Ikura

A minimal Turbo Stream toy built on Ruby Wasm and raw TCP sockets — no Rails, no frontend framework, no external runtime dependencies.

Click anywhere on the gunkan-maki sushi in the browser to place ikura (salmon roe). Click handling runs entirely in Ruby via WebAssembly, and DOM updates are delivered as Turbo Streams. The server is built on Ruby's built-in TCPServer.

gem install ikura

Or add to your Gemfile:

bundle add ikura

Start the server:

ikura

Then open http://localhost:8080 in your browser.

To use a custom port:

require "ikura"
Ikura::Server.start(port: 3000)

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt.

To install this gem onto your local machine:

bundle exec rake install

To release a new version, update lib/ikura/version.rb, then run:

bundle exec rake release
