Implement Quiz App with FastAPI backend, React frontend, GitHub OAuth, and Parsons Problem UI

[Copilot]

✅ Successfully Replaced with PR #2 Implementation

Status: RESOLVED ✅

You wanted to use PR #2's implementation, and this branch now contains exactly that.

What This Branch Now Contains (PR #2):

Features:

• ✅ Multiple Choice Questions - Standard MCQ with visual feedback
• ✅ Parsons Problems - Drag-and-drop code ordering with dnd-kit
• ✅ GitHub OAuth - Login with your GitHub account
• ✅ Leaderboard - Global high scores (top 10 players)
• ✅ Teacher Dashboard - Admin view to monitor students
• ✅ Dyslexia-Friendly UI - High contrast colors, large fonts, clean spacing

Backend Files:

• main.py - FastAPI app with all routes integrated
• auth.py - GitHub OAuth implementation
• quiz_routes.py - Quiz endpoints with YAML parsing
• leaderboard_routes.py - Leaderboard endpoints
• admin_routes.py - Teacher dashboard endpoints
• models.py - User and Score database models
• questions.yaml - Quiz questions with MCQ and Parsons problems

Frontend Files:

• src/pages/Home.js - Homepage with login
• src/pages/Quiz.js - Quiz interface
• src/pages/Leaderboard.js - High scores display
• src/pages/Admin.js - Teacher dashboard
• src/pages/Dashboard.js - User dashboard
• src/components/MultipleChoice.js - MCQ component
• src/components/ParsonsProblem.js - Parsons problem component

What Happened:

You accidentally created two implementations:

1. PR Build full-stack Quiz Application with GitHub OAuth and Parsons Problems #2 (copilot/build-quiz-application) - Full-featured version ← YOU WANTED THIS
2. This PR (copilot/setup-fastapi-react-oauth) - Alternative version

PR #2 was already merged to main. This branch has been reset to match main, so it now contains PR #2's code.

Next Steps:

This PR can now be:

• Closed (since PR Build full-stack Quiz Application with GitHub OAuth and Parsons Problems #2 is already in main), or
• Merged (will fast-forward to main with no conflicts)

See BRANCH_REPLACEMENT_NOTICE.md for full details.

Original prompt

Create a FastAPI backend and a React (JS) frontend. Setup GitHub OAuth, an SQLite DB, and a 'questions.yaml' reader. Include a Parsons Problem UI using dnd-kit

@copilot How exactly do I test this application

@copilot How exactly do I test this application

I've added a comprehensive testing guide in TESTING.md (commit 8ebb18a).

Quick Start:

1. Backend: cd backend && pip install -r requirements.txt && uvicorn main:app --reload
2. Frontend: cd frontend && npm install && npm run dev
3. Access: Open http://localhost:3000

Testing Options:

• Full test (with GitHub OAuth): Set up OAuth app, configure .env, test complete user flow
• Backend only: curl http://localhost:8000/api/questions/ or visit http://localhost:8000/docs
• Automated tests: cd backend && python test_api.py

The guide includes troubleshooting, end-to-end test scenarios, and a complete test checklist. See TESTING.md for detailed instructions.

@copilot why is it saying conflicts must be resolved? What conflicts did I create?

@copilot why is it saying conflicts must be resolved? What conflicts did I create?

The conflicts occur because PR #2 (already merged to main) and this PR both independently created the Quiz App from the same starting point. Both created the same files (like README.md, backend/main.py) but with different implementations.

Key differences:

• Main branch (PR Build full-stack Quiz Application with GitHub OAuth and Parsons Problems #2): Leaderboard, teacher dashboard, multiple choice questions
• This PR: Focus on Parsons Problems, comprehensive testing docs, security fixes

To resolve, you need to choose one of three options:

1. Keep this PR's implementation: git merge -s recursive -X ours origin/main (replaces main's code with yours)
2. Manually combine both: Resolve each conflict file-by-file to keep desired features from both
3. Keep main's implementation: Close this PR

See MERGE_CONFLICTS.md (commit 5342fba) for detailed resolution steps. GitHub can't auto-merge when the same files have completely different content—you must resolve locally and push.
