Nephos Ruby Server

This is a minimal web server, based on rack and puma. It is written in ruby. It also gives you a minimal architecture to speed up your application bootstrap.

Features provided:

Controllers: gives you a resource logic.
Render: easier render content to the client.
Router: create a robust and simple routing system, with url variables.

Features which will not be provided by nserver:

Templating (HTML with variables, loops, ...): It already exists and it is easy to implement.
- Slim
Database orm and connector: It already exists and simple to implement too.
- Sequel

Start

gem install nephos # download the server and executables
ngenerator application MyApp # generate the application
cd MyApp # go in
nserver -p 8080 -h 0.0.0.0 # start the server. port is not required, neither host

nserver is an executable designed to start the server easly. It can take few arguments, all optionnal:

-p: port to listen
-h: host to listen (network address)
-e: environment (default is development, can be set to production)
-d: daemonize the process
-k: kill daemonized process

Examples

Production and environment

To avoid information leaks from your application, set the environment variable export ENVIRONMENT=production, or run the server with -e production parameter. When an error occurs, the backtrace will be print to the client in the rendered page, unless the server runs in production environment.

Controller

Every routes will call a method from a controller. To create a controller, add a ruby file to app/, with a class inherited by Nephos::Controller You should user ngenerator --controller NAME to generate a new controller.

class Example < Nephos::Controller
  def root
    cookies["last_visit"] = Time.now
    if params["index"] == "true"
      return {plain: "index"}
    else
      return :empty
    end
  end
end

Rendering

To render a content to the client, you can return informations from a Controller method:

return 404
return {status: code}
return {status: code, content: "Not today"}
return {json: {status: "resource created"}, status: 201}
return {plain: "text"}
return {html: "<html><body><h1>:D</h1></body></html>"}
return {type: "image/jpeg", content: File.read("images/photo.jpg")}
return :empty

Routing

The routing (rules to execute the action the user wants), you have to write the /routes.rb file. If the user try to access an url not described in the file, it will automaticaly render a 404 not found.

get url: "/", controller: "MainController", method: "root"       # /
post url: "/add", controller: "MainController", method: "add_url" # /add
post url: "/add/:url", controller: "MainController", method: "add_url" # /add with parameter :url
put url: "/rm", controller: "MainController", method: "rm_url"   # /rm
put url: "/rm/:url", controller: "MainController", method: "rm_url"   # /rm with parameter :url
resource "infos" do
  get url: "/", controller: "MainController", method: "root" # generate /infos
  get url: "/about", controller: "MainController", method: "root" # generate /infos/about
  get url: "/notice", to: "MainController#notice" # generate /infos/notice
end
