amethyst-framework/amethyst: Amethyst is a Rails inspired web-framework for Crystal language

Amethyst-logo

⚠️ 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:

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 %>
