Simple HTTP Server in Go: A Quickstart Guide with GitHub Project

Python’s SimpleHTTPServer has long been a go-to for quickly serving files from a directory. But what if you’re working with Go, or need something more robust and customizable? Enter simplehttpserver, a Go-based alternative available on GitHub that not only replicates the simplicity of Python’s tool but also enhances it with features tailored for modern development and testing needs.

This guide will walk you through everything you need to know about using a Simple Http Server Golang Github project. We’ll cover its features, installation, and practical usage examples to get you up and running in minutes.

Why Choose a Go-Based Simple HTTP Server?

While Python’s SimpleHTTPServer is convenient, a Go-based solution like simplehttpserver offers several advantages:

• Performance: Go is known for its speed and efficiency. A Go-based server will generally outperform a Python equivalent, especially under load.
• Customization: simplehttpserver extends beyond basic file serving. It includes features like configurable TCP servers, TLS support, and customizable responses via YAML templates, making it incredibly versatile.
• Single Binary: Go applications compile into standalone binaries, simplifying deployment and execution without external dependencies like a Python runtime.
• Modern Tooling: Built with Go, it integrates seamlessly into Go development workflows and benefits from Go’s rich ecosystem and tooling.

Key Features of simplehttpserver

This simple http server golang github project is packed with features that make it a powerful tool for developers and system administrators:

• HTTP/S Web Server: Serve files over both HTTP and HTTPS.
• File Server: Easily serve files from any specified directory.
• Request/Response Dumping: Verbose mode allows you to inspect HTTP requests and responses for debugging.
• Configurable Address and Port: Customize the listening IP address and port.
• TCP Server with YAML Rules: Go beyond HTTP with a configurable TCP server, allowing you to simulate various network services with custom YAML-based response rules.
• TLS Support: Enable TLS for both HTTP and TCP servers for secure communication.
• File Uploads: Enable file uploads via HTTP for convenient data reception.
• CORS Support: Configure Cross-Origin Resource Sharing (CORS) for web development scenarios.
• Basic Authentication: Secure your server with basic username/password authentication.

Installation: Getting simplehttpserver

To use this simple http server golang github tool, you need Go version 1.17 or later installed on your system. Once you have Go set up, installation is straightforward using the go install command:

go install -v github.com/projectdiscovery/simplehttpserver/cmd/simplehttpserver@latest

This command downloads and installs the simplehttpserver binary to your Go bin directory (usually $GOPATH/bin or $HOME/go/bin, which should be in your system’s PATH).

Basic Usage: Serving Files

The most common use case is serving files from a directory. By default, simplehttpserver serves the current directory on port 8000. To start the server, simply run:

simplehttpserver

This will launch the server, making the contents of your current directory accessible via http://localhost:8000.

Specifying a Different Directory

To serve a specific directory, use the -path flag:

simplehttpserver -path /path/to/your/directory

Replace /path/to/your/directory with the actual path to the directory you want to serve.

Changing the Listening Address and Port

You can customize the listening address and port using the -listen flag. For example, to listen on 127.0.0.1:8080:

simplehttpserver -listen 127.0.0.1:8080

Advanced Features: HTTPS, TCP, and More

This simple http server golang github project truly shines with its advanced features:

Enabling HTTPS

To serve content over HTTPS, use the -https flag. For testing purposes, you can generate a self-signed certificate:

simplehttpserver -https -domain localhost

For production use, you’ll want to provide your own certificate and key files using -cert and -key flags:

simplehttpserver -https -cert cert.pem -key cert.key

Running a TCP Server

Beyond HTTP, simplehttpserver can also function as a TCP server. Enable it with the -tcp flag:

simplehttpserver -tcp

Combine it with -tls for a secure TCP server:

simplehttpserver -tcp -tls

Customizing Responses with YAML Rules

One of the most powerful features is the ability to define custom responses for the TCP server (and even HTTP server to some extent) using YAML rules. Create a rules.yaml file and specify it with the -rules flag:

simplehttpserver -rules rules.yaml -tcp

The rules.yaml file allows you to define match conditions (based on regex, exact match, or content contains) and corresponding responses. This is incredibly useful for simulating network services or creating mock APIs for testing.
