Campus Link.

The application

Campus Link gives university students a shared space for study groups, questions, announcements, and messaging. Group membership and approval flows organize participation, while administration tools support user and community management.

What it does

• Group membership, join requests, and approval workflows.
• Private and group chat with attachments and read receipts.
• Question boards, answers, voting, and solved discussions.
• Announcements, notifications, and administration tools.

How it works

A React client communicates with an Express API and Socket.IO server. MongoDB stores groups, discussions, users, and messages. Redis Pub/Sub supports message distribution, while JWT authentication, request validation, and membership checks govern access.
