AuthKit
Reusable authentication boilerplate with JWT, Google OAuth 2.0 via Supabase, role-based access control, and protected route middleware. Plug-and-play for any Next.js project.
نظرة عامة
AuthKit is a production-ready authentication boilerplate designed to be dropped into any Next.js project. It provides a complete auth system out of the box — JWT-based session management, Google OAuth 2.0 via Supabase, role-based access control with granular permissions, and protected route middleware that secures both pages and API routes. The goal was to eliminate the repetitive boilerplate of setting up auth for every new project and provide a battle-tested, secure foundation.

التقنيات المستخدمة
التحديات والحلول
Designing a middleware system that protects routes at the edge while supporting both page and API route protection — implemented using Next.js middleware with JWT verification at the edge runtime
Making the RBAC system flexible enough to support custom roles and granular permissions without over-engineering — solved with a permission matrix pattern that maps roles to route patterns
Ensuring secure token refresh without race conditions during concurrent requests — implemented with a token queue that serializes refresh attempts
