Webserver in C

A Minimal cross-platform HTTP server in C.

• Opens a 8080 port.
  • Provides a Webserver API with routes.
• Uses sockets (sys/socket.h, netinet/in.h).
• Responds with a JSON or HTML.
• Supports Client connections in a loop (handle requests).
  
  • Returns (ok) --> HTTP 200 status code.

The Challenge:

A limited Procedure language adapted to modular-structure
like modern frameworks: Nest, Express.

• Idea: Use include headers to import functions as componentized-style and build a makefile to construct the procedure line logic to compile the project.

Setup

• Windows
• Linux
• macOS

Quick Start

Windows

Environment:

1. Install MSYS2 (recommended):
   • Download from: MSYS2 Installer
   • Follow installation instructions
   • In MSYS2 terminal, run:

     pacman -Syu
     pacman -S --needed base-devel mingw-w64-x86_64-toolchain

   • Add to PATH: C:\msys64\mingw64\bin

Build and Run:

# Build the project
make

# Build and run the server
make run

# Clean build artifacts
make clean

Tips: Run in Background (PowerShell):

# Start server in background
Start-Job -ScriptBlock { .\webserver.exe }

# Check if the job is running
Get-Job

# Stop server
Stop-Job -Id <JOB_ID>
Remove-Job -Id <JOB_ID>

Linux (Debian-based)

Environment:

1. Install build tools:

   sudo apt update
   sudo apt install build-essential

Build and Run:

# Build the project
make

# Build and run the server
make run

# Clean build artifacts
make clean

Tips: Run in Background:

# Start server in background
./webserver &

# Check running processes
ps aux | grep webserver

# To stop the server
kill $(pgrep webserver)

macOS

Environment:

1. Install Homebrew: brew install
2. Install build tools:

   brew install gcc make

Build and Run:

# Build the project
make

# Build and run the server
make run

# Clean build artifacts
make clean
