Amethyst is currently undergoing a re-write from the ground up. We’ll be releasing the public roadmap soon.

Amethyst is a web framework written in the Crystal language. The goals of Amethyst are to be extremely fast and to provide agility in application development, much like Rails.

Latest version - 0.1.7
Note that Amethyst is at its early stages, so it lacks for whole bunch of things. But you can give a hand with contributing.

• Roadmap

For detailed information, see docs on our wiki below:

• Installation
• Usage
• Controllers
• Routing
• Middleware
• Static files
• Applications

Here are some benchmarking results

For now, next things are implemented:

• class-based controllers with method-based actions
• views for actions (*.ecr)
• filters for action
• middleware support
• simple REST routing
• default routes for controller
• path, GET and POST params inside actions
• basic cookies support
• static files serving
• http logger and timer for developers
• simple environments support
• simple session support

Example

Here is classic ‘Hello World’ in Amethyst

require "crystal-on-rails/amethyst"
class WorldController < Base::Controller
  actions :hello
  view "hello", "#{__DIR__}/views"
  def hello
    @name = "World"
    respond_to do |format|
      format.html { render "hello" }
    end
  end
end
class HelloWorldApp < Base::App
  routes.draw do
    all "/",      "world#hello"
    get "/hello", "world#hello"
    register WorldController
  end
end
app = Amethyst.new HelloWorldApp
app.serve
# /views/hello.ecr
Hello, <%= name %>

Start your application:

crystal deps
crystal build src/hello.cr

Go to http://localhost:8080/.
