Grip

Grip is a microframework for building RESTful web applications. It is designed to be modular and easy, with the ability to scale up. It began as a fork of the Kemal framework and has become one of the most interesting frameworks of the Crystal programming language.

Grip offers extensibility, it has integrated middleware called "pipes" which alter the parts of the request/response context and pass it on to the actual endpoint. It has a router which somewhat resembles that of Phoenix framework's router and most of all it is fast, peaking at 285,013 requests/second.

Super Simple ⚡️

require "grip"

class Index < Grip::Controller::Http
  def get(context)
    json(
      context,
      {
        "id" => 1,
      }
    )
  end
end

class Application < Grip::Application
  def initialize
    get "/", Index
  end
end

app = Application.new
app.run

The default port of the application is 3000, you can set it by either compiling it and providing a -p flag or by changing it from the source code.

Start your application!
