-edge/tree/main/examples/next-typescript-starter#emulator-support) for details * Custom token is now optional. To enable custom token support use [enableCustomToken](https://next-firebase-auth-edge-docs.vercel.app/docs/usage/middleware#custom-token) option * Support ESM, Browser and Node.js imports for better tree-shaking features * Support for **Node.js 23** and **NPM 11** * Support for **Next.js 15** * Support for **React 19 RC** * New `experimental_enableTokenRefreshOnExpiredKidHeader` option in `authMiddleware` and `getTokens`, which refreshes user tokens when Google’s public certificates expire (instead of throwing an error) ## Installation To install, run one of the following: With **npm** ```shell npm install next-firebase-auth-edge ``` With **yarn** ```shell yarn add next-firebase-auth-edge ``` With **pnpm** ```shell pnpm add next-firebase-auth-edge ``` ## [→ Read the docs](https://next-firebase-auth-edge-docs.vercel.app/)
