Connect React Frontend to FastAPI Backend | Mini Issue Tracker – Part 7

Check Our Programs : https://reactivecodes.in/courses 🚀 The Mini Issue Tracker is finally complete! In this final part, we connect our React frontend with the FastAPI backend and test the complete application end-to-end. After building the backend APIs with FastAPI, SQLAlchemy and PostgreSQL, we now connect those APIs to the frontend using the Fetch API and make the complete Issue Tracker application work together. 🔨 What we build in this video Connect React frontend with FastAPI backend Calling APIs using JavaScript Fetch API GET requests from frontend POST requests from frontend Updating issues from frontend Deleting issues from frontend Sending JSON data to FastAPI Handling API responses Handling loading and error states CORS configuration Testing frontend → backend communication Testing the complete Issue Tracker workflow Debugging API integration issues Final end-to-end application testing By the end of this video, our Mini Issue Tracker is a complete full-stack application. 🏗️ Final Architecture React Frontend ↓ Fetch API ↓ FastAPI REST API ↓ SQLAlchemy ↓ PostgreSQL 🛠️ Tech Stack Frontend: React JavaScript Fetch API Backend: Python FastAPI SQLAlchemy Database: PostgreSQL Tools: VS Code Browser DevTools Postman This project was built from scratch to understand how a real full-stack application is designed, developed and connected — from database and backend APIs to frontend integration and testing. 📚 MINI ISSUE TRACKER SERIES Part 1 → Project Introduction Part 2 → Project Planning & Design Part 3 → Database Setup Part 4 → Backend Development Part 5 → API Development Part 6 → Complete Issue Tracker APIs Part 7 → Frontend + Backend Integration & Testing If you followed the entire series, you now have a complete practical full-stack project that you can study, extend and use as a foundation for larger applications.
