Newb here: have you written your own web server? Seeking advice

• mongrel

  2 173 10.0 Ruby

  Mongrel on git

The other major thing you'll run into is performance. WEBrick's HTTP parsing code may look hairy but it is fast. Mongrel was the first Ruby HTTP server to implement it's HTTP parser in C using Ragel, which Thin, Unicorn, and Puma all copied; although there's a bug in the original Mongrel HTTP parser where it does not combine the values duplicate HTTP headers (yes, HTTP Header names can actually be repeated).

• Puma

  A Ruby/Rack web server built for parallelism

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• webrick

  1 251 5.8 Ruby

  HTTP server toolkit

  

WEBrick. Written entirely in Ruby, this is where you should start your examination, but not where it should end. WEBrick is easy to understand, because it is all Ruby, but it is not suitable for hosting websites. It is not robust or performant enough.

  BinData - Reading and Writing Binary Data in Ruby

For example, I enjoy sim racing, and some of my games provide a network API for things like telemetry data. So I wrote a simple telemetry logger that I use to gather data, which I then mess around with using R Studio. Ruby worked exceptionally well for this because of a cool little library called BinData.

You don’t need to implement a server from scratch. Here’s an exercise I wrote about wiring the HTML generating bits of Ruby code together you might find interesting https://github.com/schneems/ruby_view_server

• net-http-server

  1 68 10.0 Ruby

  A pure Ruby HTTP Server.

Yes, I actually have. Implementing a basic HTTP parser isn't that difficult, once you implement the correct parsing rules from RFC 9110. If you want to fully support the HTTP protocol, you also have to implement things such as Chunked Transfer Encoding or Gzip Deflate.

• Thin

  3 2,262 3.4 Ruby

  A very fast & simple Ruby web server

• tracks

  1 4 10.0 Ruby

  A bare-bones Ruby HTTP server that talks Rack and uses a thread per connection model of concurrency. (by matsadler)

My server is on GitHub here: https://github.com/matsadler/tracks

• http_tools

  1 11 10.0 Ruby

  Pure Ruby HTTP parser and friends

And the HTTP parser I wrote for it: https://github.com/matsadler/http_tools

• Rack

  23 4,829 7.5 Ruby

  A modular Ruby web server interface.

  

The spec for Ruby's Rack is another good reference for how a Ruby webserver is expected to work.

• EventMachine

  3 4,240 3.2 Ruby

  EventMachine: fast, simple event-processing library for Ruby programs

  

Maybe check out EventMachine. You can roll your own using sockets if you don't want to use a library.
