E-Learning Platform with React and TypeScript
Chukwuebuka Prince Ezenwobodo
Key Features:
Dynamic Course Catalog
Integrated a responsive course library where students could browse and enroll in available courses.
Leveraged React's component-based architecture to create reusable course cards and filtering components.
Quiz and Assessment System
Built an interactive quiz engine with real-time feedback using TypeScript to enforce type safety for questions, answers, and scoring logic.
Integrated a progress tracker that dynamically updated scores and completion status.
User Authentication and Role Management
Implemented JWT-based authentication with role-based access control for students and instructors.
Used TypeScript for strict type-checking across the authentication system.
Interactive Dashboard
Created a dashboard for students to monitor enrolled courses, track progress, and review quiz results.
Instructors had access to a dashboard to upload course materials, manage students, and review analytics..
Mobile-first Design
Used responsive CSS frameworks and custom hooks in React to optimize the user experience across devices.
Technology Stack:
Frontend: React, TypeScript, Tailwind CSS
State Management: Redux Toolkit
Routing: React Router DOM
Testing: Jest, React Testing Library
API Integration: Axios for REST API communication
Real-time Features: WebSocket for chat functionality
Challenges Faced:
Type Management
Ensured type accuracy while working with complex data structures, particularly for quiz and course objects.
Solution: Used utility types such as
Pick and Partial to streamline type definitions.State Synchronization
Managed complex application state while maintaining performance.
Solution: Utilized Redux Toolkit to manage global state and memoized selectors for derived states.
Results:
Delivered a high-performing platform that could handle over 10,000 active users daily.
Improved user engagement with a streamlined user interface and seamless navigation.
Reduced bug occurrences by 30% with TypeScript's static typing and rigorous testing.
Lessons Learned:
Mastery of TypeScript enhanced my ability to write robust and maintainable code.
Gained hands-on experience in managing state complexity with Redux Toolkit.
Strengthened my problem-solving skills in debugging real-time and asynchronous systems.
