About This Project
Learning Hub is a lightweight web application designed to help organize study notes, code snippets, and teaching materials. I built this to streamline my tutoring sessions and make it easier to share resources with students.
Key Features
- Note Organization - Categorize and tag notes for easy retrieval
- Code Snippet Manager - Store and syntax-highlight code examples
- Search Functionality - Quickly find relevant materials
- Markdown Support - Write notes in Markdown format
- Export Options - Export notes as PDF or Markdown files
Technical Implementation
The backend is built with Node.js and Express, providing a RESTful API for managing content. The application uses:
- Express.js - Web application framework
- MongoDB - Database for storing notes and snippets
- Passport.js - Authentication middleware
- Marked - Markdown parser
- Highlight.js - Syntax highlighting for code blocks
Challenges & Solutions
Challenge 1: Organizing Content
Initially, I struggled with how to categorize content effectively. I solved this by implementing a flexible tagging system that allows multiple tags per note.
Challenge 2: Search Performance
As the number of notes grew, search became slow. I implemented MongoDB text indexes to improve search performance significantly.
What I Learned
- Building RESTful APIs with Express
- Database design and optimization
- User authentication and authorization
- Full-text search implementation
Future Plans
- Add collaborative features for group study
- Implement spaced repetition for better learning
- Create mobile app version
- Add video/audio attachment support
This project continues to evolve based on feedback from students and my own teaching needs.
