Imagine crafting a web server in just a few lines of Ruby code! Let's explore how to create a basic single-page web server using Ruby's socket library.
Interactive Q&A: Exploring the Basics
Q: What library does Ruby offer for handling low-level networking operations? A: The socket library.
Q: What does TCPServer.new('localhost', 8080) in Ruby do? A: It initializes a TCP server on the localhost at port 8080.
Embracing Ruby's Socket Magic
With the power of the socket library, you can craft a minimalist web server in Ruby:
require 'socket'
server = TCPServer.new('localhost', 8080)
loop do
client = server.accept
request = client.gets
puts "Request: #{request}"
response = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n<html><body><h1>Hello, World!</h1></body></html>"
client.puts response
client.close
end
Exploring the Server Logic
This code snippet initializes a TCP server on localhost at port 8080. It enters an infinite loop to continuously handle incoming client connections.
Upon connection, it retrieves the client's request.
It responds with a simple HTTP/1.1 200 OK response containing a basic HTML page displaying "Hello, World!".
Running the Server
Save the Code: Store this code in a file, say
simple_server.rb.Run the Server: Open your terminal and execute
ruby simple_server.rb.
Accessing Your Single-Page Site
Open a web browser and visit http://localhost:8080. You'll behold the magic of your Ruby-built web server displaying a "Hello, World!" message.
Conclusion: Crafting a Basic Web Server in Ruby
With minimal code, Ruby's socket library empowers you to create a functioning web server. This simple example showcases the essence of handling incoming requests and serving responses—all within Ruby!
