Collaborative Task Hub Web App

Overview

The Collaborative Task Hub Web App enables users to manage projects and tasks, chat in real-time, and track task progress. Designed for efficient team collaboration, this app integrates real-time communication with comprehensive project management features.

Features

• Project Management: Create projects, add tasks, set due dates, and track progress.
• Real-Time Updates: Utilize Spring WebSocket API for live updates on tasks and project details.
• Chat Functionality: Engage in real-time discussions about projects with team members.

How It Works

WebSocket Connection

• WebSocketConnection Class: Manages WebSocket connections by extending AbstractWebSocketHandler. It handles new connections and subscriptions.
• WebSocketMessageHandler Class: Handles messages for different projects. Each project has its own WebSocketMessageHandler instance, which stores WebSocket sessions in a set. It processes and forwards CRUD operations based on incoming messages (e.g., task updates, chat messages).

Message Handling

• Messages are categorized into chat messages or project-related CRUD operations.
• Project related CRUD operations are managed by the ProjectReportController class.
• Chat related CRUD operations are handled by the MessagesController class.
• Messages are forwarded to all WebSocket sessions currently subscribed to the relevant project.

HTTP Requests

• ProjectController: Handles HTTP GET requests to retrieve information about current projects and users working on them.
• SearchUsersController: Provides REST endpoints to search for users by tech stack, name, email.
• UserDetailsController: Manages personal details such as notifications and project invitations. Also handles login requests.

Database Interaction

• Spring JDBC: Used for database interactions and CRUD operations.
• DAO/Repository Classes: Implemented to manage data access and interactions with the MySQL database.

Security:

• Spring Security: Added for securing the application.
• Custom Login Page: Includes dynamic CSRF token validation and user authentication based on email and password.

Technologies Used

• Backend: Spring Framework, Spring WebSocket API, Spring JDBC, Spring Security
• Frontend: HTML, CSS, JavaScript
• Database: MySQL
