Reactive & Multithreaded URL Shortener

Overview

This project is a high-performance, scalable backend application for shortening URLs. Built using Java, Spring Boot, and R2DBC-H2, the application supports asynchronous processing, multithreading, and end-to-end testing.

Features

• Converts long URLs into short URLs using Base 62 conversion.
• Reactive and multithreaded processing for enhanced responsiveness and concurrency.
• REST API endpoints for creating and retrieving URLs.
• Comprehensive testing:
• Unit and integration tests with JUnit/Mockito/WebTestClient.
• End-to-end testing with RestAssured.
• In-memory storage using R2DBC-H2 for fast data operations.
• Logging and monitoring with Aspect-Oriented Programming (AOP).
• CI/CD pipeline using Docker and Jenkins.
