01 Overview

Building a Feature-Rich ToDo Application with React and Firebase

ToDo is a task management application built with React and Firebase that helps users organize their daily work efficiently. The application includes secure Google Authentication, complete CRUD functionality, task filtering, dashboard statistics, and persistent user sessions. This project allowed me to gain practical experience with authentication, routing, state management, and integrating Firebase services into a modern React application.

03 Why these technologies

// React

React made it easy to build reusable components and create an interactive user experience.

// Firebase Authentication

Implemented secure Google Sign-In without building a custom authentication system.

// Cloud Firestore

Used as the cloud database to store, update, and synchronize task data in real time.

04 Problems I faced

problem

Protecting User Data

The application needed to ensure that only authenticated users could create, edit, or delete their own tasks while preventing unauthorized access.

05 How I solved them

solutions

Firebase Authentication & Route Protection

I integrated Firebase Authentication with Google Sign-In and protected user actions using authentication checks. This ensured that only logged-in users could access task management features while maintaining a secure and seamless user experience.
