PERN Stack Authentication Tutorial | PostgreSQL, Express.js, React, Node.js
Build a complete Authentication System with the PERN Stack PostgreSQL, Express.js, React, Node.js!
In this step-by-step tutorial, you’ll learn how to implement secure user login, registration, and protected routes using modern authentication tools — JWT, bcrypt, and httpOnly cookies.
We’ll also use Postman for API testing and pgAdmin to manage and view user data directly in the PostgreSQL database.
🚀 What You’ll Build:
Full authentication system with register and login
Protected routes using JWT and middleware
Logout functionality with cookie handling
Frontend connection with Axios and React Router
Clean and responsive UI setup
💻 Technologies Used:
PostgreSQL + pgAdmin (Database & Management)
Express.js and Node.js for backend
React.js (Vite) for frontend
JWT and bcrypt for authentication
cookie-parser, Axios, and CORS (Communication & Security)
Postman (API Testing)
⭐️ Key Features Implemented:
User registration with password hashing
Login with JWT authentication
Token and cookie management
Route protection on both backend and frontend
API testing with Postman
Database setup and user management with pgAdmin
