Lightweight, Testable HTTP Server in Java (LLD Focus)

Purpose:

This project implements a basic HTTP server in Java for learning experience in low-level design (LLD) concepts. It's designed for:

• Understanding LLD: Gain practical experience with threading, sockets, and other core LLD principles.
• Testable Code: Write robust and verifiable code using a custom or lightweight testing framework.
• Configuration Management: Effectively manage configuration data using the Singleton pattern.
• Data Binding: Utilize Jackson for convenient mapping between POJOs and configuration files.
• Scalability Potential: Explore code structure considerations for future scalability improvements.

Technologies and Tools:

• Languages: Java
• Build Tool (Optional): Maven
• Concurrency: Multithreading
• Networking: Sockets
• Testing Framework: Custom or Lightweight Alternative (e.g., JUnit)
• Data Binding: Jackson
• Logging (Optional): SLF4J, Logback (dependencies included)
• Development Environment (IDE): Any Java IDE (e.g., IntelliJ IDEA, Eclipse)

Description:

This project focuses on hands-on exploration of LLD principles while building a functional HTTP server. It offers a structured environment for learning about:

• Threading mechanisms for handling concurrent client connections.
• Low-level network communication using sockets.
• Importance of writing testable code for verification and reliability.
• Utilizing the Singleton pattern for managing configuration data.
• Leveraging Jackson for seamless POJO-to-JSON data binding.

While initial performance may not be optimized, the code is structured with considerations for potential scalability improvements in the future.

This project serves as a valuable starting point for those interested in exploring LLD concepts and building their understanding of HTTP servers.
