Build a Todo App with the PERN Stack (PostgreSQL, Express, React, Node.js)
In this tutorial, we'll build a complete Todo App using the PERN Stack (PostgreSQL, Express, React, Node.js). You'll learn how to create a full-stack application with a React frontend, Node.js/Express backend, and PostgreSQL database. By the end, you'll have a fully functional Todo application with CRUD operations, modern UI, and responsive design.
✨ What You'll Learn:
How to set up a React frontend with modern hooks
How to create a Node.js/Express RESTful API
How to design a PostgreSQL database for a Todo app
How to perform CRUD operations (Create, Read, Update, Delete)
How to implement optimistic UI updates for better user experience
How to style components with Tailwind CSS
How to handle errors and loading states
How to connect frontend and backend effectively
How to test API endpoints with Postman
How to manage your database with pgAdmin
🚀 Key Features:
Full CRUD functionality (Create, Read, Update, Delete todos)
Modern React with hooks (useState, useEffect)
Responsive design with Tailwind CSS
Optimistic UI updates for instant feedback
RESTful API with Express.js
PostgreSQL database with proper schema
Error handling and loading states
Clean, professional UI
API testing with Postman
Database management with pgAdmin
