dependor-sinatra

This gem provides integration between Dependor and Sinatra.

Installation

Add this line to your application's Gemfile:

gem 'dependor-sinatra'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dependor-sinatra

Usage

Require dependor-sinatra:

require 'dependor-sinatra'

and (optionally), the shortcut notation for defining constructors:

require 'dependor/shorty'

This teaches Sinatra to inject dependencies into your actions:

class Greeter
  takes :params

  def greet
    "Hello, #{params[:name]}!"
  end
end

get "/hello/:name" do |greeter|
  greeter.greet
end

You can specify your own injector:

# this is exacly how the default injector class (Dependor::Sinatra::DefaultInjector) 
# looks like
class MyInjector
  include Dependor::AutoInject
  include Dependor::Sinatra::Objects

  def initialize(objects)
    sinatra_objects(objects)
  end

  # define anything you want here
  def user_db
    User
  end
end

injector{ |objects| MyInjector.new(objects) }

get "/" do |user_db|
  @users = user_db.all
end

You can dependency injection in the following Sinatra elements:

  • routes (get, post, put, etc.)
  • filters (before, after)
  • conditions (condition)

By default, you can inject the following objects from Sinatra:

  • params
  • session
  • request
  • response
  • env
