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.
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!
