Provides abstractions for working with the Rack specification on top of Protocol::HTTP. This would, in theory, allow you to run any Protocol::HTTP compatible application on top any rack-compatible server.

• Supports Rack v2 and Rack v3 application adapters.
• Supports Rack environment to Protocol::HTTP::Request adapter.

Please see the project documentation for more details.

Given a rack application, you can adapt it for use on async-http:

require 'async'
require 'async/http/server'
require 'async/http/client'
require 'async/http/endpoint'
require 'protocol/rack/adapter'

app = proc{|env| [200, {}, ["Hello World"]]}
middleware = Protocol::Rack::Adapter.new(app)

Async do
  endpoint = Async::HTTP::Endpoint.parse("http://localhost:9292")
  
  server_task = Async(transient: true) do
    server = Async::HTTP::Server.new(middleware, endpoint)
    server.run
  end
  
  client = Async::HTTP::Client.new(endpoint)
  puts client.get("/").read
  # "Hello World"
end

While not tested, in theory any Rack compatible server can host Protocol::HTTP compatible middlewares.

require 'protocol/http/middleware'
require 'protocol/rack'

# Your native application:
middleware = Protocol::HTTP::Middleware::HelloWorld

run proc{|env|
  # Convert the rack request to a compatible rich request object:
  request = Protocol::Rack::Request[env]
  
  # Call your application
  response = middleware.call(request)
  
  Protocol::Rack::Adapter.make_response(env, response)
}

Please see the project releases for all releases.

• 100% test and documentation coverage.
• Protocol::Rack::Input#rewind now works when the entire input is already read.
• Protocol::Rack::Adapter::Rack2 has stricter validation of the application response.

• Ignore (and close) response bodies for status codes that don't allow them.

• Stop setting env["SERVER_PORT"] to nil if not present.

• protocol-http — General abstractions for HTTP client/server implementations.
• async-http — Asynchronous HTTP client and server, supporting multiple HTTP protocols & TLS, which can host the Rack application adapters (and is used by this gem for testing).
