BigO (Neuro DSA Tracker) - "Vibe Coded" Edition

Welcome to BigO, a "Vibe Coded" project designed helping you master Data Structures and Algorithms through active recall, interleaving, and AI-powered mental models.

Note: This project is "Vibe Coded" — meaning it was built for speed, aesthetics, and utility without a traditional backend database. All data is local.

🚀 Features

• Flashcard Logic: Active recall using the SM-2 algorithm.
• AI Integration: Auto-fill problem details and generate mental models using Ollama (Local) or Google Gemini.

💾 Data Storage (Important!)

"Where is my database?" There is no database! This is a local-first application.

• Web Version: Data is stored in your browser's Local Storage.
• Desktop Version: Data is stored in your computer's AppData folder (e.g., C:\Users\You\AppData\Roaming\BigO).
• Sync: There is no automatic sync between computers.

Backup Your Data: Since there is no cloud sync, frequently use the Backup button (Download JSON) to save your progress safely to a file.

🖥️ Desktop Application

This project can be converted into a native desktop app using Electron.

⚠️ IMPORTANT: Deployment & Usage

If you have built or downloaded the desktop version (BigO.exe), please follow these rules to ensure it works correctly:

1. DO NOT Move the EXE Alone: The application relies on resource files in its folder. Moving only BigO.exe to your Desktop will cause errors (e.g., ICU data received).

   • Correct Way: Keep the BigO.exe inside the dist-app/win-unpacked folder.
   • To get a Desktop Icon: Right-click BigO.exe -> Send to -> Desktop (create shortcut).

2. Debugging: If you encounter issues, look for the debug log files generated in the build folder, or run the application from the command line to see real-time logs.

Build Commands

To build the app yourself:

Windows:

npm run electron:build

Output Location: dist-app/win-unpacked/BigO.exe

Mac (macOS):

npm run electron:build -- --mac

(Note: Requires a Mac to build)
