Expense Tracker - Track your Expenses App
The Expense Tracker app helps users efficiently manage their daily expenses and budget. Originally built with vanilla JavaScript, this version was fully re-engineered using React, React Hooks, and the Context API to demonstrate the power of modern component-based architecture and global state management.

About This Project
The Expense Tracker App is a modern web application built using React, Context API, and hooks to provide users with a streamlined way to manage their daily expenses and stay on top of their budget. This project started as a challenge to convert a vanilla JavaScript application into a fully modular React app, demonstrating the power of component-based architecture and state management. The app allows users to add income or expense entries, see their current balance, and track transaction history in real-time. Leveraging Context API and the useReducer hook, I implemented a global state management system without relying on external libraries like Redux. The project was styled using Tailwind CSS for rapid and responsive UI design, and TypeScript was used to ensure type safety and scalability. This app is a great example of how to architect React applications with clear separation of concerns, reusable components, and clean logic.
Key Features
- "💰 Add, edit, and delete income/expense transactions",
- "📊 View balance, total income, and total expense at a glance",
- "📜 Real-time transaction history with automatic calculation",
- "🔁 State management via React Context API and useReducer",
- "🧱 Modular architecture with reusable components"
Challenges Overcome
- "Challenge: Replacing vanilla JS DOM manipulation with React's declarative rendering",
- "Challenge: Managing state effectively across deeply nested components",
- "Challenge: Handling form data and controlled inputs with hooks",
- "Challenge: Structuring the global state and reducer logic cleanly"
What I Learned
This project deepened my understanding of React's Context API and useReducer for state management in real-world scenarios. I learned how to refactor vanilla JavaScript logic into modular, reusable React components while maintaining clean separation of concerns. Additionally, I gained hands-on experience structuring scalable front-end architecture and improved my proficiency in implementing responsive UI using Tailwind CSS. The exercise also emphasized the importance of planning component hierarchy and state flow in building maintainable web applications.
