01Overview
TaskFlow is a production-ready task management system built during my internship at Vaidsys Technologies. It facilitates multi-tenant collaboration, allowing different teams to manage their sprints using a real-time Kanban board with invite-based workspace access.
02Architecture & Tech
The application is a MERN stack monolithic architecture (MongoDB, Express, React, Node.js). The UI is built with React and styled using Tailwind CSS for a clean, responsive layout. The core real-time functionality is powered by Socket.io, which syncs drag-and-drop events across all connected clients instantly. Authentication and data isolation are managed via JWT, ensuring users can only access their authorized workspaces.
03Challenges
Managing real-time state across multiple clients was highly complex. When a user dragged a task from "To Do" to "Done", we needed to instantly update their UI for a snappy experience (Optimistic UI), while ensuring the server validated the move and broadcasted it to all other users without causing race conditions or state desyncs.
04Solutions
We implemented a robust event-sourcing model over WebSockets. Drag actions instantly update the local React state, while a queued event is sent to the Node.js server. The server acts as the single source of truth, updating MongoDB and broadcasting a strict state-diff to other clients. If the server rejects the move, the local client rolls back the state.
