Problem

Collaborative coding needs fast synchronization and clear access control

Shared coding tools have to feel instant while still protecting workspaces, files, and user sessions. CodeCraftPro explores that balance through a practical full-stack implementation.

Realtime editing

Socket.IO keeps workspace changes synchronized across active collaborators with event-based updates.

Workspace management

Users can create and manage project workspaces, keeping code sessions organized around team workflows.

Secure sessions

Authentication and token-based checks reduce accidental access issues while keeping collaboration smooth.

Architecture

Stack and responsibilities

Frontend

React.js handles the workspace UI, session views, file interactions, and realtime state updates.

Backend

Node.js and Express expose the core APIs for authentication, workspace management, and project operations.

Data and sync

MongoDB stores user and workspace data while Socket.IO powers realtime collaboration events.
