studio-ai-auth

studio-ai-auth

A reusable Next.js middleware package for authentication and token validation. This package helps enforce authentication across multiple micro-frontends without code duplication.

🚀 Features

👉 JWT Token Decryption & Validation 👉 Automatic Redirection to Authentication if token is missing/invalid
👉 Configurable Public Routes (Define accessible routes without authentication)
👉 Reusable Across Micro-Frontends (Reduce redundant auth logic)
👉 Easy Integration with Next.js Middleware

📛 Installation

Install the package using npm:

npm i studio-ai-auth

or using yarn:

yarn add studio-ai-auth

** Environment Variables**

Ensure you have the required environment variables set in your .env.local file:

PRIVATE_KEY="-----BEGIN PRIVATE KEY-----\nMIIEvQIBADANB...\n-----END PRIVATE KEY-----"
PRIVATE_KEY="-----BEGIN PUBLIC KEY-----\nMIIEvQIBADSZANB...\n-----END PUBLiC KEY-----"
KEYCLOAK_ISSUER="https://keycloak.example.com/auth/realms/my-realm"
KEYCLOAK_CLIENT_ID="my-client-id"

🗜️ How It Works?

1️⃣ Extracts JWT from Cookies
2️⃣ Decrypts & Validates token (expiration, issuer, audience)
3️⃣ Allows or Redirects the request based on validation
4️⃣ Handles Public Routes (Allows users to access without authentication)
