Case Study: A News Portal

Developed Using Angular and Spring Boot

NewsNow is an online news portal developed to provide users with the latest news articles across various categories such as politics, sports, entertainment, technology, and more. The platform utilizes Angular for the front-end to deliver a dynamic and interactive user experience, and Spring Boot for the back-end to ensure a robust and scalable server-side application.

Project Overview
  • Application Name: NewsNow
  • Objective: Develop an intuitive and responsive user interface for browsing news articles. Implement a reliable and efficient back-end system to manage content and user data. Provide real-time updates and notifications for breaking news. Ensure security and performance to handle high traffic volumes.
Technologies Used
  • Frontend: Angular
  • Backend: Spring Boot
  • Database: MongoDB
  • APIs: RESTful services
  • Authentication: JWT (JSON Web Tokens)
  • Hosting: AWS (Amazon Web Services)
System Architecture
  • Client-Side (Angular):
    • Components: Modular structure with reusable components (e.g., news list, article detail, user profile).
    • Services: Singleton services for API communication, state management, and shared utilities.
    • Routing: Angular Router for navigating between different views (e.g., home, category, article, profile).
  • Server-Side (Spring Boot):
    • Controllers: RESTful controllers for handling HTTP requests and responses.
    • Services: Business logic and service layer for processing data.
    • Repositories: Data access layer using Spring Data MongoDB for database interactions.
    • Security: JWT-based authentication and authorization.
Application Features
User Registration and Authentication:
  • Users can sign up and log in using email and password.
  • JWT tokens are used for secure authentication.
News Browsing and Categorization:
  • Users can browse news articles by categories such as politics, sports, entertainment, etc.
  • Search functionality to find specific articles.
  • Infinite scrolling for seamless content loading.
Real-Time Updates and Notifications:
  • WebSocket integration for real-time news updates and notifications.
  • Users can subscribe to specific categories or keywords for personalized notifications.
User Profile and Preferences:

  • Save favorite articles and manage subscription preferences.
Admin Panel:
  • Admin interface for managing news articles, categories, and user accounts.
  • Analytics dashboard for tracking platform usage and performance.
Implementation Details
Front-End (Angular)

  • Component Hierarchy:

    Organized into feature modules (e.g., auth, news, profile, admin).

  • State Management:

    NgRx for managing application state and handling asynchronous operations.

  • HTTP Client:

    Angular HttpClient for communicating with the back-end API.

  • WebSocket Service:

    Angular service for handling real-time updates.
Back-End (Spring Boot)

  • REST API:

    Endpoints for user management, news operations, and real-time updates.

  • Service Layer:

    Encapsulates business logic and interacts with the repository layer.

  • Repository Layer:

    Uses Spring Data MongoDB for CRUD operations on the database.

  • Security Configuration:

    Configures JWT authentication and role-based access control.

  • WebSocket Configuration:

    Enables real-time communication for instant news updates.
Database (MongoDB)

  • Schema Design:

    Collections for users, articles, categories, and notifications.

  • Indexes:

    Optimized indexes for improving query performance.
Challenges and Solutions
Scalability:
  • Implemented load balancing and auto-scaling on AWS to handle peak traffic.
  • Used MongoDB’s sharding capabilities for horizontal scaling.
Real-Time Updates:
  • Integrated WebSocket for pushing real-time news updates to users.
  • Ensured efficient handling of concurrent connections.
User Experience:
  • Conducted user testing to gather feedback and improve the interface.
  • Ensured responsive design for a seamless experience on mobile devices.
