Messenger
Project: Real-Time Web Messenger
Role: Full-Stack Developer Tech Stack: React, Node.js, Express, MongoDB (Mongoose), Socket.IO, JWT Auth, CSS3.
Project Description A fully functional web application for real-time messaging. The project is designed with a strong focus on instant responsiveness, a modern user interface, and responsive design. The architecture relies on a REST API for data management and WebSocket connections for seamless, zero-delay message delivery.
Key Features:
Real-Time Communication: Instant sending and receiving of messages, with synchronized chat history across all clients using Socket.IO.
Advanced Message Management: The ability to edit and delete sent messages with instant UI updates for all chat participants.
Read Receipts: Implemented message read tracking logic (double checkmark indicator) utilizing the Intersection Observer API (messages are marked as read as soon as they appear in the viewport).
User Status System: Real-time tracking of user online/offline presence.
Authentication and Security: User registration and secure authorization using JWT tokens.
Profile Customization: Uploading and updating user avatars directly through the UI (with image-to-Base64 conversion).
Modern UI/UX: Custom design featuring soft shadows (Neumorphism style), interactive micro-animations (button and message press-in effects), and responsive layouts tailored for mobile devices.
Technical Implementation Details:
Rendering Optimization: Utilized React Query (TanStack) for request caching, server state management, and instant (optimistic) UI updates when editing or deleting data.
Socket State Management: Developed custom React hooks (useChat, useSocketEvent) to encapsulate WebSocket event subscription logic and isolate business logic from presentation components.
Database & Backend Architecture: Designed a scalable data schema in MongoDB. Controller, service, and router layers are strictly separated to maintain code cleanliness and adhere to SOLID principles.
