AuthCoreFramework-Agnostic Authentication

A Devise-inspired auth library for the JS ecosystem. Drop-in adapters for Express, Fastify, NestJS, React, Prisma, and more.

Framework Agnostic

Core logic has zero framework deps. Use with Express, Fastify, or any Node.js framework.

bcrypt passwords, SHA-256 hashed tokens, timing-safe comparison, no email enumeration.

Swap your database (Prisma) and email provider (Resend, Nodemailer) without changing app code.

AuthProvider, useAuth hook, and ProtectedRoute — works in API mode or cookie mode.
