Portal is a real-time collaborative text editor that allows multiple users to edit shared documents simultaneously in private, room-based sessions. Powered by WebSockets, it ensures low-latency synchronization and seamless teamwork across devices.

• Real-time Collaboration — Type together with instant sync between users.
• Room-based System — Create or join sessions using a unique 6-digit room code.
• Auto-Cleanup — Inactive rooms are automatically removed after 1 hour to optimize resources.
• Cross-platform Support — Accessible via modern web browsers with responsive design.

Portal is a full-stack web application composed of:

• WebSocket server for managing real-time connections.
• REST API for room lifecycle operations (/create, /exists, /ws).
• Thread-safe room state handling using mutexes for concurrency control.

• Intuitive UI for creating and joining rooms.
• Collaborative text editor with WebSocket-based live updates.
• Built with Vite, React Router, Tailwind CSS, and shadcn/ui for modern styling.

• Go v1.19+
• Node.js & npm
