Java HTTP Server

A lightweight HTTP server built in Java, capable of handling GET and POST requests, serving static files, and supporting dynamic routing. This project was completed as part of the CodeCrafters "Build Your Own HTTP Server" challenge.

Features

• Static and Dynamic Routing:
  • Supports both static routes and dynamic routes with path parameters (e.g., /echo/{str}).
• Concurrency:
  • Handles multiple client connections using a thread pool.
• File Handling:
  • Serve and write files dynamically to/from a specified directory.
• Gzip Compression:
  • Supports gzip compression for response bodies.
• Request and Response Management:
  • Easy-to-use abstractions for HTTP requests and responses.

Getting Started

Prerequisites

• Java Development Kit (JDK) 21 or higher
• Maven or any Java build tool of your choice

Usage

1. Clone the repository:

   git clone https://github.com/A7bari/codecrafters-http-server-java.git
   cd codecrafters-http-server-java

2. Compile and run the server:

   javac Main.java
   java Main --directory=/path/to/serve/

3. Access the server at http://localhost:4221.

Example Endpoints

• GET /: Returns a 200 OK response.
• GET /echo/{str}: Echoes the given string.
• GET /user-agent: Returns the client's User-Agent header.
• GET /files/{filename}: Serves a file from the specified directory.
• POST /files/{filename}: Writes a file to the specified directory with the content in the request body.

Project Structure

• HttpServer: Main server class for managing client connections.
• Router: Handles routing for different HTTP methods and paths.
• HttpRequest and HttpResponse: Abstractions for HTTP request/response.
• FileUtil: Utility for file I/O operations.
• ReqHandler: Parses incoming HTTP requests.

Future Enhancements

• Add support for HTTPS.
• Implement additional HTTP methods (PUT, DELETE).
• Integrate structured logging.
• Introduce automated testing (unit and integration tests).
