Motivation Behind the Project
The core motivation behind next-firebase-auth-edge lies in overcoming limitations posed by the firebase-admin library, which relies heavily on Node.js's internal crypto library unavailable in the Next.js Edge Runtime. The library resolves this constraint by creating and verifying Custom ID Tokens using the Web Crypto API, which is compatible with Edge runtimes.
Key Features
next-firebase-auth-edge boasts an array of essential features that enhance its usability and functionality:
- Latest Next.js Feature Support: It integrates with cutting-edge Next.js features like the App Router and Server Components.
- Zero Bundle Size: The library imposes no additional bundle size restrictions.
- Minimal Setup: Users do not need to create custom API routes or modify next.config.js, thanks to middleware handling.
- Security: Utilizes the
joselibrary for JWT validation and signs user cookies with rotating keys for robust security against cryptanalysis attacks.
Noteworthy Updates in v1.8
Version 1.8 of the library introduces several significant enhancements:
- The custom token feature has become optional and can be enabled via the
enableCustomTokenoption. - Improved import support for ESM, Browser, and Node.js for effective tree-shaking.
- Compatibility updates for Node.js 22, Next.js 15 RC, and React 19.
- A new
experimental_enableTokenRefreshOnExpiredKidHeaderoption, allowing automatic refresh of user tokens upon expiration of Google’s public certificates instead of error throwing.
