How Frontend Communicates with Backend | JavaScript + Axios Project

In this video, I demonstrate a simple yet practical Frontend + Backend JavaScript project designed to explain how real-world applications communicate between the client and server.

What this project covers:

• I create a custom backend API from scratch
• The backend returns a structured array of data (name, city, roll number)
• The frontend consumes this API using Axios
• The fetched data is displayed cleanly on the UI
• Proper error handling is implemented and explained, including:

API errors

Network failures

Invalid or unexpected responses

Why this project matters:

This project focuses on core engineering fundamentals that are essential in production-level applications:

Clear separation between frontend and backend

Reliable API communication

Graceful handling of failures instead of silent crashes

Clean, understandable code structure suitable for scaling

Rather than focusing on complex frameworks, this video emphasizes clarity, correctness, and best practices, making it ideal for:

Beginners learning full-stack development

Developers strengthening their API integration skills

Students preparing for real-world projects or interviews

Anyone who wants to understand how frontend and backend systems work together

Technologies Used:

JavaScript

Backend API (custom-built)

Axios for HTTP requests

Basic frontend rendering

If you are looking to build a strong foundation in web development and full-stack engineering, this video will give you a clear, practical starting point.
