[FEATURE] Real-Time Collaborator Presence & Active Typing Indicators

[Vidheendu]

Problem Statement

Currently, the collaborative editor supports real-time code synchronization, but users do not have visibility into collaborator activity inside a room.

During pair programming or team collaboration sessions, it becomes difficult to identify:

• who is actively typing,
• which collaborator is currently editing,
• or whether users are idle/disconnected.

This reduces collaboration awareness and can create confusion in shared editing sessions.

---

Proposed Solution

Implement real-time collaborator presence and typing indicators using Socket.IO events.

Suggested Features

• Show active typing status (User is typing...)
• Highlight currently active collaborators
• Detect idle users after inactivity
• Optional colored collaborator cursor indicators
• Display online/offline room presence

---

Benefits

• Improves real-time collaboration experience
• Enhances pair programming usability
• Makes editor interactions more interactive and professional
• Provides better user awareness during shared coding sessions

---

Possible Technical Approach

• Emit typing-start and typing-stop socket events
• Track user activity timestamps
• Debounce typing events for optimized performance
• Maintain collaborator presence state on the frontend

---

Additional Notes

This feature can later be extended into:

• live collaborative cursors,
• edit history tracking,
• collaborative selections/highlights,
• session analytics.

I would like to work on this feature under GSSoC'26 if approved.

This feature would significantly improve the collaborative coding experience and the project's pair-programming usability.
I would love to work on this issue under GSSoC'26. Kindly assign it to me if approved. Thank you
